Dynamometers
Scheduled tasks let user automate processes that run on regular or predictable cycles. User can schedule New GPR557 Engine
administrative tasks, such as cube processing, to run during times of slow business activity. User can also Dynamometer Diesel
determine the order in which tasks run by creating job steps within a SQL Server Agent job. E.g. back up database, Dynamometers

28. What are the advantages of using Stored Procedures? from Traditional to
Modern Wood & Metal
bases
www.SuperiorModel.com
1. Stored procedure can reduced network traffic and latency, boosting application performance.
2. Stored procedure execution plans can be reused, staying cached in SQL Server's memory, reducing server
overhead.
3. Stored procedures help promote code reuse.
4. Stored procedures can encapsulate logic. You can change stored procedure code without affecting clients.
5. Stored procedures provide better security to your data.
29. What is a table called, if it has neither Cluster nor Non-cluster Index? What is it used for?
Unindexed table or Heap. Microsoft Press Books and Book on Line (BOL) refers it as Heap. A heap is a table that
does not have a clustered index and, therefore, the pages are not linked by pointers. The IAM pages are the only
structures that link the pages in a table together. Unindexed tables are good for fast storing of data. Many times it
is better to drop all indexes from table and then do bulk of inserts and to restore those indexes after that.
30. Can SQL Servers linked to other servers like Oracle?
SQL Server can be linked to any server provided it has OLE-DB provider from Microsoft to allow a link. E.g. Oracle
has an OLE-DB provider for oracle that Microsoft provides to add it as linked server to SQL Server group.
