| |  | Mehta, Nikunj R. | Towards a Taxonomy of Software Connectors read moreAbstract: Software systems of today are frequently composed from prefabricated, heterogeneous components that provide complex functionality and engage in complex interactions. Existing research on component-based development has mostly focused on component structure, interfaces, and functionality. Recently, software architecture has emerged as an area that also places significant importance on component interactions, embodied in the notion of software connectors. However, the current level of understanding and support for connectors has been insufficient. This has resulted in their inconsistent treatment and a notable lack of understanding of what the fundamental building blocks of software interaction are and how they can be composed into more complex interactions. This paper attempts to address this problem. It presents a comprehensive classification framework and taxonomy of software connectors. The taxonomy is obtained through an extensive analysis of existing component interactions. The taxonomy is used both to understand existing software connectors and to suggest new, unprecedented connectors. We demonstrate the use of the taxonomy on the architecture of a large, existing system. | 2000 |
| | | Garlan, David | An introduction to software architecture read moreAbstract: As the size of software systems increases, the algorithms and data structures of
the computation no longer constitute the major design problems. When
systems are constructed from many components, the organization of the
overall system—the software architecture—presents a new set of design
problems. This level of design has been addressed in a number of ways
including informal diagrams and descriptive terms, module interconnection
languages, templates and frameworks for systems that serve the needs of
specific domains, and formal models of component integration mechanisms.
In this paper we provide an introduction to the emerging field of software
architecture. We begin by considering a number of common architectural
styles upon which many systems are currently based and show how different
styles can be combined in a single design. Then we present six case studies to
illustrate how architectural representations can improve our understanding of
complex software systems. Finally, we survey some of the outstanding
problems in the field, and consider a few of the promising research directions. | 1993 |
