Summary

Subject Area
Business objects handle the rules to process information correctly - the business logic required for an application. The .NET framework provides new mechanisms to easily locate business objects in different physical locations (i.e. stored on different computers) and supports standards like Web Services which mean .NET business objects are able to inter-operate with applications coded in many other languages and running on different operating systems. Both these abilities add huge value in distributed programming.
