A SQL Server 2005 database can be detached by using: SQL Server Management Studio T-SQL To move a database from an instance of SQL Server, you can detach it from one instance and attach it to another instance. You can attach a database by using: SQL Server Management Studio T-SQL The process of retrieving data from a backup and applying transaction log to the data is called as restoring. Slide 3 Installing Windows XP Professional Using Attended Installation Slide 3 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 7 Knowledge Byte (Contd.) The process of rolling forward uncommitted transactions, if any, and bringing the database online is known as recovery. In a restore process, the logged changes are applied to the data in a database to retrieve the data on time. This process is known as rolling forward and the set of data restored is known as roll forward set. Each restore scenario is implemented by using one or more restore steps (operations), called a restore sequence. A restore operation is a multiphase process. The possible phases of a restore process are: Data copy phase Redo phase Undo phase ¤NIIT Instructor Inputs 7.5 Slide 4 Installing Windows XP Professional Using Attended Installation Slide 4 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 7 Best Practices While creating your own database objects, ensure that you do not create the database objects in the system databases like master database. While moving master database and log files to another location, ensure that you also move the Resource database to the same location. While restoring the Resource database you must be careful not to overwrite the current Resource database with an out- of-date or potentially insecure version of Resource database. Slide 5 Installing Windows XP Professional Using Attended Installation Slide 5 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 7 Best Practices (Contd.) The size of tempdb can affect the performance of a system. If the size of the tempdb is less than the requirement of the server, it would have an impact on the performance of the server. A good practice is to increase the size of tempdb. It is not a good idea to shrink a database if the database has frequent updations. In these cases, shrinking a database is a wasted operation. 7.6 Instructor Inputs ¤NIIT Slide 6 Installing Windows XP Professional Using Attended Installation Slide 6 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 7 Tips and Tricks Backup the master database after performing the following operations: Creating, modifying, or dropping a database Changing server and database configuration values Modifying or adding logon accounts After restoring a backup of mssqlsystemresource.mdf, it is a good practice to reapply any subsequent updates. After you add or delete files in a database, create a database backup immediately. If you have to create multiple secondary files in your database, create them in a separate filegroup. Do not put the Resource database in either compressed or encrypted NTFS file system folders. Slide 7 Installing Windows XP Professional Using Attended Installation Slide 7 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 7 Can you change the owner of the master database? You cannot change the owner of master database as it is owned by dbo. FAQs ¤NIIT Instructor Inputs 7.7 Slide 8 Installing Windows XP Professional Using Attended Installation Slide 8 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 7 Can master database be dropped? No, you cannot drop master database as it is a system database. FAQs (Contd.) Slide 9 Installing Windows XP Professional Using Attended Installation Slide 9 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Collaborate Session 7 While creating objects in a database if user does not specify the filegroup, which filegroup are objects assigned to? The objects are by default assigned to default filegroup. The primary filegroup is the default filegroup. FAQs (Contd.) 7.8 Instructor Inputs ¤NIIT Slide 10 Installing Windows XP Professional Using Attended Installation Slide 10 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 7 What are the three types of files used to store a database? Which of these files are must for a database? The three types of files to store a database are primary files, secondary files, and transaction files. A database must have a primary file and atleast one transaction log file. FAQs (Contd.) Slide 11 Installing Windows XP Professional Using Attended Installation Slide 11 of 16 Ver. 1.0 Querying, Managing, and Administering Databases Using SQL Server 2005 Colla borate Session 7 Can transaction log files be a part of any filegroup?
