3. © City University London, Dept. of Computing Distributed Systems / 0 - 3 Nature of the Module  This is a practical module with hands-on experience!  Involves Java Programming.  Theory in the lectures.  Practice in the labs.

4. © City University London, Dept. of Computing Distributed Systems / 0 - 4 What you will learn - I  Problems that occur during construction of distributed systems.  Principles and techniques to solve them.  Components of an infrastructure for distributed systems (OMG/CORBA).

5. © City University London, Dept. of Computing Distributed Systems / 0 - 5 What you will learn - II  OMG - industry consortium. Defines Specifications/interfaces for interoperable software using an object-oriented technology  Practical experience with an OMG/CORBA implementation.  CORBA (Common Object Request Broker Architecture) »standard architecture for distributed object systems. It allows a distributed, heterogeneous collection of objects to interoperate.
