Design and implementation of ks004 based on SSH address book system

This system is based on SSH Framework to implement , Database adoption MYSQL, Development tools are eclipse or IDEA, The front end uses JSP and jquery-easyui To implement , Simple and generous , The operation is correct . Suitable for course design or homework .

2  System requirements analysis

  Purpose ： The purpose of the feasibility study is to determine whether the problem can be solved in as little time as possible at the least cost . The system officially uses a relatively simple Java Language to write a small 、 Practical address book information management system , It can not only complete the management of user information , And more economical . This system uses Java Language , In terms of technical difficulty , Due to the guidance of the instructor and relevant references , In particular, there are abundant relevant materials on the Internet , By referring to the design of some functional module programs , It is completely possible to realize the system .

  The design of this system is in windows XP In the Chinese version , Use eclipse+mysql Developed . It can run on windows XP Database development system of relevant platforms .SQLyog It can not only simplify database management , And the application development process is more reasonable , It enables the organization of data , Defining database rules and building applications becomes easy , Using visual design tools and wizards , Users can quickly create forms 、 Query etc. .

2.1   Requirements overview

This system mainly realizes the management of address book information , Main functions :

（1） System login

（2） Address book management information : Addition of information 、 Delete 、 Browse 、 Modify and query operations .

（3） Data paging function , front end easyUI frame

2.2  Functional analysis

Address book add , modify , Delete , Query and so on .

2.2.1   Front desk function module

（1） Sign in ： Dynamic login mode , It's refreshing .

2.2.2   Background function module

（1） Inquire about ： Query all data .

（2） modify ： Modify the data selected by the user .

（3） Delete ： Delete the data selected by the user .

（4） add to ： Add new address book data .

3  The system design
