Analyzing Alternative Architectural Designs
To evaluate the quality of an architecture the design should be accomplished effectively. Basically there are two different approaches for the analysis of alternative architectural design as given below:
1. An Architecture Trade off analysis Method: The software engineering Institute has developed an architectural trade off analysis method (ATAM) various design analysis activities performed iteratively are:
a. Collect scenarios of the system.
b. Elicit requirements constraints and environment description.
c. Describe the architectural styles patterns that have been chosen to address the scenarios and requirements.
d. Indentify the sensitivity of quality attributes to various architectural attributes for a specific architectural style.
Based on the results of steps 5 and 6 architectural alternatives may be eliminated, modified and represented in more detail and then the ATAM steps are reapplied.
2. Qyabtutatuve Guidance for Architectural Design: Asada and his colleagues suggested a number of quantitative techniques for architectural design and is the complementary approach of the ATAM approach. Asada proposed a number of simple models so that a designer can determine the degree to which a particular architecture meets predefined goodness criteria. These criteria encompass the quality attributes that are reliability, performance, security maintainability, flexibility, testability, portability, reusability, etc. There are two models of Asada.
a. Spectrum Analysis Design Selection Analysis
b. The first model, called spectrum analysis assesses an architectural design on a goodness spectrum form the best to worst possible designs.
c. Design selection analysis is another model that requires a set of design dimensions to be defined. The proposed architecture is then assessed to determine the number of design dimensions that it achieves when compared to an ideal best case system.
3. Complexity of the Architecture
To evaluate the overall complexity of a software architecture, the interdependencies of modules are considered. These interdependencies are seen as information control flow into the system. Zhao has suggested 3 dependencies:
a. Sharing dependencies represent dependence relationships among consumers who use the same resource or producers who produce for the same consumers. For example for two components u and if u and v refer to the same global data then there exists a shared dependence relationship between and v.
b. Flow dependencies represent dependence relationships between producers and consumers of resources. For example for two components u and v if u must complete before control flows into v ( prerequisite ) or if u communicates with v by parameters, then there exists a flow dependence relationship between u and v.
c. Constrained dependencies represent constraints on the relative flow of control among a set of activities. For example for two components u and v, u and v cannot execute at the same time ( mutual exclusion) then these exists a constrained dependence relationship between u and v.
