Component-Based Software Engineering

Component-based software engineering (CBSE) is concerned with the devel- ment of software-intensive systems from reusable parts (components), the dev- opmentofsuchreusableparts,andthemaintenanceandimprovementofsystems by means of component replacement and customization. Although it holds c- siderable promise, there are still many challenges facing both researchers and practitioners in establishing CBSE as an e?cient and proven engineering dis- pline. Six CBSE workshops have been held consecutively at the most recent six International Conferences on Software Engineering (ICSE). The premise of the last three CBSE workshops was that the long-term success of component-based development depends on the viability of an established science and technology foundation for achieving predictable quality in component-based systems.

The goal of the CBSE 2004 symposium was to discuss and present more complete and mature works, and consequently collect the technical papers in published proceedings. The response to the Call for Papers was beyond expectations: 82 papers were submitted. Of those 25 (12 long and 13 short) were accepted for publication. In all 25 cases, the papers were reviewed by three to four independent reviewers. The symposium brought together researchers and practitioners from a variety of disciplines related to CBSE.
