Oracle did manage to make some announcements at its Open World event this week without mentioning the network computer. One was the launch of tools to build data marts and data warehouses.
The tools consist of a Rolap (relational online analytical processing) option for attaching to the Oracle database, and an upgraded version of the Discoverer analytical software.
The Rolap Option provides a calculation engine for compute-intensive analysis, such as sales forecasting, that works with data held in a relational, rather than a specialised Olap query database. This simplifies database administration. The Option is based on Oracle Express Server 6.0 and is Web-enabled. It can be used for complex 'what-if' queries. Some or all of the data can be cached in a multidimensional cache to improve response times.
Discoverer 3.0 is a query and reporting tool that can be used in conjunction with its other analysis tools, Express Analyser, Sales Analyser and Financial Analyser. New features include summary management, which automatically redirects queries to summary tables, based on frequently asked queries, that speed up access. A predictive query governor tells users in advance how long a query wil take, rather than just aborting queries within a specified timeframe.
Pricing has not been decided but the Rolap Option will ship in January and Discoverer 3.0 in the first quarter of 1997.
