Building the Operational Data Store by William H. Inmon

Other chapters address standards, reengineering, data builing, and the role of star schemas in the ODS. The hardware and software requirements chapter addresses a number of interesting technologies that may be applicable to the ODS.

There are lots of big ideas in the book, and what you find may surprise you. They are the “pure” DSS processors. 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.

Both of these tendencies enrich the topic that he is addressing, in this case, the Operational Data Store. Paperbackpages. But there is a fly in the ointment of this approach. In addition, the fact table is familiar to the end user, in terms of the day-to- day structuring of data that the end user is accustomed to seeing.

Farmers usually find small flakes of gold, not huge nuggets, at the completion of their transaction. No eBook available Amazon.

The second chapter elaborates on another big Inmon idea—the Corporate Information Factory. Its underlying technology is complex. The Operational Data Store: DM Review Extended Edition. The ODS requires changing or replacing old legacy systems that are unintegrated. The fact table represents the structure that holds the majority of the occurrences of the data. Explorers look for associations between types of data, patterns that are useful and relationships that have heretofore never been discovered.

Marco Garcia marked it as to-read Mar 05, Steve Hager marked it as to-read Jan 01, Scott marked it as to-read Mar 12, The ODS is a hybrid beast—partly in the world of operational systems and partly in the world of decision support. This book is not yet featured on Listopia. The ODS is integrated, subject oriented and supports some important kinds of decision support. This book is the definitive source for the subject of multidimensional database design.

Building the Operational Data Store, 2nd Ed

Both approaches have their strengths and weaknesses. This argument is quite strange because the ODS is one of the most pervasive architectural structures found in information systems today. Xtore concentrates on the technical aspects, while the other concentrates on the people aspects. The ODS must satisfy the needs of both the farmer and the explorer; and because of this paradox, the design of the ODS is a difficult task in the best of circumstances.


Some key reasons for building an ODS are to integrate operatlonal data, to use for decision support, and to stage data for analytical processing. For those parts of the system used primarily by farmers, a star join approach is optimal. Explorers, however, seldom do on-line update.

Farmers know what they want when they set out to search for something. Scott Wood rated it it was amazing Sep 19, With the help operahional fascinating and instructive case studies, Inmon shares what he knows about: Bruce L marked it as to-read Oct 28, The book is a mix of theory, practice, and methodology.

He is intrigued by the enterprise, enterprise architectures, and data warehousing. John rated it really liked it Oct 26, There are several well-known packages that implement an operational data store.

A later chapter discuss four types of operational data stores, which are primarily distinguished by the speed at which data is read from operational systems and loaded into the ODS. Javiera Rojas marked it as to-read Feb 12, But if update processing is being done by farmers or if there is usage of the ODS by explorers to any extent, then one or the other form of normalization is in order.

He is known globally for his seminars on developing data warehouses and has been a keynote speaker for many major computing associations.

The designer in the ODS environment faces Hobson’s choice. Books by William H.
