Question: I am planning to take data from a mainframe environment to an ODS using a combination of HL7 and a loading tool to ODBC-compliant DB. The end result is that when a transaction is committed at the mainframe, the ODS will receive the resulting data near real-time. This project is taking approximately nine months to complete. Is there a way to calculate best, medium, and worst case time frames for developing an ODS? Are there any metrics associated with this type of project estimation? Also is there a generic project plan for this type of work?
