Abstract
A device maintains, in a database, a plurality of data items, each data item of the plurality of data items being associated with a respective category. The device associates, in the database, a first counter value with each data item, the first counter value indicating a number of times the respective category has been deleted from the database at a time when the data item was stored in the database. The device associates, in the database or another database, a second counter value with the respective category, the second counter value indicating a current value for a number of times the respective category has been deleted from the database. The device selectively deletes, from the database, one or more data items of the plurality of data items from the database based on the first counter values and the second counter value.
