SQL Server provides a platform to construct and pull off informations applications. In add-on, it combines informations analysis, coverage, integrating, and presentment services that enable organisations to construct and deploy efficient Business Intelligence ( BI ) solutions.
This chapter discusses the importance of a database waiter. In add-on, it provides an overview of SQL Server, its constituents, and characteristics. Further, this chapter introduces the Structured Query Language ( SQL ) that is used to pull strings the informations in a database waiter. Last, it discusses the tools provided by SQL Server to better the productiveness of the database developer and pull off the waiter.
In this chapter, you will larn to:
Appreciate SQL Server as a database waiter
Identify the SQL Server tools
Introduction to SQL Server
Every organisation needs to keep information related to employees, clients, concern spouses, or concern minutess. Organizations build concern applications with a user-friendly interface to hive away and pull strings this information and to bring forth studies. For this, they need a platform to hive away and keep this information in an efficient manner. Assorted Database Management Systems ( DBMS ) and Relational Database Management Systems ( RDBMS ) , such as SQL Server, Oracle, and Sybase, provide the platforms for hive awaying and keeping this information.
SQL Server is a information engine introduced by Microsoft. It provides an environment used to make and pull off databases. It allows secure and efficient storage and direction of informations. In add-on, it provides other constituents and services that support the concern intelligence platform to bring forth studies and aid in analysing historical informations and foretelling future tendencies.
As a database developer, it is of import for you to place the function of a database waiter in an organisation. You can plan a database efficaciously if you know all the constituents and services of SQL Server. In add-on, you need to understand the rudimentss of SQL, a linguistic communication that is used to question and pull off informations.
Role of a Database Server
Organizations have ever been hive awaying and pull offing concern informations. Earlier, organisations used to hive away informations on paper. With an addition in the use of computing machines, organisations started keeping the same information in computing machines. Data was stored in an organized manner, and it was besides easy to recover informations faster than earlier. As informations retrieval became easy and fast, organisations startedA utilizing concern applications to back up the concern operations.
Business applications accept informations as input, procedure the informations based on concern demands, and supply informations or information as end product. For illustration, an application maintains the inside informations of the figure of autos sold for a peculiar trade name, such as Ferrari. Each auto has a alone designation figure that is already stored in an application. Whenever a sale happens, the application checks whether the alone designation figure provided for the auto is right or non. If the alone designation figure is right so the sale inside informations for the same is updated in the application. The information is saved and an end product message corroborating that the information has been saved is displayed to the user. This procedure of look intoing whether the alone designation figure exists in the system or non is called a concern regulation.
See another scenario. The Human Resource section of an organisation uses an application to pull off the employee informations. The users need to add the inside informations of new employees. For this, the application provides an interface to come in the employee inside informations. These inside informations are validated for truth based on concern regulations. For illustration, a concern regulation is defined to look into that the day of the month of connection of the new employee is less than or equal to the current day of the month. If the information meets the demands, it is saved in the information shop.
Based on the predating scenario, a concern application can hold the undermentioned elements:
The User Interface ( UI ) or the presentation component through which information is entered.
The application logic or the concern regulation component, which helps in formalizing the entered informations.
The information storage or the informations direction component, which manages the storage and retrieval of informations.
These elements form the base of the theoretical accounts or architectures used in application development. All these elements can be on the same computing machine as a individual procedure or on different computing machines as different procedures. Depending on the arrangement of these elements, the application architecture can be categorized as:
In a single-tier architecture, all elements of a concern application are combined as a individual procedure. If multiple users need to work on this application so it needs to be installed on the computing machine of every user. This type of architecture has one disadvantage. In instance some mistakes are identified in the application so after rectifying the same, the application has to be installed once more on the system of every user. This is a time-consuming procedure.
To work out the jobs of single-tier application, two-tier architecture was introduced. In two-tier architecture, the application is divided into two parts. One portion handles the informations, while the other provides the user interface. Therefore, this architecture is called two-tier architecture. These two parts can be located on a individual computing machine or on separate computing machines over a web.
The portion that handles the UI is called the client grade. The portion that implements the application logic and validates the input informations based on the concern regulations is called the waiter grade, as shown in the undermentioned figure.
A Two-Tier Architecture
In this architecture, the care, ascent, and general disposal of informations is easier, as it exists merely on the waiter and non on all the clients.
A two-tier architecture is besides called the client-server architecture. A client sends the petition for a service and a waiter provides that service. Most RDBMSs, such as Microsoft Access, SQL Server, and Oracle, support client-server architecture. RDBMS provides centralised functionality while back uping many users.
