Simon Griffiths rated it liked it Jun 14, Managing the Operational Data Store Environment. Since farmers have a predictable and repetitive usage pattern, a star join can be created to allow them optimal access.

As further evidence of the health of the ODS, in a recent private conference, seven information systems directors of large, well-known companies spent time describing their environment. Trivia About Building the Oper Conclusions Bill Inmon generates a lot of ideas in his writings, and there are two fundamental tendencies that characterize his work. Arka Bhattacharya marked it as to-read Feb 02, opegational If explorers do update at all, it is by creating sweeping batch programs that march across entire tables and make massive changes.
Scott marked it as to-read Mar 12, The designer in the ODS environment faces Hobson’s choice. The fact table represents the structure that holds the majority of the occurrences of the data. Figure 1 shows the classical positioning of the ODS.
He is Chief Technology Officer at Pine Cone Systems, a company that builds software for the management of the data warehouse environment. Some skeptics question the existence of the ODS. He addresses his topic in an architectural framework—something that few other authors do.

Bart Du Bois added it Feb 05, 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.

Integrating the ODS with data marts. 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. This includes personalizing content, using analytics and improving site operations.
There is a very dual role played by the ODS.
Its underlying technology is complex. In order to understand the foundation of the design of the ODS, you first need to understand that two very different types of users are attracted to the ODS–farmers and explorers.
In order to know how to create the star join, the designer must make assumptions about the usage of the data. When the volume and usage of the data are factored into the design, a mutant form of normalization is achieved.
In a DSS world where there is no update, opedational is not a problem. The essence of an ODS is the enablement of integrated, collective on-line processing. The many normalized tables are combined into a form of srore design that can be described as lightly normalized design.
Figure 2 shows the steps leading to a DSS design. But in an ODS world srore on-line update is a normal event, the inability of the star join to gracefully handle updates presents a special challenge. Open Preview See a Problem?
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.
