My first idea was to throw away table BALANCE and work without it.
I even created a PL/SQL function for real-time calculation of article
balances.
But after some time of thinking I realized that this design will constantly
slow down, year after year - it will have to work with more and more records.
So I rewrote my script for data transfer, using INSERTs with multiple VALUES
and now running time suddenly shortened - it is now 496 seconds for about
837 000 records.
But it is still interesting for me why running time was increasing with each run (it may be still increasing even with
thenew script).
