....you describe them Well, you shouldn t say what DLLs or object oriented classes each uses. No one will care. Instead, you are more likely to describe the program by the features it has. A feature is a characteristic that is useful in distinguishing programs within a family of related programs [10]) For example, you might say Program1 has features X, Y, and Z. But Program2 is better because it has features X, Q, and R. The reason is that clients have an understanding of their requirements and can see how features relate to requirements. A common way to specify products is by its set of ....

....no preference is given to a particular dimension: all are treated equally. Our research is in software product lines and the synthesis of programs that are members of a product line [2] The hallmark of product lines is its use of features to describe and distinguish product line members [9][11] 22] A feature is a characteristic that programs of a product line can share; distinct programs in a product line are described by distinct combinations of features. Our twist on product lines explores feature modularity. When a program is described by features, we synthesize that program ....

....product line, only pays off in the long run. The way in which the differences between the different products can be managed is the terrain of variability management. The difference of products within a product line could be described with a difference in the required feature set for each product [8]. A feature in this view is an optional or incremental unit of change [13] Features can furthermore be seen as an important entity during the complete software development process, 37] presents an overview why. The notion of features in the software engineering process can be found in the ....

.... adding details [9] The program increments that we consider in this paper are feature refinements modules that encapsulate individual features where a feature is a product characteristic that is used in distinguishing programs within a family of related programs (e.g. a product line) [13]. There are many implementations of feature refinements, each with different names, capabilities, and limitations: lay ers [2] feature modules [17] meta classes [10] collabora tions [23] 24] subjects [14] aspects [18] and concerns [27] More general than traditional modules that ....

....define a family of applications, such as: appl = i(f( appl has features i and f app2 = j(g( app2 has features j and g app3 = i(j(f( app3 has features i, j, and f Thus, by casually inspecting an equation, one can readily determine features of an application. 2. Gdss [22] defines a feature as a product characteristic that users and customers view as important in describing and distinguishing members of a product line. Note that there is a subtle but important confluence of ideas in this model: a function represents both a feature and its implementation. Thus, ....

....changes is unknown, such dependencies would require error prone modifications to pre existing mixins. As a result, each mixin cannot be designed cleanly and independently as composition patterns allow. The need for advanced separation of concerns across the development lifecycle is described in [7], motivated by agent based product line component based development for e Commerce. A development process is proposed that draws together high level analysis and design separation techniques and corresponding, supporting implementation techniques. Composition patterns provide a solution to ....

....the need for separating crosscutting concerns throughout the lifecycle. For example, Griss has proposed a development process for e commerce, componentbased product lines that draws together high level analysis and design composition techniques with supporting implementationcomposition techniques [12]. But this process does not advise on how to map the differing constructs within the combination of approaches that may be used. The difficulties reported in reengineering implementations to take advantage of compositional implementation techniques 5 [22] for which they were not originally ....

FeatureRSEB for aspect oriented product line development proposes a simple method for developing systems with different concerns in mind. [4] This simply suggest using results from the traditional feature based domain analysis as a basis on which aspect oriented techniques are used. Unfortunately, the method does not provide any guidance for creating the product line architecture. In this context, we need clear definitions of main ....
