Research And Application On Multi-Tiered Framework Technology

With the increasing complexity of software systems, the architecturedesign becomes more and more important. Because the mainstream of thepresent enterprise level application is the development of the framework and theCOM development. The better multilayered system construction makes theenterprise finishes the complicated system development and application.This paper studies the technology support service system of the OracleEBS which is based on the J2EE. It is a service system which is aimed at OracleEBS (Oracle E-Business Suite) which is a large management software. Theusage of this system can solve various complicated problems quickly whichoccurs in the employment and using process of Oracle EBS. In doing so, theservice management can be standardized, assembled, modeled. And the level ofmanagement can be improved greatly.In this article studied the technology support service system of the OracleEBS's high complex, it may provide the intermediate level integration overheadconstruction, uses for satisfied the high usability, the redundant reliability aswell as the extended application request. Then, use the J2EE platform, adoptingthe business in the software expression level, the logic level and the data lastinglevel newest module technology design the plan of this system softwarestructure: Struts+Spirng+Hibernate multi-tiered system construction in whichthe presentation layer is achieved by the use of struts, business layer is achievedby the use of spring and data persistence layer is achieved by the use ofHibernate. This plan resolves many a problems very well, such as how to buildthe user interface, where business logic resides in and how to achieve datapersistence. The framework makes that technology of every level needed to achieve has a suitable set at the three-tier structure of the system, and thatdesign is not only loosely coupled but also easy to change。Moreover, the service technological process and the business logic ofOracle EBS are analyzed. A set of the business model are constructed. Thismodel squared with the norm of the service, which can meet the needs of thequality improvement, the service standard and the service molded. The reuse ofthe similar system can be obtained. It can be very useful.In a word, this paper designs the software structure aiming at thetechnology support service system of the Oracle EBS. The typical module ofthis system is built. It uses the multi-tiered system construction to build thewhole system structure. On the basis of the structure the business logicalmodule are realized, and then the system is achieved. The practice proves thatthis article through design at the technology support service system of theOracle EBS completed on the multi-tiered system constructionstruts+Spirng+Hibernate to satisfy with the contact surface request nimble andmaintenances good, but also may separate the data accessing and the dataperformance, moreover is strong through an expandability, is advantageous forthe expansion controller, maintains the entire process, thus effectively reducedthe complexity and reduce the cycle of the development. At the end, this servicesystem has achieved the good application effect.
