Currently, the increasing popularity of network - based computer applications , with the approval for land use and continue to deepen reform , land and operating approval makes it possible to further standardize land approval to implement online . Land development approval for all examination and approval system , whose main task has two aspects : first between the various departments , information sharing exchange of land , the second exchange of information , sharing of information, the terms of the collaborative work environment based the online joint approval for land use and business processes to achieve in order to form a virtual community , the services provided by the land development approval . This our online land approval of construction is still in the beginning to realize that the technology is not perfect , system scalability , usability , maintainability poor . This paper is to construct a reasonable land resources online approval system , and the analysis, design and implementation . The program is based on the the java web of multi-level distributed architecture , using the model design and develop new ways to rely on the organization of the modules of the software between . (1) Java Web - based multi-layer distributed architecture design . In this document , the application of e-government approval system , multi-tier distributed architecture Java network research , analyze its advantages ; (2 ) research and application of design patterns . In this paper, the design mode , its elements , advantages , classification analysis of the theory , as well as common principles ; (3) software design based on component technology . In this paper, a component-based software design thought, some features of the system is achieved through the use of third-party components , to save development costs and improve development efficiency , improve the reusability of the system ; (4) approval system design . E-government approval system needs analysis , the overall design . On some of the key issues in the realization of the system , such as the approval workflow , user rights , database connection , a detailed study ; (5) the examination and approval system design and implementation . In this paper, the e-government approval system building programs Handan County administrative examination and approval system , the system functions . ( 6 ) Finally , design and implementation of the system are summarized and proposed land development and improved online services platform conceived and recommended approval system .