When implementing complex concern solutions in a two-tier architecture, the grade on which the concern logic is implemented becomes over laden. As a consequence, it takes more clip to put to death. Therefore, to supply farther flexibleness, the two-tier architecture can be split into three grades. In three-tier architecture, the first grade is the client grade. The 2nd or the in-between grade is called the concern grade. The 3rd grade is called the waiter grade. The waiter grade contains a database waiter that manages the information.
In this architecture, an extra grade called a concern grade has been added between the client grade and the waiter grade, as shown in the undermentioned figure.
A Three-Tier Client/Server Architecture
The concern grade consists of all the concern regulations. It consists of the application logic that implements concern regulations and validates the information. The advantage of a three-tier application is that it allows you to alter the concern regulations without impacting the other two grades.
For illustration, in a banking application for loans, the user grade is the front-end used by the client to stipulate the loan inside informations. The waiter grade can dwell of an RDBMS in which the information is stored. The concern grade lies between the other two grades and consists of concern regulations, such as the loan bound and the involvement rate charged to a client. If there is a alteration in the rate of involvement, merely the in-between grade constituent needs to be modified.
As the concern complexnesss increased, the concern grade became larger and unwieldy. This led to the development of n-tier architecture, where the concern services theoretical account was divided into smaller manageable units. N-tier architecture is besides called a multi-tier architecture.
In this architecture, one constituent near the client grade is responsible to make the client side proof and send the information to the presentation grade. Therefore, it is possible to maintain the UI-centric processing constituent on a computing machine near the client. The UI-centric processing constituent is responsible for treating the informations retrieved from and sent to the presentation grade. In add-on, you may hold another constituent near the database waiter to pull strings and formalize the information. You can maintain the data-centric processing constituents on another computing machine near the database waiter, so that you gain important public presentation benefits. Data-centric processing constituents are responsible for accessing the informations grade to recover, modify, and cancel informations to and from the database waiter.
The n-tier architecture consists of the undermentioned beds:
UI-centric processing constituents
Data-centric processing objects
The banking application, when further expanded, can stand for an illustration of naˆ‘tier architecture. The client grade would dwell of the user interface, which would include the user interface controls, such as signifiers, bill of fare, and toolbars. The waiter grade would dwell of data-handling including salvaging informations to the database waiter.
The concern logic would include the regulations and guidelines for different types of histories, involvement rates, fixed sedimentations, ATMs, and loan regulations. All of these would organize the in-between grade. However, there would be some regulations that need to be implemented both on the user interface and on the database. You can put these regulations either on the UI-centric processing constituents or data-centric processing constituents, based on the functionality.
Applications that follow multi-tier architecture can be used across assorted locations. For illustration, in Web applications, an application is stored on the Web waiter. The clients entree the application from any location through a browser. The clients make petitions to the Web waiter and receive responses.
The undermentioned figure shows the architecture of the Web applications.
The Architecture of the Web Applications
Depending on the type of concern regulations, the applications can be implemented on any of the grades, such as Web clients, Web waiter, or the database waiter.
To supply support to applications where users can direct petitions at the same time, the database waiter needs to be fast, dependable, and secure. SQL Server is one such complete database platform that provides a fast, dependable, and unafraid RDBMS. It besides helps in informations analysis with incorporate BI tools. The BI tools are used to fix studies that are analyzed farther to do efficient concern determinations.
SQL Server Components
SQL Server contains a figure of constituents. Each constituent provides specific services and support to the clients connected to the waiter.
The undermentioned figure displays the constituents of SQL Server.
The Components of SQL Server
As shown in the preceding figure, SQL Server consists of the following nucleus constituents:
A database engine provides support to hive away, question, procedure, and secure informations on a database waiter. It allows you to make and pull off database objects, such as tabular arraies, positions, stored process, and triggers. Apart from supplying support for informations direction, a database engine besides provides the following background services:
Service Broker: Provides support for asynchronous communicating between clients and the database waiter, enabling dependable question processing. The client application sends a petition to the database waiter and continues to work. These petitions are queued up at the waiter in instance the waiter is non available to treat the petition instantly. A Service Broker ensures that the petition is processed whenever the waiter is available.
The undermentioned figure shows the execution of Service Broker in the order processing system.
The Implementation of Service Broker in the Order Processing System
The preceding figure describes the illustration of the order processing system. The client applications are directing orders to the database waiter to come in the order inside informations. All these orders are placed in a waiting line, which is managed by the Service Broker.
