Ola Hallengren’s SQL Server Maintenance Solution – Installation and SQL Server Backup solution

December 5, 2017 by

Database administrators tend to use various scripts or applications, to make the daily SQL Server database maintenance task easier.

Some more experienced administrators prefer to design and use their own scripts for these tasks. The scripts are usually designed to fit the requirements imposed by the specific environment. After the scripts are thoroughly tested, they often get included in a maintenance plan, or SQL Server agent job to automate their execution. Such solution is usually optimal for some demanding environments like high traffic servers or databases that are still in development. Designing these solutions usually take time, and require an experienced DBA skilled in T-SQL or PowerShell scripting.

Optimize NULL values storage consumption using SQL Server Sparse Columns

August 29, 2016 by

SQL Server 2008 introduces a new column attribute that is used to reduce the storage consumed by NULL values in the database tables. This feature is known as Sparse Columns.
