AIA Enterprise Business Services - Conceptually, what do they represent?
By Annaji Garimella on Jul 23, 2008
The AIA Enterprise Business Services (EBS) represent the core business functions of an enterprise as they interact with the wider ecosystem of enterprises as part of day to day business interactions. They are not web services exposed by any business software application implemented in an enterprise.
Let me elaborate further. In any enterprise, we always find multitude of software applications implemented. This is mostly by design. Running a business is complicated and it is challenging to keep up with the competitors. In their quest to excel, enterprises seek best of the breed software applications evaluating their core functionalities. Thus an enterprise ends up with different software applications catering to Customer Management, Product Management, Asset Management, Order Management, Financial Management and so on. The stove pipes of applications are more narrower in scope, in reality.
The web services or APIs exposed by these software applications are granular in nature and represent their core functionalities. These applications need to be integrated in order for the enterprise to carry out the core business functions. For each of these business functions or tasks to be accomplished, multiple applications with their granular services need to participate.
The AIA Enterprise Business Services, representing these business functions or tasks, mediate the invocation of the granular web services between various participating applications.
Needless to say, the payloads of the AIA Enterprise Business Services are Enterprise Business Messages (EBM) and these represent the canonical data models of the industry in which the enterprise is doing business. They are not hostage to the participating application data models.
