Overview

To comply with data protection regulations, storage restrictions, or other requirements, you might need to delete data from the Information Store. i2 Analyze provides mechanisms for doing so. The mechanism that you choose depends on how the records were created in the Information Store and your reason for deleting them.

There are two ways to delete records from the Information Store:

• Some of the records in the Information Store are created and uploaded through Analyst's Notebook. If a user deletes a record that they or a colleague uploaded, it becomes unreachable for all users, but remains in the Information Store. You can arrange to delete these soft-deleted records permanently, either automatically or on demand.

• For all records in the Information Store, you can write identifying rules that target them for deletion individually or as a group. This approach deletes records no matter how they were originally created or what their current state is.

It is common to all record deletion that deleting an entity record forces i2 Analyze to delete the link records that are attached to that entity. A link must always have two ends. If one end is deleted, the link is automatically deleted as well.

It is also common to both of these ways for deleting records from the Information Store that the procedure is permanent. If you might need to recover the deleted data in future, ensure that you have a backup plan in place before you begin.

Note: The demands of synchronizing with the contents of an external source can also require you to delete data from the Information Store. In that situation, you can reflect deleted data in an external source by using the same ingestion pipeline that you use to reflect creation and modification.
