Design And Implementation Of Government Investment Attraction Service Platform

At present, the investment is still the main driving force of China’s economy. The investment attraction work has been a focus of local governments. With the development of information technology, the investment attraction department has also started the construction of information technology in order to assist the management of investment attraction and improve the efficiency of investment attraction.The work of this thesis is to design and implement a government investment attraction service platform system, and the thesis describes the process of the technology research, requirement analysis, system design and system implementation of the platform.The technology research includes C/S architecture, B/S architecture and ASP.NET. The aim of C/S architecture research is to understand its composition structure, the relationship between the various parts and the way of realization. The aim of B/S architecture research is to grasp the principle of B/S architecture and its comparison with C/S architecture. The aim of ASP.NET research is to use it to develop the system. In the research of ASP.NET, this thesis describes the position of ASP.NET in the.NET platform, and the development mode of ASP.NET.In the functional requirements analysis, we first classify the users, and define the roles of the users in the system. And then, according to these roles, the requirements of the functions are described. In performance requirements analysis, the requirements for security, reliability, ease of use and maintainability are described.In the system design, the design criteria of the system is set up firstly, and the design of the system is described from several aspects, including architecture design, modules division, functions design and database design. Architecture design shows the system’s hierarchical structure from a macro perspective, describes the function of each tier and the connection between the tiers. Modules division groups the functions which are closely related each other according to cohesion degree, in order to facilitate the development. Function design describes the input and output information of each function and processing process. Database design describes the system business logic data’s structure and definition.The realization of the system includes the creation of the software project, the realization of the data access tier, the realization of the business logic tier and the realization of the function. In the creation of the software project, the project’s creation process in the integrated development environment and the final code structure are described. In the realization of data access layer, the generation methods of entity class and data access class are described. In the realization of the business logic layer, the division of the namespace and the business classes’ definition are described. In the realization of the function, the realization mode of functions is described, and the GUIs of functions are displayed.
