Abstract:
All (Erp) systems work primarily on the restructuring of companies and institutions and the elimination of old systems, but recently became the concept of integration between systems is common, because building new systems and canceling the old one waste the effort and money There is also a lack of information exchange between ERP and legacy systems in one organization, which results in the lack of reporting of the decision makers.
Old systems can be linked with (Erp) in order to avoid loss of time and effort and reduce the cost of building comprehensive systems. in addition, an integration model can be used to ensure that the integration process has been done correctly, the main objective of this study is to propose a model that can be used for link ERP system with the old systems already in place. In this framework, the model defines the steps necessary for integration between existing systems such as how to identify the points of integration, as well as the selection of appropriate techniques and other steps.
Two systems were selected and then linked using SOA technology to achieve the effectiveness of the proposed model, the implementation results showed a high rate of scalability, compatibility and performance.
the result of the implementation of the model are the integration of the two systems and the exchange of information with high performance using restful technology as the best technique for performance.