Reproduction: Allows you to copy and administer informations and database objects from one database waiter to another. These waiters can be located at distant locations to supply fast entree to users at widely distributed locations. After retroflexing informations, SQL Server allows you to synchronise different databases to keep informations consistence. For illustration, the database waiters for your organisation might be located at different locations around the universe, but all the waiters store common informations. To guarantee that the informations in all the waiters is synchronized, you can implement informations reproduction. Reproduction follows the publisher/subscriber theoretical account. In this theoretical account, the alterations are sent out by one database waiter ( “ publishing house ” ) and are received by others ( “ endorsers ” ) .
The undermentioned figure depicts the reproduction procedure.
The Replication Process
In the preceding figure, articles are the database objects to be replicated. These articles are stored in a database called publication and are located on the publishing house waiter. The distributer waiter takes the publications from the publishing house waiter and distributes them to the endorsers.
Full-text hunt: Allows you to implement fast and intelligent hunt in big databases. It allows you to seek records incorporating certain words and phrases. You can seek for different signifiers of a specific word, such as ‘produce ‘ , ‘produces ‘ , or ‘production ‘ . In add-on, you can seek for equivalent word of a given word, such as ‘garment ‘ , ‘cloth ‘ , or ‘fabric ‘ .
Presentment services: Let you to bring forth and direct presentment messages to the users or decision makers about any event. For illustration, the database decision maker should be notified when a tabular array is created or deleted. The presentment messages can be sent to a assortment of devices, such as computing machines or nomadic devices. Notification service is a platform for developing and deploying extremely scalable presentment applications. It allows developers to construct presentment applications that send seasonably, personalized information updates, assisting to heighten client relationships. For illustration, a securities firm house sends stock and fund monetary values based on the client ‘s penchants.
Datas in different beginnings might be stored in different formats and constructions. Integration services allow you to garner and incorporate this varied information in a consistent format in a common database called the information warehouse. A information warehouse consists of incorporate databases, which can be a DBMS, text files, or level files. A information warehouse is similar to a physical warehouse that shops natural stuff or merchandises for farther distribution. The organisation does non hive away useless stuffs or merchandises in its warehouse because it costs money and affects the ability to acquire merchandises in and out of the warehouse. Similarly, a informations warehouse should non incorporate useless informations. The information should be meaningful so that it could be processed rapidly. A information warehouse is a big cardinal depository of informations that helps in decision-making.
See a telecommunications company, where the CEO notices that the frequence of cancellation of services by its clients in the past one twelvemonth has increased well. The company is unable to analyse the service penchants of the clients because information is scattered across disparate informations beginnings. These informations beginnings contain informations crossing two decennaries. In such a instance, a information warehouse can be implemented to incorporate two decennaries of historical informations from disparate informations beginnings. The integrated informations will supply a holistic position of the clients to the CEO.
SQL Server Integration Services ( SSIS ) Import and Export Wizard provides a series of duologues to assist you finish the procedure of choosing the information beginning, the finish, and the objects that will be transferred to make a information warehouse.
Data warehouses are designed to ease coverage and analysis. Enterprises are progressively utilizing informations stored in information warehouses for analytical intents to help them in doing speedy concern determinations. The applications used for such analysis are termed as BI applications. Data analysis aids in finding past tendencies and formulating hereafter concern determinations. This type of analysis requires a big volume of informations to make a consistent degree of trying.
In the telecommunications company scenario, with the aid of the analysis tools questioning on the information warehouse, the CEO can place the clients who are call offing their services. The company can so utilize this information to supply attractive offers to the identified clients and construct trueness. This sort of information analysis proves to be good to the endeavor in the long tally. The endeavor can retain its clients by offering trueness plans and strategies on the footing of analysis on the historical information.
See another illustration of a soft drink maker that uses informations of the past few old ages to calculate the measure of bottles to be manufactured in the current month. These prognosiss are based on assorted parametric quantities, such as the mean temperature during the last few old ages, buying capacity of the clients, age group of the clients, and past tendencies of ingestion. The demands for such an analysis include:
A big volume of informations
Historical informations, that is, informations stored over a period of clip
Therefore, analysis services help in informations analysis in a BI application. Microsoft SQL Server Analysis Services ( SSAS ) provide Online Analytical Processing ( OLAP ) for BI applications. OLAP arranges the information in the informations warehouse in an easy accessible format. This engineering enables informations warehouse to make on-line analysis of the informations.
