what is jackson structured develepment?? and how is it
different from OMT??
Answer Posted / vijith
Jackson structured development (JSD) is anothermature
methodology which has a different style than SA/SD or OMT.
The JSD methodology was developed by Michel Jackson and is
especially popular in Europe.JSD
does not distinguish between analysis and design and instead
lumps analysis and design as specification.JSD divides system
development into two stages
(1)Specification
(2)Implementation.
The OMT Methodology: System Design
The ESA terminology for system design is Architectural Design.
The object-oriented viewpoint introduces no new insights
into system design, but system
design is included in OMT for compete coverage of the
development process.
The steps taken during system design are:
•Organize the system into subsystems (top-level components).
•Identify concurrency inherent in the problem.
•Allocate subsystems to processors and tasks
(processes/threads).
•Choose the basic strategy for implementing data stores in
terms of
data structures, files and databases.
•Identify global resources and determine mechanisms for
controlling
access to them.
•Choose an approach to implement software control:
•use the location within the software to hold the state, or
•directly implement a state machine, or
•use concurrent tasks.
•Consider boundary conditions (initialization, termination,
failure).
•Establish trade-off priorities (speed, memory, portability,
...).
