What needs does it satisfy? An ODS provides a foundation for collective, up-to- the-second views of the enterprise. This chapter opedational recommends staffing levels for development an maintenance of the ODS.

But there is a fly in the ointment of this approach. Figure 1 shows the classical positioning of the ODS. Its underlying technology is complex.
The heart of the book addresses how to build an operational data store. He is known globally for his seminars on developing data warehouses and has been a keynote speaker for many major computing associations.

The notion that the ODS is not a legitimate structure is news to SAP, Oracle Financials and PeopleSoft–three of the most widely implemented pieces of software in the s which happen to contain major components which are decidedly ODSs.
There is a second problem with star join structures, and that problem is that on-line update plays havoc with the underlying data management required to make the star join complete.
