Almost all distributed object-oriented systems are partioned into multiple tiers where the presentation tier contains the user interface and the database tier connects the application to databases and other legacy applications. In the middle between them the business logic is provided. Needless to say that the middle tier is the most important part of this architecture. The middle tier must be easy to develop, easy to manage, and easy to change and adapt. Thus, building the middle tier as a monolith is not an appropriate approach. The right approach is to use a component-based approach to separate the concernss within the middle tier. It is the goal of the tutorial to introduce the middle-tier component technology in general as well as the different solutions available today.
Audience:
People interested how to build component-based middle-tier components. Developers intersted in COM+, CORBA 3 and Enterprise JavaBeans.
Required experience:
Attendees should be familar with object-oriented technologies. Knowledge of components and distribution technologies is recommended but not required.
