Abstract:
An apparatus, system, and method are disclosed for logging operations for a database. An operation event module detects an operation on a record in a database table. A translation module creates a changed field bit field, one or more operation time bit fields, and a user bit field. The translation module creates the changed field bit field by encoding indicators of one or more fields of the record that the operation is configured to change, creates the one or more operation time bit fields by encoding time information for the operation, and creates the user bit field by encoding information of a user associated with the operation. A consolidation module packs at least the changed field bit field, the one or more operation time bit fields, and the user bit field into a single bit array. A log module stores the bit array in a change log.
