An architecture for supporting batch query and online service in Very Large Database systems

The unprecedented growth of the telecommunications industry and exponential increase in real-time online transactions has created the need for a database (DB) system capable of managing massive amounts of data. However, current very large DB (VLDB) systems can become overwhelmed, and if, for example, a batch query is made while a transaction is being executed, the online service may become limited or system performance may decrease. We propose a partially distributed DB model to address this problem. The model partially separates a batch server, resulting in increased performances in transaction response time and throughput
