The Design And Implementation Of Land Appraisal System

The thesis introduces the analysis, design and implementation of a Land Appraisal software system based on C/S model, and expounds its technical points and difficulties.The system is the established on computation model in which excel is taken originally as main calculating tool of the real estate project's appraisal-surveys. The system establishes the appraisal mathematical model according to "The Economic Evaluation Method of Real Estate Development Project", it can survey Real Estate development project's purchase cost, income, and can carry on the project feasible finance analysis. Also, client/server model theory is utilized in the actual software development design, to realize the data's centralized management, data real-time sharing. According to SQL Server-relational database management system's superiority, it realized data integrity and security.Firstly, the thesis introduces relevant theory and background knowledge. Then it advances the entire design goal by making analysis of the project's demand. After deep analysis of the demand the article puts forward the modular function division of the system, and designs the system in detail in the light of the principle of MVC development framework: from UI layer to inter-logic layer to database layer. Next, the article describes the Algorithm used in the key module. Finally, the article makes a summary of some imperfect parts existing and presents the writer's own idea on the improvement of the system.The article's main characteristic is establishing following kinds of appraisal-models and realizing them on programming according to "The Economic Evaluation Method of Real Estate Development Project":①,Dynamic retrieve cash flow table model, calculating FIRR, FNPV, Pt.②,Analysis of uncertainty model, Analyzing the influence of FIRR or FNPV caused by selling price, development cycle, building cost, volume rate, land-obtaining expense.③,Critical point analysis model, calculating the highest land-obtaining expense.Therefore, the system provides a set of science, effective appraisal-model for real estate development project investors, also makes real estate project management easier and more efficient. So we can make reasonable arrangement for more efficient economic goal. Furthermore, the author believes the discussion about the development of Software, must be helpful to those developers who are exploring in this field.
