MYSQL Distributed Database Middleware

With the rapid development of Mobile Internet, operator subscribers have been shot up, and it has resulted in a geometric increase in its consequent data. According to the research released by Deloitte & Touche, in 2012 the existing data of operator customers hit 19.2 billion, and the total data capacity reached over 21 TB. The core system such as the accounting system of the online transaction support and CRM (Customer Relationship Management), will be especially under a huge pressure on performance and extensibility. The traditional Centralized database has been unable to meet the demand of business growth due to its high price and extensibility problem. Moreover, with the high-performance and high-extensibility cloud computing system points at non-supporting analyzing application, but it won’t support the online transaction as the traditional DBMS.In accordance with the XXXX company requirement that the data is service, this thesis raise an integrated method to create a DAAS platform combined with the Distributed Data middleware, the MYSQL Database and PC Service, which is based on the latest technology of cloud computing system. The system has the following four basic characteristics:1st, the uniform provider and the transparency of application of database; 2nd, the high availability and the ability to record the "single point of failure" of data; 3rd, the dynamic adding and eliminating nodes.4th, the isolation which means it could isolate the data source. BY the measurement of the TPC-C Test, the Distributed Data middleware is quiet adequate to support the standard MYSQL OnLine Transaction Processing. In addition, Distributed Data middle-tier will not only ensure the funcition but will also make a certain the system scalability.