Reporting services provide support to bring forth complete studies on informations in the database engine or in the information warehouse. These services provide a set of tools that help in making and pull offing different types of studies in different formats. Using these services, you can make centralised studies that can be saved to a common waiter. Reporting services provide secure and restricted entree to these studies.
Microsoft SQL Server Reporting Services ( SSRS ) aid in making Web-based studies based on the content stored in a assortment of informations beginnings. You can besides print these studies in different formats.
The undermentioned figure shows the use of the assorted SQL Server nucleus constituents in a BI application.
The Core Components of SQL Server
SQL Server Integration with the.NET Model
Microsoft SQL Server is integrated with the.NET Framework, as shown in the undermentioned figure.
Integration of SQL Server with the.NET Model
The.NET Framework is an environment used to construct, deploy, and run concern applications. These applications can be built in assorted programming linguistic communications supported by the.NET Framework. It has its ain aggregation of services and categories. It exists as a bed between the.NET applications and the underlying operating system.
SQL Server uses assorted services provided by the.NET Framework. For illustration, the presentment services constituent is based on the.NET Framework. This constituent uses the.NET Framework services to bring forth and direct presentment messages.
The.NET Framework is besides designed to do betterments in codification reuse, codification specialisation, resource direction, multilanguage development, security, deployment, and disposal. Therefore, it helps bridge the spread of interoperability between different applications.
The.NET Framework consists of the undermentioned constituents:
Development tools and linguistic communications
Base category library
Common Language Runtime ( CLR )
Development Tools and Languages
Development tools and linguistic communications are used to make the interface for the Windows signifiers, Web signifiers, and console applications. The tools include Ocular Studio and Visual C # Developer. The linguistic communications that can be used are Ocular Basic.NET, C # , or F # . These constituents are based on the.NET Framework base categories. These tools besides enable you to make database-related codifications and objects without exchanging to the SQL Server database engine. This enables you to work with database objects rapidly and easy.
Base Class Library
The.NET Framework consists of a category library that acts as a base for any.NET linguistic communication, such as Visual Basic, .NET, and C # . This category library is built on the object-oriented nature of the runtime. It provides categories that can be used in the codification to carry through a scope of common scheduling undertakings, such as twine direction, informations aggregation, database connectivity, and file entree. In add-on, it enables you to link with a database and generate books or make questions for accessing informations.
CLR is one of the most indispensable constituents of the.NET Framework. It provides an environment for the application to run. CLR or the runtime provides functionalities, such as exclusion handling, security, debugging, and versioning support to the applications.
Some of the characteristics provided by CLR are:
Automatic memory direction: Allocates and de-allocates memory to the application as and when required.
Standard type system: Provides a set of common informations types in the signifier of Common Type System ( CTS ) . This means that the size of whole number and long variables is the same across all scheduling linguistic communications.
Language interoperability: Provides the ability of an application to interact with another application written in a different scheduling linguistic communication. This besides helps maximise codification reuse.
Platform independency: Allows executing of a codification from any platform that supports the.NET CLR.
Security direction: Applies limitations on the codification to entree the resources of a computing machine.
CLR can host a assortment of linguistic communications. It offers a common set of tools across these linguistic communications, guaranting interoperability between the codifications. The codification developed with a linguistic communication compiler that targets CLR is called a managed codification.
Alternatively, the codification that is developed without sing the regulations and demands of the common linguistic communication runtime is called unmanaged codification. Unmanaged codification executes in the common linguistic communication runtime environment with minimum services. For illustration, unmanaged codification may run with limited debugging and without the refuse aggregation procedure.
With CLR integrating in SQL Server, you can implement programming logics that involve complex operations in the database by utilizing the plans written in any of the.NET-supported linguistic communications. CLR integrating allows you to make objects in a
.NET-supported linguistic communication and implant these objects in the database. You can implant the.NET codification in database objects such as stored process, map, or trigger. Such a database object is called a managed database object.
Features of SQL Server
The constituents of SQL Server aid better the database direction and developer productiveness by the undermentioned characteristics of SQL Server:
Built-in support for Extensible Markup Language ( XML ) information: Allows you to hive away and pull off XML informations in variables or columns of the XML informations type. The XML characteristic of SQL Server enables you to compose codification to recover informations from the database in the signifier of XML. In add-on, it allows you to read an XML papers and hive away the XML informations in the database.
