Maatkit offers a whole slew of tools for doing backup and restore, finding tables, monitoring your database server and many other database administration tasks you may not have even thought of.
SQL Server Integration Services' primary purpose is to serve as a database development platform. As such, it is subject to standard best practices of software programming, which among other recommendations, advocate reusability. Realizing this objective in SSIS frequently involves the use of variables. Their characteristics and most common usage scenarios will be the primary subject of our presentation.
You've taken a quick look, and decided that Sybase ASE Cluster Edition is right for you. Managing the POC requires a great deal of forethought and planning. Jeffrey Garbus shares some best practices to get you started.
