Mainly includes the housing stock tax declaration price evaluation system of tax collection and administration mass appraisal technology, B/S architecture and advantages and disadvantages of C/S architecture, J2 EE, Spring Web MVC framework and relevant technology, business management and technical requirements are put forward.3.Analyze the system of business technology needs. First analyzes the design goal of this system and the design principles, and then analyzed the performance requirements of the system, design the system’s overall architecture, briefly illustrates the business queries, audit appraisal, dispute processing, system management to the specific requirements of the four key functional modules, mapped the business flow diagram, use case diagram and data flow diagrams of each layer has carried on the demand and data modeling. For data acquisition, audit appraisal, dispute processing module processes are analyzed in deta il.4.To design the overall structure of the system and the specific function of each business module, the system of seven big function module is divided into: data collection, audit appraisal, dispute processing, business query, statistical analysis, system management, tax calculation.
