|TITLE||Advanced Client/Server Computing and Distributed Databases|
|UM LEVEL||03 - Years 2, 3, 4 in Modular Undergraduate Course|
|DEPARTMENT||Computer Information Systems|
|DESCRIPTION||The overall aim to this unit is to reinforce and introduce to students principles, techniques and methodologies for the deployment and movement of the computational artefacts (eg. data and programs) across state of art computer infrastructures. This unit should provide an essential background for further Client/Server model applications which deploy objects and use an object oriented approach for interoperability among different platforms.
One accent of this unit is given to deep understanding of Client/Server model mainly regarding connection and communication issues between the Client and Server. Three tier architecture is also applied namely to the Server (middle tier) handling of a database (third tier).
Client/Server model: single and multiple (heterogeneous) platforms. Connection issues (connectionless, connection oriented). Socket structure and programming. Programming interface to communication protocols. Addressing issues, static and dynamic address binding, using name servers. Client software design. Server software design. Case studies of four basic types of servers. Multiprotocol and Multiservice Servers. Design Strategies – Concept of Multi-tier Architecture. Design concepts using various technologies including access to RDBMS. Server connectivity to databases. ODBC model. Accessing databases using SQL. Monolithic and Object based Client/Server architectures. Client – Server Objects Interoperability. DCOM (Distributed Common Object Model) - basic features, concept of interfaces, automation principles.
Another accent of this unit is the study of distributed data and functions, across computer network. The theory, design, specification, implementation, and performance of distributed database systems are pursued. Also the inherently different set-ups for multidatabase are emphasized.
Topics include principles of naming and location, atomicity, query processing and optimisation, resource sharing, concurrency control and other synchronization, recovery procedures, deadlock detection and avoidance, security, distributed access and control, distributed systems design, consistency and fault tolerance.
