RE: what is the difference between ODS and OLTP
 
ODS is an Operational Data System, which contains the snapshot of currently loaded data for clerical day to day analysis and includes a little history, 30-60 days of historical data in addition to the current data.

OLTP is Online Transaction Processing System, which contains only the current data and keeps changing, not suitable for analysis due to temporal inconsistency unlike ODS which contains consistent data.
