(This course is a course of building a paas platform. Paas is the second layer of the three layer concept of cloud computing. It proposes a platform and services to provide customers with a development platform. Even if customers do not clean up any programming knowledge, they can also customize software modules according to their own needs. In the course, the concepts of office flow middleware and metadata are introduced. The powerful office flow middleware ensures the stable operation of the system process. The customized office flow middleware can also be adjusted according to the needs of the paas platform. In the course, the functions of the organization of the office flow reverse synchronization platform are explained. The office flow provides RMI services, and then implements distributed deployment, strengthening the system functions. Metadata is derived from the first-line meta model in the mathematical model, which protects data with more detailed data granularity. In addition, two metadata management methods are provided in the course, namely centralized and open metadata model management. This document includes the following annexes:
