Q5) (A)

Explain Client/Server Software Engineering. 

·       Two approaches are most commonly used

o   An evolutionary paradigm that makes use of event-based and/or object-oriented software engineering

o   Component-based software engineering that draws on a library of COTS (commercial off-the-shelf) and in-house software components.

·       Client/server systems are developed using the classic software engineering activities - analysis, design, construction and testing

·       Instead of viewing software as a monolithic application to be implemented on one machine,

o   the software has several distinct subsystems that can be allocated to the client, the server or distributed between both machines

·       User interaction/presentation subsystem

o   This subsystem implements all functions that are typically associated with a graphical user interface

·       Application subsystem

o   This subsystem implements the requirements defined by the application

·       Database management subsystem

o   This subsystem performs the data manipulation and management required by an application

o   Data manipulation and management may be as simple as the transfer of a record or as complex as the processing of SQL transactions.
