Design And Implementation Of CRUD Component Based On J2EE

With the speeding up of economic integration and the rapid development of information technology in recent years,computer applications has gradually penetrated into our daily life,study and work.Because of the good accessibility,generality and extendibility,the B/S based web applications are having a fast development,and they are becoming the mainstream of various application markets.According to characteristics of software development,a lot of work in the process of software development is not complicated,but repetitive.The majority of it is to perform simple CRUD operations to certain tables in the database,and they are just simple copy and paste tasks for the programmers.The developers will not make big modifications to the code,but the workload is very heavy.Although most of the work is repetitive and simple operations,it will produce a lot of bugs.From the above description,we can find that a lot of the work in the software development process is to develop CRUD related functions.The main functions contains add,delete,update and query operations to the database.If such work is developed one by one,too much efforts will be wasted into repetitive work.As a result,in this paper we designed a fast development tools for CRUD combination components.This article presents the design and implementation of the CRUD combination components.It mainly covers the basic components of front end,the interactive interface for the back end and the database,and it introduces the functions and usages of the CRUD combination components.In this paper,we design and implement the system based on the J2EE framework,and we used various techniques including AJAX,XML and JSON.We use Mysql for database,and CVS for version control.By using these techniques,the accessibility and extendibility are greatly improved.Finally,through the function and performance tests,the CRUD combination component is guaranteed to work properly.
