Design And Implementation Of Water Conservancy Material Purchasing Management System Based On JavaEE

With the increase of water conservancy infrastructure construction,water conservancy,more and more kinds of material purchasing,material storage,warehousing and inventory processes involved are very complicated,paper management mode,the traditional manual management is not suitable to the needs of modern water conservancy materials procurement,procurement of materials in order to improve the management level of water conservancy,this paper adopts JavaEE technology,Struts technology,JSP technology,JavaBean technology,Tomcat server,MySQL database and the development of the purchasing management system of water conservancy materials.The main work includes the following three aspects:Firstly,system requirements analysis.Investigation and Analysis on water conservancy procurement personnel,personnel management,inventory analysis personnel,and according to the content of the current staff,technical analysis using structured modeling system function demand,including budget management,procurement plan management,procurement management function execution function,report management function,statistical analysis functions,and from the data entry system consistency,response speed,real-time operating system security and other aspects of the performance analysis,to further ensure the operation efficiency of the system.Secondly,system function design.The system from the network topology,server deployment architecture,system level architecture and other aspects of the overall design,and the use of structured process technology to design the system with function,algorithm process of each function is given,using the E-R diagram and table design the database of the system,improve the system of data access,sharing and storage.Firstly,system function implementation and testing.By using the java program in the Eclipse integrated development environment to achieve the function of the system,describes the key operation of each screenshot function of a system,and the system was tested.The test results show that it can meet the needs of police information management,and has better concurrency and throughput.
