Functional Integration Model A significant portion of IT budgets is spent on the creation and maintenance of business logic. Business logic is code written to perform required business functions in an application. It includes the processes and workflow as well as the data manipulation and interpretation rules. Therefore, it is not surprising that enterprises have found that both presentation and data integration quickly run out of steam as a solution to the integration problems faced in an enterprise.

T With the change in the nature of integration has come an increase in both the range and complexity of integration options. These options include sharing data between applications while ensuring quality and consistency, providing integrated front-end access to applications, bridging applications through workflow, and building new applications that pull together information from existing applications in an innovative manner. The ultimate goal of EAI is to allow an organization to rapidly integrate diverse applications quickly and easily.

4 Data integration should ensure data consistency across applications. Types of Integration 31 database directly may not have the desired effect. Why? In this example the effective checking account balance may be a combination of available balance plus deposits waiting to clear. Banks often place a three- to five-day waiting period on deposited checks. A deposit might be made through the teller or ATM systems. In this instance a deposit requires updating several records as well as performing calculations that would require the replication of business logic in the new application.
