I came across an interesting case study on Database and Information system integration. Here they have highlighted the importance of integration between existing heterogeneous applications and Databases. This article also compares the Enterprise Application Integration process to the traditional integration process.
ABSTRACT
Effective, accurate and timely application integration is fundamental to the successful operation of today’s organizations. The success of every business initiative relies heavily on the integration between existing heterogeneous applications and databases. For this reason, when companies look to improve productivity, reduce overall costs, or streamline business processes, integration should be at the heart of their plans. Integration improves exposure and, by extension, the value and quality of information to facilitate workflow and reduce business risk. It is an important element of the way that the organization’s business process operates. Data integration technology is the key to pulling organization data together and delivering an information infrastructure that will meet strategic business intelligence initiatives. This information infrastructure consists of data warehouses, interfaces, workflows and data access tools. Integration solutions should utilize metadata to move or display disparate information, facilitate ongoing updates and reduced maintenance, provide access to a wide variety of data sources, and provide design and debugging options. In this paper we will discuss integration and a case study on Hybrid Enterprise Integration within a large University using the Calopus system.
