What is SQL Server 2000? (3) Microsoft SQL Server 2000 is designed to work effectively as: A central database on a server shared by many users who connect to it over a network. A desktop database that services only applications running on the same desktop

SQL Server Services Consists of 3 Services: MSSQLServer Data & query processing SQL Server Agent Scheduled jobs & alerts Microsoft Distributed Transaction Coordinator The Microsoft Distributed Transaction Coordinator (MS DTC) is a transaction manager that allows client applications to include several different sources of data in one transaction. MS DTC coordinates committing the distributed transaction across all the servers enlisted in the transaction.

SQL Server Tools Enterprise manager MMC application that provides easy visual control over numerous common DBA and developer tasks SQL Server Profiler Service Manager Query Analyzer Enter queries, browse objects on the server, view execution paths, etc. Numerous other tools

Database (master) The master database records all login accounts and all system configuration settings. master is the database that records the existence of all other databases, including the location of the database files.

Databases (msdb,distribution,model) The msdb database is used by SQL Server Agent for scheduling alerts and jobs, and recording operators. The distribution database is used for replication. The distribution database is used for replication. The model database is used as the template for all databases created on a system.

Database (tempdb) tempdb holds all temporary tables and temporary stored procedures. It also fills any other temporary storage needs such as work tables generated by SQL Server. tempdb is re-created every time SQL Server is started so the system starts with a clean copy of the database.

System Tables System tables store information (metadata) about the system and database objects Database catalog stores metadata about a specific database System catalog stores metadata about the entire system and all other databases

User Tables Defined by DBA or developer to hold application specific information Created either through Transact-SQL script or Enterprise Manager System catalog is updated to hold meta-information about the user tables

CREATE TABLE Northwind.dbo.OrderHistory.
