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.
