Seagate Software Inc will today officially launch its Holos 7 OnLine Analytical Processing application development environment, as the OLAP market readies itself for the introduction of Microsoft Corp’s Plato OLAP server, and Arbor Software Corp’s product suite Essbase applications development (see related story). According to Scotts Valley, California-based Seagate. Holos 7 will enable users to develop flexible and scalable applications that can analyze large quantities of data. Users will be able to combine proprietary OLAP stores into one application. It features, what Seagate is describing as Open OLAP, which joins disparate OLAP data sources so they appear to the user as a single OLAP data source, and combines Plato and Essbase, as well as Seagate’s own Holos offering. Holos 7, which forms part of Seagate’s Enterprise Information Management road map, combines OLAP and relational data sources, a hybrid development environment. Seagate has also added increased communication with SAP customers, who will be able to query the base tables of data help in their systems, and build OLAP cubes directly from the SAP transaction data.
