Research on Application of Distribute OLAP System with an Improved Election Algorithm

摘要：

The OLAP system can support enterprise decision well through intelligent query with data of enterprise.To deal with abundant and complicated query tasks OLAP system needs high performance server,so that the cost of OLAP system is higher for most middle and small enterprises.With the aid of distribution technology,we can deploy OLAP system on multiple minicomputers according to allocating tasks to each server,so we can attain application of OLAP with existing resource of enterprise.The system coordinator is selected by using election algorithm.In a full-connected LAN,the adopted election schemas are generally the classic Bully algorithm by Garcia-Molina or improved ones.In this study,we propose an improved election algorithm suitable to the distributed OLAP system.Using the new algorithm can improve the system performance and produce fewer messages.
