Abstract:

By analyzing the existing problems of traditional OLAP systematic in a web environment, a system structure of OLAP system based on object pool and data caching is proposed. The definition of data pool is given, and a processing user request algorithm is proposed. The definition of data cache and data cache processing algorithm are given. Object pool holds certain quantity of objects. An object is a function unit capable of providing decision support, which visits data in the data cache. If the data does not exist, it turns to the OLAP server so that the system performance can be greatly enhanced, and the OLAP server’s burden is lessened. Finally, system implementation and application results are discussed.

Key words: online analytical processing(OLAP), Web, object pool, data cache
