Information Systems Integration, a New Trend in Business

摘要

"Information integration is a key benefit of Enterprise systems. This integration can replace functionally oriented and often poorly connected legacy software, resulting in savings in infrastructure support costs."[l]. The software integration process is complex and it requires a lot of resources to successfully accomplish objectives. Systems integration can be achieved in several ways: integration by entities, integration via portal and integration through business processes. In this paper, we will present some possible ways of integrating systems (integration through business processes and services) and some types of information systems used by companies as well as possible ways of integrating these systems. Systems integration also implies integration of the data handled by these systems, so we will present also some ways of data integration. Finally, we will describe a technique for testing the integrated operation of a software product.
