Embodiments disclosed are directed to implementing an immutable database. Several embodiments are directed to an architecture for implementing the immutable database as a data processing system with a real-time interface for buffering a plurality of transactions and a bitemporal ledger for storing the plurality of transactions and a processor. New transactions may be appended to the transaction to the plurality of transactions and processed in a temporal order which includes identifying a sequence of transactions in the bitemporal ledger associated with the transaction and incorporating the transaction into the sequence of transactions in the bitemporal ledger according to temporal metadata associated with the transaction to form an updated sequence of transactions.

Architecture of immutable database for bitemporal analysis

Embodiments disclosed are directed to an immutable database in a data processing system for tracking a data state of the data processing system using multiple timelines or temporal sequences representing events occurring in the data processing system. The immutable database may maintain a current temporal sequence representing an existing data state of the data processing system and generate alternate temporal sequences representing an alternate data state of the data processing system. The alternate temporal sequence may be used to test retroactive events that are intended to replace or correct events that occurred in the current temporal sequence.

Immutable database for processing retroactive and historical transactions using bitemporal analysis

Embodiments disclosed are directed to an immutable database with a bitemporal ledger for storing transactions in timelines for maintaining a record of all events and resources within the system. The bitemporal ledger may store a sequence of transactions which include a plurality of transactions previously received by the data processing system in a temporal sequence up to a current time. A new transaction is received and may be appended to the sequence of transactions based on temporal metadata associated with the transaction are received, The temporal metadata may include a valid-from time and a created-at time.
