摘 要  Abstract In this paper, top-down structured system analysis method, described parts of a full-featured computer quotation system development process, operational processes and some of its core technology. This paper carried out the project overview, a brief background of project development, project development and project development objective of the meaning; followed by the system planning stage, the actual business processes through research and analysis of the systems organizational structure, specifically to complete the computer parts quotation system needs analysis, feasibility analysis, the existing business process analysis, and optimization of existing business processes, business processes of the system obtained; followed by system analysis, the specific data flow analysis and complete data dictionary; system completed the design phase the main functional modules of the division, the database design and system interface design. This phase of the function of each module in detail the design, forming a functional block diagram of the system, on this basis, have chosen the right development model; database design first tested the concept design, followed by a logic design, and finally completed the design of the database table. According to the first few stages of the analysis and design, the system used in the design of B / S mode, ASP technology, the basic page design and implementation of function, use Access database backend database. The design and implementation of the system parts for the computer to run a foundation quotation system for computer parts quotation system to provide a good condition.
