Component-Based Development (CBD) is an effective approach to develop software effectively and economically through reuse of software components. Model Driven Architecture (MDA) is a new software development paradigm where software is generated by a series of model transformations. By combing essential features of CBD and MDA, both the benefits of software reusability and development automation can be achieved in a single framework. In this paper, we propose a Component-based P Platform Independent Model (CB-PIM) and a UML profile for specifying component-based design in MDA framework. We suggest mapping rules to transform CB-PIM into Platform Specific Models (PSM). Once components are specified with our profile at the level of PIM, they can be automatically transformed into PSM and eventually source code implementation. [ABSTRACT FROM AUTHOR]

A Product Line (PL) is a set of products (applications) that share common assets in a domain. Product line engineering (PLE) supports the systematic development of a set of similar software systems by common and distinguishing characteristics. Core assets, the common assets, are created and instantiated to make products in PLE. Model Driven Architecture (MDA) emphasizes its feasibility with an automatically developing product. Therefore, we can get the advantages of two paradigms, PLE and MDA, as core assets are represented as PIM in MDA with a predefined automatic mechanism. The PLE framework in the PIM level has to be interpreted by MDA tools. However, we do not have a standard UML profile for representing core assets. The research representing the PLE framework is not enough to automatically make core assets and products. We represent core assets in the PIM level in terms of architecture, components, and decision models. Core assets are specified with our profile at the level of PIM, where they can be automatically transformed and instantiated. The method of representing the framework with PLE and MDA is used to improve productivity, applicability, maintainability and quality of products. [ABSTRACT FROM AUTHOR]

Component based development (CBD), product line engineering (PLE), and model driven architecture (MDA) are representative approaches for software reuse. CBD and PLE focus on reusable assets of components and core assets, MDA focuses on transforming reusable models into implementation. Although these approaches are orthogonal, they can be integrated into a comprehensive and extremely effective framework for software development. In this paper, we first present our strategies of integrating CBD, PLE and MDA, and propose an integrated process that adopts reuse engineering and automation paradigm. By applying the proposed approach, it becomes feasible to semi-automatically develop a number of applications in a domain. [ABSTRACT FROM AUTHOR]

Component-Based Development (CBD) is gaining popularity as an effective reuse technology. Components in CBD are mainly for interorganizational reuse, rather than intra-organizational reuse [1]. One of the common forms of reusing commercial-off-the-shelf (COTS) components is to acquire and customize them for each application. Therefore, components must be developed with consideration of commonality and variability in a domain in order to increase the reusability and applicability [2]. One effective factor in determining the quality of components is how precisely the variability is modeled and how effective customization mechanisms are provided. COTS components often come in binary and blackbox form, therefore modifying the source code or re-linking object code with library are forbidden. However, much of current approaches to component customization are directed towards tailoring whitebox components, i.e. source code is modified. In this paper, we present a comprehensive set of techniques to realize variability into blackbox components and to provide effective interface-based customization mechanisms. Maintanbility, applicability and reusability can be enhanced by using the mechanism. [ABSTRACT FROM AUTHOR]
