Microsoft SQL Server Databases

Go Up to Databases

Databases are a collection of tables, or a collection of index spaces and tablespaces. The goals of a database system are straightforward but challenging. In general, a database aims to manage large amounts of data in a multi-user environment. It should achieve high performance while letting many users access the same information concurrently without compromising data integrity. A database also must protect against unauthorized access and provide reliable solutions for failure recovery.

Note: Microsoft SQL Server recommends that you do not create any user objects, such as tables, views, stored procedures, or triggers, in the master database. The master database includes the system tables that store the system information used by SQL Server, such as configuration option settings.
