Technical topics include monitoring system utilization, monitoring the growth of the user base, the daily and nightly workload, ways to distribute the workload, capacity planning and service level agreements.
He is intrigued by the enterprise, enterprise architectures, and o;erational warehousing. The explorer operates in a random manner. 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.
The Operational Data Store: Designing the Operational Data Store – DMReview
Mike added it Feb 09, As datq hybrid, its design must necessarily be constrained by conflicting requirements. The most comprehensive guide to building, using, and managing the operational data store. An ODS is an integrated, subject- oriented, volatile including update ghe, current-valued structure designed to serve operational users as they do high performance integrated processing. An ODS supports on-line update. Explorers operate in a pattern that defies prediction.
Business process reengineering and the ODS.
Farmers know what they want when they set out to search for something. Alan Stickler marked it as to-read Aug 06, Thus, the ODS designer has a dilemma. An ODS delivers consistent high transaction performance–two to three seconds. No eBook available Amazon.
Building the Operational Data Store
Methodology The heart of the book addresses how to build an operational data store. There are two essential parts to a star join– fact tables and dimension tables. The many normalized tables are combined into a form of physical design that can be described as lightly normalized design.
Dimension tables contain data which is not terribly voluminous. Operatoonal operate in a heuristic mode. Javiera Rojas marked it as to-read Feb 12, Database and Data Warehouses.

Daniel Bos added it May 08, Builidng 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. The ODS must satisfy the needs of both the farmer and the explorer; and because of this paradox, the design of the Injon is a difficult task in the best of circumstances. The other type of table that participates in a star join is the dimension table.
Justin added it May 21, If you like books and love to build cool products, we may be bui,ding for you. This book will show where it fits in the corporate information factory as well as how to design it, build it, and manage it.
It generally serves some operational needs as well as some decision support needs.
For those parts of the system used primarily by farmers, a star join approach is optimal. So it is peculiar that industry experts are questioning the validity of the ODS.

The people-oriented chapter concentrates on the skills necessary to implement and manage the ODS, including requirements gathering, design, project management, development, testing, and system integration. The ODS was a prominent feature of each of these companies’ information systems architecture.
This chapter outlines the main constructs in the Corporate Information Factory and shows how the ODS fits into the overall environment. Because of the many roles that an ODS fulfills, it is a complex structure. Wiley Computer Publishing Timely.
