Abstract: A method and systems are provided for managing database data. A data repository stores existing immediate mode data in the form of immediate mode database records. Transaction mode database records for modifying and adding to the immediate mode records are created and stored, with the transaction mode records being organized into transactions. Each transaction includes a definition, such as a transaction definition record, and transaction mode records are associated with a transaction using a field in each transaction mode record including a reference to a transaction. A transaction can be posted, causing values stored in the transaction mode records associated with the transaction to be used to create added or modified immediate mode records. Transactions can also be used in operations providing views to show the effects of the transaction mode records, or to create data structures for export.
