Claim 11:
12. A computer-implemented method, comprising:
in response to a request to delete a group of data associated with a user account from a group of database components, analyzing, by a system having a processor and a memory, a group of rules and information associated with the user account, wherein the group of rules is applicable to the group of database components and relates to data deletion and data retention, and wherein the information comprises an account status associated with the user account;
based on the analyzing of a first rule of the group of rules and the information, determining, by the system, a first permissibility status for deletion of a first portion of the group of data from the group of database components, the first permissibility status indicating that the first portion of the group of data is eligible for deletion;
based on the analyzing of a second rule of the group of rules and the information, determining, by the system, a second permissibility status for deletion of a second portion of the first portion of the group of data from the group of database components, the second permissibility status indicating that the second portion of the first portion of the group of data is ineligible for deletion;
based on the determined permissibility status, automatically deleting a third portion of the group of data, the third portion comprising all data in the first portion that are not in the second portion;
in response to the erasure of the third portion of the group of data, generating mask data corresponding to the third portion of the group of data; and
replacing the erased third portion in the group of database components with the corresponding mask data, the mask data configured to maintain a validity of a link to the third portion.
