Based On The C / S, B / S Mixed-mode Injection Mold Quotation System

The rapid development of computer, network and communication technology brings new revolution to enterprise. For example, in the field of market competition in 21 century there are many new points: Product life cycle is shorter, product variety become more and more, in opposition client's demands in goods and services are much higher. So how to get enterprise in a position that at the beginning of quotation, give the client a rational and satisfying bid, therefor at the same time not sacrifice oneself is very important. Inquiry and quoted is clients and enterprises' initial osculatory, and also plays an important role to obtain latency client, get client order, detain old client. If enterprises ignore them ,they will lost old clients, orders, even make clients turn to the competitors, so Inquiry and quoted supervision and decision are of consequence in business management.To mould rate in China, There is not an authoritative and applicable calculation of mould price. Because of the large impact of human factor, the price of mould is very confusable. Through the study to correlation enterprises,the analysis on quotation's status quo, available intranet environment, long-term mode, developing trend of operation and management in mould enterprises and along with computers' predominance, this paper put forward "modified working hour calculation method of mould price". In order to get data and variety more, database management agiler, security requirement higher, basing on C/S,B/S pattern merits and disadvantages,the development of this software adopts C/S and B/S mixed pattern separately. C/S pattern deals with high processing frequency, large transmission of data, high security requirement and B/S pattern with wide scope business,low security requirement. In this way, C/S and B/S mixed mode makes use of C/S and B/S' merits, fulfils different demands in mould quotation business, at the same time, urges smooth transition of the enterprise inherent management and offers corking expansibility to new demand.First the paper analyses the concurrent quoted theory inland and overseas, the actuality of quotation business, the component of mould price, incorporates mould offer operation and point ,compares currently popular offer's theories and methods, selects working hour calculation method of mould price as theoretic base and modify it with computers predominance, then analyses the advantages and disadvantages of C/S and B/S pattern and demonstrates the feasibilities and superiorities of mixed pattern.In the third and fourth chapter, the paper reasons the system structure of C/S andB/S, the key techniques, the tools of software development and the selection of DBMS. The paper expounds the design and implement based on the mixed pattern of C/S and B/S. It consists of demanding analysis, system structure, data flowing diagram, function module and the application of key techniques, takes and organizes offer parameter and data, uses entity-relation(E-R)pattern to design data pattern, selects MS SQL Server 7 as database, founds database physical structure. It gives a detailed expounding about database's dynamic links, gives out a security mechanism combined by two kinds of security scheme. It uses Delphi programming language to complete two subsystems: C/S and B/S. C/S subsystem mostly includes user management, data management, offer management, log sup management four modules. B/S uses activeX technology to realize quotation on net. At last, it specifies by an actual engineering reckon example that proves the software system' veracity and practicability.In the last part, the paper sums up the key points and gives an expectation of developing direction of mould quotation system.
