Building Material Witness To Send Samples And Testing Management System Design And Implementation

In recent years, with the development of network technology, the traditional bidding'sShortcoming has become more and more obvious。the materials involved in the witness and test of the building materials sample become more and more,the data produced in the process of data management become more and more complex.this make cheating in that process become more and more frequent. Therefore,development of of network-based building materials sample witness and test management system has great practical significance and value. building materials sample witness and test management system using the means of network and information transfer traditional biddding to online form,it can link various roles in this system. building materials sample witness and test management system makes full use of the Internet's operating costs low, scope, advantages to make the traditional open-bidding activities osimple and fast.After the analysis of research projects in the background, status ,system choose to using B/S structure for the system archtecture based on the analysis of traditional wintess and test process and characteritics,system select the popular system development portfolio j2EE For C/S system for the development language, Specific work of this paper is as follows:1. get the system demand analysis before the design and inplementation of the system,after cosidering the kinds of users when we move building materials sample witness and test management system to online ,we get users involved in this system.then we get case analysis of every user。after all of that we get performance requirements analysis of the system from the response speed, error handling and exception recovery respect2. after demand anslysis,we begin to design system function modules,before design the modules of the system,according to the process of building materials sample witness and test we devide the system into three susystem: building materials sample witness management module,building materials sample test module and system management mdule.then we analysis every subsystem from system process,system use case and system order.after we complish function module analysis we begin to design the database.system database design mainly complete system3.implementation of the system。we inplement some important module and interface. Including:system login interface,base information management interface,sample witness recording interface,sample receive recording interface,sample testing report interface,evaluation and search management module4. system testing is the most important part after the completion of system,we have done system test environment,system test design and system test process analysis.after this tasks,we get the test results.
