Numerical algorithms, glossy programming strategies, and parallel computing are usually taught serially throughout diverse classes and varied textbooks. the necessity to combine recommendations and instruments frequently comes merely in employment or in study - after the classes are concluded - forcing the coed to synthesise what's gave the impression to be 3 self reliant subfields into one.

Example text

The goals and the design problems are not all known up-front when architecture design activities begin. Many of the design problems are discovered during design. The process of architecture design can be problemdriven if one does not understand the problem domain very well or it can be solution driven if the solutions the problems are well-known to the architects, it is usually both. The communication of the design contexts, design problems and potential solutions across different architecture disciplines is an essential part of bridging the knowledge gap between them.

A CLASSIFICATION FOR ARCHITECTS Having held a number of architectural roles ourselves, and observed architects at work in many other organizations, we have found that architects fall into one of three broad groups: enterprise architect, application architect and infrastructure architect. These three groups encompass all of the architectural roles that we have seen in practice. To help explain the differences between these roles, we classify them along two axes, namely their business/technology focus (the extent to which they focus on the problem domain as opposed to the solution domain), and the breadth of their architectural portfolio (the number of systems that they have architectural responsibility for).

These artifacts, to a great extent, allow making changes in the large-scale and complex software systems possible without damaging the integrity of the architecture. Once one or the other architecture disappears and following a similar argument to that of (Bennet & Rajlich, 2000), the system will be difficult to evolve and enters the stage of servicing (also referred to as maturity by Lehman) (Bennet & Rajlich, 2000). At the servicing stage, only small tactical changes would be possible. For the business and the enterprise, the software is likely to be no longer a core product and the cost-benefit of the change becomes marginal.
