Extensible Information Server 3.0

The task of making data available to business partners and customers presents a variety of challenges. For instance, the content and quantity of data frequently changes (usually by becoming larger and more complex). Or new sources and potential consumers of data emerge, each with different requirements - both in terms of the nature of the data they use and the technology they use to process it. Or access to confidential data must be limited to authorized personnel and users must be isolated from system failures. eXcelon Corporation addresses these issues and more through Extensi... (more)
