System architecture marks the end of the systems design phase of the SDLC. Recall that
back in the systems analysis phase, all functional primitives were identified and documented
with process descriptions. The objective then was to identify the system’s functions
and determine what each logical module would do, without attempting to
determine how that function would be carried out. Moving from analysis to design
tasks, the development process continued with consideration of output and user interface
design, data design, and system architecture issues. Now, based on a clear definition
of system requirements and design, software applications can be developed, documented,
and tested as part of the systems implementation phase of the SDLC, which is
described in Chapter 11, Managing System Implementation.
Developers must also consider system management and support tools that can monitor
system performance, deal with fault management, handle backup, and provide for
disaster recovery. These topics are covered in detail in Chapter 12, Managing Systems
Support and Security.
