TAILIEUCHUNG - Concepts in Configuration Management Systems

FSA has made the Direct Loan Program more user-friendly for schools and students by (1) using Web sites to disseminate and collect information and forms, (2) implementing a new information system that originates and disburses Direct Loans to students faster, and (3) providing staff in regional offices to assist Direct Loan schools. Direct Loan schools indicated that FSA’s Web sites are effective in helping them administer the program and have simplified the process for Direct Loan borrowers. For example, Direct Loan borrowers are able to complete and sign their loan applications online and view information about their loans when they enter repayment. Despite schools’ satisfaction with FSA’s Web sites,. | Concepts in Configuration Management Systems Susan Dart Software Engineering Institute Carnegie-Mellon University Pittsburgh PA. 15123-3890 USA dart@ Sponsored by the . Department of Defense Abstract There has been considerable progress concerning support for software configuration management CM in environments and tools. This paper s intent is to highlight the user concepts provided by existing CM systems. These are shown as a spectrum. In the spectrum concepts are seen as extensions to or generalizations of other concepts. There is difficulty associated with extracting concepts from CM systems since there is no commonality in terminology concerning CM functionality throughout the software engineering community and many CM systems implement variations on concepts. As a result each concept presented is described as it exists in one particular CM system. A part of highlighting the concepts involves discussing the scope of issues important to users of CM systems. No single CM system provides all the functionality required by the different kinds of users of CM systems. Rather each CM system addresses some part of the spectrum of concepts. To complete the report the CM capabilities of the systems used as examples are briefly described. 1 Introduction It becomes evident upon surveying existing configuration management CM systems that there has been progress concerning support for software CM in environments and tools. This is evident from the spectrum of concepts provided by CM systems. The intention of this paper is to highlight that spectrum. To begin a broadened definition of CM and a CM system are given along with a typical CM scenario. Definition of Configuration Management Software CM is a discipline for controlling the evolution of software systems. Classic discussions about CM are given in texts such as 3 and 4 . A standard definition taken from IEEE standard 729-1983 16 highlights the following operational aspects of CM Identification an .
