The paper discusses MOMAT (Message Orientated Modeling and Analysis Tools) which is designed and implemented as middleware for performance of message oriented modeling and analysis tools for naval combat system (NCS). NCS consists of various large-scale components such as communication service and data distributed service (DDS). Furthermore, MOMAT meets requirements of NCS to support several versions of control such as components, interfaces, messages and publisher/subscriber paradigms. The MOMAT dealing with real-time data changes using continuous query (CQ) to provide new result from the database without issue same query repeatedly. However, a large number of continuous queries may be executed simultaneously over a high throughput of incoming data that may deteriorate system performance and cause data (message) delay. Therefore paper proposes a query split mechanism for performance improvement of retrieval in middleware systems. The implementation result shows that our proposed query-split management scheme significantly reduce workload of database server and increase scalability of each application.
