J2ee Platform To Explore Its Application In The Development Of The Social Security Industry

In software developing,the choice of frame has been a very important factor to the product's success or failure.In the past,the software developing was mainly based on the two-tier frame,because of its advantage of convenience and rapid developing,it has accelerated the process of enterprise's information construction in some degree.But it has some disadvantage of big client and discommodious maintenance and update,this blocked the enterprise's information integrity.The three-tier/multi-tier frame promotes the flexibility and performance of software,so it has been the popular frame in software developing at present. At present,.NET platform and J2EE platform are all popular three-tier/multi-tier frames,they all give some guidance and criterion in design,integrity,performance, security of multi-tier appliance.J2EE platform gains more applications by its migratory,open,security and performance advantage. This issue gives introduce and compare to the software developing frames,by studying J2EE platform deeply,it shows the advantages of J2EE platform.It gives the theory foundation of J2EE platform,including technologies and design patterns.Based on the J2EE theory and labour and employment requirement,I designed and developed the Labour and Employment Management Information System(LMIS). This issue introduces the requirement,goal, characteristics of LMIS,and makes J2EE platform as the system frame.Then,it introduces the LMIS's system frame, including data encapsulation,all tiers design and realization,exception and log design,etc. By explaining the analysis and design of the profession training module of LMIS ,it shows the appliance of the system frame in system developing. It gives a pattern in software developing.At last,by summarizing the LMIS system,it gives some advice to the software developing.
