combining software components, subsystems, etc., into a single
application system.
3. The process of identifying, collecting organising,
analysing and representing a domain model and software
architecture from the study of existing systems, underlying
theory, emerging technology and development histories within
the domain of interest.
4. The analysis of systems within a domain to discover
