Well it's nice to know with a huge influx of unemployed persons, the English Department for Work and Pensions is ready with a '
new system'.
25+ Million Lines of Code converted using an automated approach
Thus turning the existing documentation into another pile of waste paper. So NO-ONE knows how it all works!
1) The complex database mapping and use of features such as partitioning and Index Organized Tables which resulted in better online and batch performance than on the original mainframe application.
Wow, Index Organized Tables. That's lifting the Dbms into the year... 1991
2) Converting untyped data with COBOL computational items and EBCDIC characters into equivalent ASCII data.
Data conversions often future proof with UTF8/16, but at least the DWP can now operate on an Arduino.
3) Full byte-by-byte reconciliation between the original database and the go forward database ensured any database conversion issues were resolved well before cutover completely de-risking the implementation into live.”
