Abstract:
A method of updating a database, including data records, to accord with an updated schema. The method includes obtaining, at a portable electronic device, the updated schema associated with the database. If a field is deleted in the updated schema, the data records are updated by deleting the field from each of the data records. An update command is transmitted from the portable electronic device for updating the database schema for a corresponding backup database at a server.
