Microsoft® SQL Server 2012 Unleashed

Categories

Microsoft recognized that although you may want to implement a set of rigid standards for your internal SQL Server development or deployments, your enterprise may have to host third-party software that does not follow your standards. Although your internally developed user databases will subscribe to your own policies, the third-party user applications will subscribe to their own categories. To provide flexibility, you can select which policies you want a table, database, or server to subscribe to and group them into groups called categories, and then have a database subscribe to a category and unsubscribe from a group of other policies if necessary. A policy can belong to only one policy category.
