Design Overview
In order to make the rollup and extraction of the stock ledger transaction data flexible, this program moves the data on the TRAN_DATA to the IF_TRAN_DATA staging table. This will enable the processes that are writing records to TRAN_DATA to continue in a seamless manner, whereas the processes that rolls the data up to a different level or extract the data to external systems can work without affecting batch timetables.
This process will be achieved by locking the TRAN_DATA table and moving all of the data to the staging table. The original TRAN_DATA table will be emptied and the lock on the table will be released. Before this processing occurs, the staging table will first be emptied to ensure that data is not processed twice. Because the data on the TRAN_DATA and IF_TRAN_DATA tables is very transitional, these tables will fill up and be truncated at least once a day if not several times per day.
