This lesson introduces some of the most important concepts for the technological aspects of eBusiness applications, including client/server and multi-tier architecture, design patterns, middleware and the role of XML, in particular for web services.
Objectives:	You will be able to use the concept of architecture for distributed applications. You will understand the most important technical terms of reusable application design. In particular, you will be familiar with the technical terms of object-oriented middleware and understand the concept and role of XML in web-based applications.