CLR integrating: Allows you to utilize the CLR characteristics of.NET Framework in the SQL Server database. It enables you to utilize the codification written in any of the.NET supported linguistic communications for implementing complex scheduling logics in the database. For illustration, you need to compose a codification for the confirmation of the recognition card figure entered by the user. It will be complex to compose the codification for the confirmation of the recognition card figure in T-SQL. However, the same codification can be written efficaciously utilizing a.NET scheduling linguistic communication. Therefore, you can compose the codification in a.NET scheduling linguistic communication and usage that codification in SQL Server to verify the recognition card information.
Scalability: Allows you to administer the information in big tabular arraies into several filegroups. This enables SQL Server to entree all the filegroups at the same time and recover the informations rapidly. This makes the database scalable and helps better the public presentation of questions.
Service-oriented architecture: Provides distributed, asynchronous application model for large-scale applications. This allows the database clients to direct petitions to the database server even if the waiter is non available to treat the petition instantly.
Support for Web services: Allows you to supply direct entree to the information from the Web services by implementing the HTTP end points. For illustration, gross revenues executives of an organisation demand to entree the information on the database waiter through their Personal Desktop Assistant ( PDA ) devices. However, supplying direct entree from a PDA device to the database waiter involves a high cost. Therefore, organisation can implement Web services through which each gross revenues executive can log the gross revenues inside informations online from anyplace utilizing any device.
High degree of security: Implements high security by implementing policies for log on watchwords. Administrators can besides pull off permissions on database objects granted to different users.
High handiness: Ensures that the database waiter is available to all users at all times. This reduces the downtime of the waiter. In SQL Server, high handiness is implemented with the aid of database mirroring, failover bunch, and database snapshots.
Support for informations migration and analysis: Provides tools to migrate informations from different informations beginnings to a common database. In add-on, it allows constructing the information warehouse on this information that can back up BI applications for informations analysis and decision-making.
Intellisense: Provides the characteristic of car completion of codification written to make or pull strings database objects in the Query Editor window.
Policy-based direction: Used to specify a set of policies for configuring and pull offing SQL Server. For illustration, you can specify a policy to put a appellative convention for tabular arraies and stored processs. When a user tries to make a tabular array, the tabular array name must map with the calling convention defined in the policy, else an mistake will be raised.
Resource governor: Used to pull off the work load of SQL Server by apportioning and pull offing the waiter resources, such as CPU clip and memory. The resource pool represents the waiter resource. You can stipulate the lower limit and maximal values of the CPU and memory use in a resource pool. These resources are used for running and executing assorted assigned undertakings in SQL Server.
As a database developer, you need to pull off the database to hive away, entree, and modify informations. SQL is the nucleus linguistic communication used to execute these operations on the information. SQL, pronounced as “ subsequence ” , is a linguistic communication that is used to pull off informations in an RDBMS. This linguistic communication was developed by IBM in the 1970s. It follows the International Organization for Standardization ( ISO ) and American National Standards Institute ( ANSI ) criterions.
Most database systems have created customized versions of the SQL linguistic communication. For illustration, Transact-SQL ( T-SQL ) is a scripting linguistic communication used in SQL Server for programming. The applications may hold different user interfaces but have a common manner to pass on with SQL Server by directing T-SQL statements to the waiter.
The SQL statements can be divided into the undermentioned classs:
Data Definition Language ( DDL ) : Is used to specify the database, informations types, constructions, and restraints on the information. Some of the DDL statements are:
CREATE: Used to make a new database object, such as a tabular array.
ALTER: Used to modify the database objects.
Drop: Used to cancel the objects.
Data Manipulation Language ( DML ) : Is used to pull strings the informations in database objects. Some of the DML statements are:
Insert: Used to infix a new information record in a tabular array.
Update: Used to modify an bing record in a tabular array.
DELETE: Used to cancel a record from a tabular array.
Data Control Language ( DCL ) : Is used to command the informations entree in the database. Some of the DCL statements are:
Grant: Used to delegate permissions to users to entree a database object.
Revoke: Used to deny permissions to users to entree a database object.
Data Query Language ( DQL ) : Is used to question informations from database objects. SELECT is the DQL statement that is used to choose informations from the database in different ways and formats.
SQL is non a case-sensitive linguistic communication. Therefore, you can compose the statements in any instance, small letter or capital. For illustration, you can utilize the SELECT statement in small letter as ‘select ‘ or in title instance as ‘Select ‘ .
Merely a minute:
Which of the undermentioned characteristics of SQL Server allows the developers to implement their scheduling logic in any linguistic communication supported by the.NET Framework?
Support for informations migration
