To solve this problem, keep the database design document information maintainability, uniqueness and ease of use. The following proposed solutions for software development companies and personal use, to maintain a database of information.
Background: the use of extended attributes function sqlserver database have
1, fn_listextendedproperty return extended property values of database objects.
2, sp_addextendedproperty the new extended attributes added to the database objects. If the property already exists, the process fails.
3, sp_updateextendedproperty update values in existing extended attribute.
