Research And Implementation Of Entity EngineBased On EMA Platform

With the development of software developing method and the increasing of the software platform level, a new method of the software development rises--- EMA method. Based on the method, our team begins to study and create an EMA platform. We start our work with finding the main elements of software. The author gets the EMA method's core ideas by analyzing these elements' relations. Because the EMA flatform need define the Meta data, it needs a layer: persistence layer. Firstly, the paper introduces the whole designment of the EMA Platform. Secondly, the paper introduces the designment of the persistence layer: Entity Engine. The goal of the entity engine is to simplify the enterprise wide use of entity data. This includes definition, maintenance, quality assurance, and development of entity related functionality. With no entity specific code entities can be created, stored, removed, found, sorted, cached, etc through the single Api of Entity Engine.
