Development And Maintenance Of WEB Application Lysithea Based On Barista

With the rapid development of network technology and the widely use of J2EE platform, many enterprises build enterprise-scale information applications based on Internet.The project is derived from the Lysithea system which I enrolled in during my internship in a software company. Lysithea system is an Enterprise Application System based on J2EE Platform. It is mainly used for the collection and management of the workers'working time. Our aim is to design a system which can be custom-built based on the matrix expediently, neatly and rapidly. The contents customized include design of the new functions and changing of the old functions, i.e. design and maintenance. Because of this advantage, the system now has more than 100 customs gradually in which there are large corporations of auto car and gasoline and even department of public traffic.This paper focuses on customize of the system through some new functions being built and some original functions being changed. Firstly, under the background of the requirement analysis of the whole system, this paper gives the detailed and allround requirement analysis of the maintend function. Then on the base of deeply analysising of the web application framework named Barista, this paper completes the work of function design and detail design and at last realizes the maintenance.
