Application Architecture: Modern Large-Scale Information Processing
Large-scale software engineering applications have structures and functions in common. Identifies those structures and shows how to design a standard application model into which the structures unique to the system in question can be plugged. Construction of such standard models results in simpler and more reliable designs. Material covers architecture of application functions, application support from the programmer's and user's points of view, processing and on-line module design, and emerging trends.
