Extension Ledger

摘要

A system stores financial accounting data in a Base ledger, together with overlying extension ledger(s). An engine receives both generic financial data, and financial data utilized for specific purposes. Utilizing a mapping table the engine stores in an underlying Base ledger, the generic financial data (e.g., a fixed asset acquisition). The engine stores in overlying extension ledgers, specific financial data (e.g., a linear asset depreciation and/or an declining balance method of asset depreciation) derived from that generic data. This reduces memory footprint by persisting the generic data in one location only. The stored data may be read utilizing dataviews combining data from Base and extension ledgers. A recursive algorithm may evaluate chain(s) of ledgers. Embodiments may be particularly suited to store in the Base ledger generic financial data common to multiple accounting principles (e.g., GAAP, IFRS), and store in extension ledger(s) the associated financial data specific to those accounting schemes.

1. A computer-implemented method comprising:
an engine receiving generic financial data, first specific financial data associated with the generic financial data, and second specific financial data associated with the generic financial data; the engine writing the generic financial data to a base ledger; the engine writing the first specific financial data to a first extension ledger, and writing the second specific financial data to a second extension ledger, the first extension ledger and the second extension ledger linked to the base ledger according to a mapping table; the engine referencing the mapping table to read from the first extension ledger, a first report comprising the generic financial data and the first specific financial data; and the engine referencing the mapping table to read from the second extension ledger, a second report comprising the generic financial data and the second specific financial data.
