Design And Development Of Aerospace Enterprises Business Management System Based On MVVM Middleware

With the rapid development of aerospace industry,the management of internal personnel and comprehensive business in aerospace enterprises is becoming more and more complex,and its demand for information management system is also growing.An existing system of aerospace enterprise in Shanghai,as an example,has been unable to meet the needs of the management of comprehensive business which is multiple levels classified and across different departments.As a result,the enterprise development is restricted.In order to improve the management efficiency of the enterprise,the paper builds a comprehensive business management system of Shanghai Aerospace Electronics Research Institute as the main target.The main contents of the work are as follows:First of all,this paper does a lot of related researches about aerospace business informatization construction to deeply understand its core business.Then it makes a detailed analysis and system design with the requirements of Shanghai aerospace enterprise.Secondly,to solve the problems such as low efficiency development on front end and hard to maintain the codes during the development of business process management(BPM),this paper designs and implements a middleware based on MVVM pattern.The middleware is specially designed for BPM system development.It loads BPM functions with directives to improve the developing efficiency,the scalability and maintainability on front end of the system.Atlast,using the above middleware and AWS BPM development platform,it builds the system framework containing the database,data interfaces,the page routes and business process pages to implement the BPM system of aerospace enterprise.The system is currently deployed to an aerospace enterprise of Shanghai.It works well and is used for more than one thousand people.It not only simplifies the process of business,also contributes to the development of national aerospace informatization.The middleware based onMVVM in the paper provides a new method to develop front end of BPM systems,instead of redundant and hard maintenance codes.
