Key Issues Research On ERP System Based On SaaS And SOA

Now the enterprise management is realized by the ERP system, which has a several characteristics including an amount of data, a large number of users, the complexity of business logic, the complex and various business process etc. So the ERP system to be developed needs in steady, opened, extendable architecture. At the sametime, medium and samll enterprises are limited by financial resources, inadequate investment in management technology, and lack of IT technical staff, which results in the traditional model of software sales as product in excess of the capacity of medium and small enterprises. In response to these limitations, this paper posted developing ERP system based on the SaaS pattern and SOA architecture, which supported to design multi-Tenant, high performance, easy to expand solution scheme of ERP system, in order to helpe medium and small enterprises realize the " that is used. and that is on-demand " information by low-cost, low jumping-offpoint.Firstly, by introducing the related theories of the SaaS pattern, SOA architecture and the ERP system about the basic concept, the relevant characteristics and the current state of development, this paper posted the theme, the ERP system research based on SaaS pattern and SOA architecture, and expressed the necessity and significance about its research and development. Based on characteristic of SaaS pattern and SOA architecture, research configurability under muti-tenant application page element; then propose solution schema about it; propose a muti-tenant data extension schema based on XML, in response to localizations of share data model of muti-tenant extension at present; research the data security under SaaS pattern, propose user data security strategy based on CP-ABE algorithm; In the SaaS application based on SOA, research configurability under muti-tenant business process, then propose solution schema about it. And then, after analyzing the J2EE platform architecture and MVC pattern, this paper constructed the application framework based on integrating the Struts2, Spring and Hibernate framework. The application framework inherited the advantage of J2EE platform and MVC pattern, including the normative framework, the clear system layers, supporting across platform implements, excellent compatibility etc. realized SOA architecture by Web Services technology, in order to loosely coupled between subsystems within the system. Thereafter, based on the application framework, the paper analyzed the ERP system functions, and took device management system as an example to introduce the ERP system realization based on service in detail.The ERP systetm research based on the SaaS pattern and SOA architecture, which is practical signigicance to improve the functions of ERP software. provide a practical of the ERP for the vast number of medium and small enterprises, heighten its core competitiveness, and is helpful to promote the building of information technology on the domestic medium and small enterprises.
