| Aims |
|
At the completion of this course, the students will be able to:
a) have a good understanding of the importance of component wiring models b) completely understand the object models discussed, with their common and specific features c) know how to use programming languages (C++, Java, Component Pascal) to implement COM, CORBA, and Java Beans, and Component Pascal components |
