Chapter 1: What is SQL Server?Introduction, History, Editions,InstancesWhat is SQL Server?SQL Server is a relational database management system (RDBMS) developedby Microsoft. It is primarily designed and developed to compete with MySQLand Oracle database.SQL Server supports ANSI SQL, which is the standard SQL (Structured QueryLanguage) language. However, SQL Server comes with its ownimplementation of the SQL language, T-SQL (Transact- SQL).T-SQL is a Microsoft propriety Language known as Transact-SQL. It providesfurther capabilities of declaring variable, exception handling, storedprocedure, etc.SQL Server Management Studio (SSMS) is the main interface tool for SQLServer, and it supports both 32-bit and 64-bit environments.History SQL ServerMicrosoft and Sybase released version 1.0 in 1989. However, the partnershipbetween these two ended in the early 1990s. Microsoft maintainedownership rights to the name SQL Server. Since the 1990s,

subsequent versions of SQL Server have been released including SQL Server2000, 2005, 2008, 2012, 2014, 2016 and 2017.SQL Server EditionsFollowing editions are availableSQL Server Enterprise: It is used in the high end, large scale and missionCritical business. It provides High-end security, Advanced Analytics, MachineLearning, etc.SQL Server Standard: It is suitable for Mid-Tier Application and Data marts. Itincludes basic reporting and analytics.SQL Server WEB: It is designed for a low total-cost-of-ownership option forWeb hosters. It provides scalability, affordability, and manageabilitycapabilities for small to large scale Web properties.SQL Server Developer: It is similar to an enterprise edition for the nonproduction environment. It is mainly used for build, test, and demo.SQL Server Express: It is for small scale applications and free to use.MS SQL Server as Client-Server ArchitectureLet's have a look at the below early morning conversation between Momand her Son, Tom.

Brainstorm:Ask your brain .!!! "Can you map, who is CLIENT and who the SERVER is?"The most certain reply would be - "I am pretty smart in that and . Son is aCLIENT as he is requesting for a cup of coffee and Mother, who is CAPABLE ofpreparing coffee, is a SERVER."Here, Tom is requesting his mother, a cup of coffee. Finally, mom does someprocessing with Milk, coffee, sugar and prepare coffee to serve it hot.Analogy: MS SQL SERVER architecture.A CLIENT is an application that sends requests to the MS SQL SERVERinstalled on a given machine. The SERVER is capable of processing inputdata as requested. Finally, respond with PROCESSED OUTPUT DATA as aresult.

Key Components and Services of SQL ServerDatabase Engine: This component handle storage, Rapid transactionProcessing, and Securing Data.SQL Server: This service starts, stops, pauses, and continues an instance ofMicrosoft SQL Server. Executable name is sqlservr.exe.SQL Server Agent: It performs the role of Task Scheduler. It can be triggeredby any event or as per demand. Executable name is sqlagent.exe.SQL Server Browser: This listens to the incoming request and connects to thedesired SQL server instance. Executable name is sqlbrowser.exe.SQL Server Full-Text Search: This lets user running full-text queriesagainst Character data in SQL Tables. Executable name isfdlauncher.exe.SQL Server VSS Writer: This allows backup and restoration of data files whenthe SQL server is not running. Executable name is sqlwriter.exe.SQL Server Analysis Services (SSAS): Provide Data analysis, Data mining andMachine Learning capabilities. SQL server is integrated with R and Pythonlanguage for advanced analytics.Executable name is msmdsrv.exe.SQL Server Reporting Services (SSRS): Provides reporting features anddecision-making capabilities. It includes integration with Hadoop. Executablename is ReportingServicesService.exe

SQL Server Integration Services (SSIS): Provided Extract- Transform and Loadcapabilities of the different type of data from one source to another. It can beview as converting raw information into useful information. Executable nameis MsDtsSrvr.exeSQL Server InstancesSQL Server allows you to run multiple services at a go, with each servicehaving separate logins, ports, databases, etc. These are divided into two:Primary instancesNamed instances.There are two ways through which we may access the primary instance.First, we can use the server name. Secondly, we can use its IP address.Named instances are accessed by appending a backslash and instance name.For example, to connect to an instance named xyx on the local server, youshould use\xyz. From SQL Server 2005 and above, you are allowedto run up to 50 instances simultaneously on a server.Note that even though you can have multiple instances on the same server,only one of them must be the default instance while the rest must benamed instances. One can run all the instances concurrently, and eachinstance runs independent of the other instances.Importance of SQL Server InstancesThe following are the advantages of SQL Server instances:

1. For installation of different versions on one machineYou can have different versions of SQL Server on a single machine. Eachinstallation works independently from the other installations.2. For cost reductionInstances can help us reduce the costs of operating SQL Server, especially inpurchasing the SQL Server license. You can get different services fromdifferent instances, hence no need for purchasing one license for all services.3. For maintenance of development, production and testenvironments separatelyThis is the main benefit of having many SQL Server instances on a singlemachine. You can use different instances for development, production andtest purposes.4. For reducing temporary database problemsWhen you have all services running on a single SQL Server instance, thereare high chances of having problems with the problems, especiallyproblems that keep on recurring. When such services are run on differentinstances, you can avoid having such problems.5. For separating security privilegesWhen different services are running on different SQL Server instances, youcan focus on securing the instance running the most sensitive service.6. For maintaining a standby server

A SQL Server instance can fail, leading to an outage of services. This explainsthe importance of having a standby server to be brought in if the currentserver fails. This can easily be achieved using SQL Server instances.Summary:SQL Server is defined as a relational database management system(RDBMS) developed by MicrosoftT-SQL means Transact-SQL, a propriety Language by Microsoft Microsoftand Sybase released version 1.0 in 1989Various Editions of SQL Server are Enterprise, Standard, Web, Developer,and ExpressCritical components of SQL Server are Database Engine, SQL Server, SQLServer Agent, SQL Server Browser, SQL Server Full- Text Search, etc.You can run multiple instances of SQL Server the same on the samemachine.

Chapter 2: How to Download andInstall SQL ServerPre-RequisitesPrincipally, MS SQL server requires:.Net Framework,1GB of recommended memory, and NTFS system.How to download SQL Server SetupStep 1) Go to URL: https://www.microsoft.com/en-in/sql-server/sql- serverdownloadsMicrosoft provides two specialized free editions to work on MS SQL server:1. Developer – It has all feature which MS SQL server offers but wecannot use it in production. From the learning perspective, is it anideal candidate to start.2. Express: This is also a free version but with the limited set offeatures with no business intelligence applications.We will select the Developer edition for installation.

Step 2) Click on "Download now"We will get set up as 'SQLServer2017-SSEI-Dev.exe'.How to Install SQL ServerStep 1) Double click on "SQLServer2017-SSEI-Dev.exe". Below screen willappear with three options: Basic, Custom and Download files.
