PaaS-based heterogeneous software integration method and system

The invention relates to a PaaS-based heterogeneous software integration method and system. The metadata capability of the PaaS platform, the capability of a process engine, the configurable capability and the user-defined function capability are utilized to carry out data and logic state packaging and data format conversion on data access interfaces of two IT software systems, and abstraction iscarried out on the synchronization processing logic, and finally, a set of graphical user interface is provided for the user; set of service data synchronization logic rules can be generated by a userin an interface configuration mode, then translation, interpretation and execution are carried out by a rule engine, and finally, service data connection between two IT systems can be quickly realized. The PaaS-based heterogeneous software integration system has the advantages of being good in universality, convenient to operate, low in cost and high in development efficiency. 本发明涉及一种基于PaaS的异构软件集成方法和系统，利用PaaS平台的元数据的能力，流程引
