Transactional replication with updating subscribers
A trigger that contains data modification logic within itself is called a nested trigger.
A simple view can be thought of as a subset of a table.
In relational database design, the process of organizing data to minimize redundancy.
Cumulative Update; Cumulative updates contain the bug fixes and enhancements–up to that point in time–that have been added since the previous Service Pack release and will be contained in the next service pack release.
Interdependencies among these tables are expressed by data values rather than by pointers. An RDBMS has the capability to recombine the data items from different files, providing powerful tools for data usage.
Database normalization is a data design and organization process applied to data structures based on rules that help build relational databases.
Table scans are sometimes unavoidable, but on large tables, scans have a terrific impact on performance.
is a special type of index that reorders the way records in the table are physically stored. The leaf nodes of a clustered index contain the data pages.SQL Server CUs are certified to the same levels as Service Packs, and should be installed with the same level of confidence.976761 FIX: Error message when you perform a rolling upgrade in a SQL Server 2008 cluster : "18401, Login failed for user SQLTEST\Agent Service.
