Enterprise business integration can occur at 3 different levels within the IT system: data, applications, business processes, and user interaction. Many technologies and tools matched with one of these categories.

But, as we shall see, there is a trend in the industry toward IT applications that support various levels of integration and is therefore significant for designing an integrated framework that can integrate all levels of the enterprise data integration process.

Data Integration offers the prospect of a combination of corporate data that is paved all the way through the company. Combining these views can be built using a mix of different methods and technologies.  Perhaps the physical view of data that has been limited from a variety of different data sources and incorporated into a data warehouse integrated or operational data store.

Application integration provides a unified view of business applications that are inside or outside the company. This unified view obtained by supervising and regulating the flow of events (transactions, messages, or data) between various enterprise applications. Integration of applications, such as data integration, providing a diversity of skills and technology implementation depends on the needs of the integration project.

Business Process Management offers a combined view of the company’s processes. Business integration software facilitates programmers to evaluate, model, and simulate business processes and their underlying activities. Business management software then executes and oversees this process using the methodology underlying application integration.
