Preliminary Study Of The Tobacco Industry Erp System Based On J2ee

Informatization is becoming the key factor for the development of enterprises. The capabilities of ERP software directly decide whether or not the informatization construction of enterprises is successful. However, to meet the requirements of varieties and continual development of middle and small sized enterprises, EPR software has to possess the flexible adaptability and convenient expansibility. This paper put forward a pilot study of realization the ERP system base on the J2EE.The pilot study try to provide one resolution of ERP system that the system is open a source code of, face to medium small business enterprise of, be applicable to the trade, chain store, trade of service, small scaled produce business enterprise or construction type business enterprise, be easy to an implement, the cost two-bit. And the system can support the branch sale network,concessionary management network, and can provide for an ASP(Appliance Service Provider).At first, this paper expatiate the background of the ERP system. This part carried on elucidation to development present condition and development foreground of the inland, overseas and the tobacco profession of ERP system. Aim at currently inland and overseas ERP product existent advantage and limitation, put forward the pilot study of realization the ERP system base on the J2EE.This study provide a ERP product for extended in the small business enterprise that the system is the applied cost be low, the systemic deployment be simple, the function cut down be vivid, the yield rate be better, the enterprise risk be low, the business enterprise risk .Later, this paper explain main contents of the pilot study of realization the ERP system base on the J2EE.This paper brief introduced the J2EE technique. The introduction includes the basic concept, system structure and main technique about J2EE.This paper expatiate the design thought and technique of ERP system. Main contents included the system design purpose-provided for the medium small business enterprise; the system technique all says-100% pure Java solution, provide a Java application procedure client and HTML client etc.; the face to customer-medium small business enterprise, the branch sale network, concessionary management network, and the ASP(Appliance Service Provider).)This paper expatiate the structure of the system design of ERP system. The system's structure is a 3-tiers structure. That includes the data service layer, the application service layer and the customer interface layer. The data service layer adoption Oracle, the application service layer adoption Jboss server, the customer interface layer adoption the Java Application combine Web interface. The system deployment in network can be the Intranet deploy, besides which can also carry on Internet deployment. of Intranet deployment applies the Java Application, the client of Internet deployment applies the HTML client.This paper introduced the functions of ERP system. In this part, the paper introduced the function frame of ERP system at first. These function parts include offer-sale order—invoice—receive, requisition to buy—purchase order—invoice—payment, customer relation management, colleague relation management, supply chain management, results analysis, never balanced accounts center, store on the net etc.This paper used two part expatiate two techniques in the ERP system. These techniques are the Application Dictionary and the Work Flow.The Application Dictionary avoided the tedious process that is the applied procedure carrying on a design and coding and testing to each window body of tedious process. In the implement of the process of ERP system, the Application Dictionary make "Write Nothing, Run Anywhere" become reality. Change the sentence talk, the business adviser can have never need to write procedure, can make to order existing business function, or the increment all new business function. In this part, the paper expatiate the design principle, design model, frame, and database model of Application Dictionary.The ERP system provides built-in Work Flow system. The Work Flow is a series of step of instruction, may involve more than one customer. The step can be to start process, circulate statement or input an information in the window way. Examine layer class don't need the Work Flow of show type, but the auto be include into, if at present the words of the restriction shortage of examine of customer. If the mission in the Work Flow because of at present the customer's function or data of safe restriction but can't carry out, circumstance and ex- likeness. The Work Flow can be the mission of the end of month etc. The system provided to prepare definite Work Flow for many not- routine missions. The Work Flow supports a context and it automatically searches the data needed or provides to need recognize tacitly of importation new record a value.In finally, this paper carried on summary. The study of a pilot study of realization the ERP system base on the J2EE obtained some results about system structure, design realization and key technique of the ERP system. But the study still have some shortage. These shortage need to continue to study in aftertime's work and make system continuously perfect and excellent to turn in the excelsior.
