Open-Gate: An Efficient Middleware System for Heterogeneous Distributed Databases

Free registration required

Executive Summary

Middleware has become an essential component for almost every distributed database system. It uses wrappers when integration is achieved for heterogeneity. Different middleware systems have been produced aiming for a better performance. In this paper a new middleware system for Heterogeneous Distributed DataBases (HDDBs) called Open-Gate is proposed. Its main objective is to provide an efficient system with the characteristics of autonomy, scalability, reliability, and high performance. In addition, it can handle a huge number of users overcoming the bottleneck problem or loss of user's queries. Experimental results show that, the proposed system achieved high performance compared to other systems.
