Managing Data Sources

You use the Profiles Schema Manager to modify the data sources you created. For example, you make changes in the data store that your profile properties map when you have to modify or delete obsolete data objects and data members. Alternatively, you use the Profiles Schema Manager when you create a new data source and want to delete the old data source. You can change and delete data sources, data objects, and data members.

Consider the following restrictions about modifying your data sources:

  • You can add partitions only to a data source that you have never partitioned. You must add partitions to a source before you use it to store data. If you partition a source that contains data, you will loose the existing data.

  • You cannot delete data source partitions, but you can modify them. You must be careful when you modify the partitions of a data source that contains data, because modifications can cause data loss or corruption.

  • When you delete a data source, you cannot recover it. You also delete all the data objects and data members associated with the data source. You must re-map the profile definitions mapped with the deleted data members to the data storage with existing data members.

  • When you delete a data object, you cannot recover it. You also delete all the data members associated with the deleted data object. You must re-map the profile definitions mapped with the deleted data members to the data storage with existing data members.

  • When you delete a data member, you cannot recover it. You must re-map the profile definitions mapped with the deleted data member to the data storage with an existing data member.
