Quick intro to SQL Server 2008

What is SQL Server 2008 RDBMS?

SQL Server 2008 is primarily thought of as a Relational Database Management System (RDBMS). It is certainly that, but it is also much more.SQL Server 2008 can be more accurately described as an Enterprise Data Platform. It offers many new features and even more enhanced or improved features from previous editions of the product. In addition to traditional RDBMS duty, SQL Server 2008 also provides rich reporting capabilities, powerful data analysis, and data mining, as well as features that support asynchronous data applications, data-driven event notification, and more.

Database Engine

The Database Engine is the primary component of SQL Server 2008. It is the Online Transaction Processing (OLTP) engine for SQL Server, and has been improved and enhanced tremendously in this version. The Database Engine is a high-performance component responsible for the efficient storage, retrieval, and manipulation of relational and Extensible Markup Language (XML) formatted data.

SQL Server 2008’s Database Engine is highly optimized for transaction processing, but offers exceptional performance in complex data retrieval operations. The Database Engine is also responsible for the controlled access and modification of data through its security subsystem. SQL Server 2008’s Database Engine has many major improvements to support scalability, availability, and advanced (and secure) programming objects.

SQL Server database : Regular maintenance

If you are a DBA it is very important for you to know maintenance plan in SQL Server. Generally we use SQL Enterprise Manager to perform regular maintenance of SQL database.

The information below does not cover everything you can do to maintain your SQL database in SQL Enterprise Manager. Before you must See your SQL documentation for details on what else you can do to maintain your database.

Backing up the transaction log is not compatible with simple recovery. If you have multiple databases with different recovery models, you can create separate database maintenance plans for each recovery model. In this way you can include a step to backup your transaction logs only on the databases that do not use the simple recovery mode.

Change recovery model to simple

Simple recovery mode is recommended because it prevents the transaction logs from swelling. In simple recovery, once a checkpoint is complete, the transaction logs for the time before the checkpoint are dropped from the active database. A checkpoint automatically occurs when the backup is made. We recommend having a database maintenance plan that performs a backup of the ePO database, together with "Simple Recovery". In this way, once a backup is successfully created, the portion of the transaction log in the active database will be dropped as it is no longer needed since a backup file exists.
