摘要:

AbstractE. Burton Swanson summarizes and explains his typology of software maintenance (corrective, adaptive, and perfective), and describes his research on maintenance. His two major projects have been the large DPMA study done in 1977 with Bennet P. Lientz, and the in‐depth intensive study of twelve sites done a bit over a decade later with Cynthia M. Beath. Professor Swanson includes some of his views of the current situation and future in software maintenanc

摘要:

AbstractThe destiny of legacy software is a relevant economic problem. Many companies are experiencing the friction that legacy systems oppose to the change and growth of their business. Nevertheless, these systems cannot be simply discarded and replaced with new ones developed according to the new organization requirements. Existing systems record a great deal of knowledge and expertise used to set up solutions to real problems in different application domains and it is imperative that this knowledge must not be lost, partly because it may not be recorded anywhere else than in the code.This paper discusses the problems related to the modularization of legacy systems, with the emphasis being placed on the automation of code scavenging. It is argued that a balance must be struck between the modularization of legacy code, and the production of reusable, easy‐to‐evolve modules. The paper provides a framework for examining system modularization methods and identifies a set of attributes that define their quality. An overview of modularization techniques is presented, and an evaluation is made to assess their strength and identify and understand their major limitations. Finally, an attempt is made to identify techniques and tools that are nature enough to be transferred from research laboratories to indus

摘要:

AbstractThis paper gives an overview of the software maintenance process of Hitachi Software Engineering (HSK) Co., Ltd in Japan‐including its success and failure cases. It discusses HSK's software processes, issues, use of specific tools and techniques such as IMOZU diagrams, and approaches in solving problems. These include the requirement capturing process, reverse‐engineering techniques, environmental changes, change management, and project management. By discussing actual project experiences, we point to certain lessons and their implications for research in software maintenance. We also present the latest re‐engineering CASE tools, such as RE‐ENGINEERING and SEWB3, used
