A scalable generic transaction model scenario for distributed NoSQL databases

With the development of cloud computing and internet; e-Commerce, e-Business and corporate world revenue are increasing with high rate. These areas not only require scalable and consistent databases but also require inter database transaction support. In this paper, we present, a scalable three-tier architecture along with a distributed middle-ware protocol to support atomic transactions across heterogeneous NoSQL databases. Our methodology does not compromise on any assumption on the accuracy of failure modalities. Hence, it is suitable for a class of heterogeneous distributed systems. To achieve such a target, our architectural model exploits an innovative methodology to achieve distributed atomic transactions. We simulate this architectural setup with different latency tests under different environments to produce reliable impact and correctness.
