Abstract: Systems, methods, and other embodiments associated with concurrently maintaining separate versions of records in an electronic database are described. In one embodiment, a method includes enabling the electronic database to concurrently store separate versions of a record by using a set of system columns to maintain the separate versions together in the electronic database and provide access to each of the separate versions in isolation from one another. The example method may also include, in response to identifying a change request to modify the record, generating an additional version of the record in the electronic database by adding the additional version into the electronic database with a new row identifier in a row identifier column and a row identifier from the record stored in the source column to uniquely identify the additional version as a version of the record and avoid conflicts between multiple versions of the record.
