Design of Mimic Database Middleware Based on NETTY

Most information systems involve database access operations, and security reinforcement using a mimic architecture is an important way to achieve the endogenous security of information systems. However, how multiple executors in the mimic architecture access the database is a thorny problem. If each executor is equipped with a database one by one, it will not only increase the cost, but also make data consistency maintenance of each database more complex. The mimic database middleware based on NETTY adopts the general idea of "many to one request; one to many replies". First, the database access requests of multiple executors are adjudicated, merged into one request and sent to the database, and then one response of the database is returned to multiple executors, which better solves the above problems. The bottom layer of the middleware adopts Java, which has the cross platform characteristics of Java; The security of data access is enhanced by multi executor request adjudication; The test results using the middlewareshow that the performance loss is about 20%. The mimic database middleware makes the mimic system unnecessary to add databases, and provides an optional extension tool for the mimic information system.
