Title: (EN) SYSTEM AND METHOD FOR RECORDING TRANSACTIONS
(FR) SYSTEME ET PROCEDE D'ENREGISTREMENT DE TRANSACTIONS
Abstract:
(EN) Recording transactions using a chronological list superimposed on an indexed list. A transaction log of transaction entries is maintained as a chronological list superimposed on an indexed list. Preferably, each transaction entry includes a transaction descriptor field, a time stamp field, a chronological list pointer field and an indexed list pointer field. A first chronological list pointer points to the oldest transaction entry in the transaction log and a last chronological list pointer points to the latest transaction entry in the transaction log. The chronological list pointer field of a transaction entry points to the next oldest transaction entry. The indexed list includes a number of indexed list entry pointers. Each indexed list entry pointer corresponds to an index and points to a transaction entry with the same index. Th indexed list pointer field of a transaction entry points to another transaction entry with the same index. Adding a transaction entry to the transaction log or deleting a transaction entry from the transaction log includes updating the chronological list pointers and the indexed list pointers.
