Design And Implementation Of Real Estate ERP Information Management System

In this thesis, the Railway Bureau real estate enterprise information construction as the background for the development of enterprise ERP system tailored for the target, around the China Railway Bureau Real Estate ERP information system construction, in turn introduces a systematic study on the back, the development of purpose and meaning. Before carrying out the specific development, this thesis first present a typical real estate ERP system, the author draws this in the development of these systems, and then analyzes the system Web development technologies. Project development process follows the software engineering implementation, during the system requirements analysis use case diagrams and use case specification are used; subsequently class diagrams and sequence diagram are used to describe the system design and implementation; during project development and the system network deployment, functional tests are used. End of the article gives a summary of this development and the advantages of the system and the next phase of work.The system functions more comprehensive to meet the needs of China Railway Bureau daily business management, system function modules include system registry, business management, human resources management, coordination between the various branches of the company management, knowledge management. The system involves more functional, the author describes in detail the requirements analysis phase functional and performance requirements of each module of the system, followed by focused, part of the core functions of the system of financial management module to patients, introduced the system design, implementation and testing process, and thus demonstrate the software development process. Financial management module is divided into data entry module, sales management module, report management module and file management module, in addition to the text design and implementation of these modules is described in detail, but also gives the overall system implementation interface.System development using object-oriented technology, system requirements analysis and design process, widely used UML modeling tools to improve the efficiency of the system as well as the preparation of documentation system development efficiency. Testing phase of the system of integrated testing tool LoadRunner complete the system performance test, and in the test on the basis of the detailed function of the system to complete the test.This system will be useful in the design process technology and advanced software design methods of effective integration. Using a combination of Java EE technologies, workflow technology, C/S and B/S hybrid structure model, and fully guarantee the system’s utility and simplicity of operation. Meanwhile, the system development fully consider the security requirements of the system, using a variety of security technologies, including role-based access control, encryption of data transmission, secure transmission protocols, data redundancy and other measures.
