As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications—which may run either on the same computer or on another computer across a network SQL Server Components SQL Server works in client-server architecture, hence it supports two types of components − (a) Workstation and (b) Server. Workstation components are installed in every device/SQL Server operator’s machine. These are just interfaces to interact with Server components. Example: SSMS, SSCM, Profiler, BIDS, SQLEM etc. Server components are installed in centralized server. These are services. Example: SQL Server, SQL Server Agent, SSIS, SSAS, SSRS, SQL browser, SQL Server full text search etc. Instance of SQL Server An instance is an installation of SQL Server. An instance is an exact copy of the same software. If we install 'n' times, then 'n' instances will be created. There are two types of instances in SQL Server a) Default b) Named. Only one default instance will be supported in one Server. Multiple named instances will be supported in one Server. Default instance will take the server name as Instance name. Default instance service name is MSSQLSERVER. 16 instances will be supported in 2000 version. 50 instances will supported in 2005 and later versions. Advantages of Instances To install different versions in one machine. To reduce cost. To maintain production, development, and test environments separately. To reduce temporary database problems. To separate security privileges. To maintain standby server. #sql #sqlserver #sqla #sqlqueries #sqltraining #sqlservertutorial #sqlservermanagementstudio
