A method performed by a processor for an individual to maintain a database including a core and an extension, wherein the core contains core tables including general data and the extension contains extension tables including specific data, the method comprising: comparing general data from at least one core table with specific data from at least one extension table, wherein the at least one core table and the at least one extension table have the same primary keys and the specific data extends from the general data; receiving an input from the individual for modifying the database; modifying the core using the received input; modifying the extension to reflect the modifying of the core; automatically adding a new entry to the at least one extension table when a first entry in the at least one core table does not correspond to any entry in the at least one extension table; and automatically deleting all entries from the at least one extension table that are identified, based on the comparison, as not corresponding to any entry in the at least one core table.
