+ Software Engineering Bibliographic Database (SEBD)

+ Software Life Cycle Experience Database (SLED)

The DACS gathers software engineering experience data, as well as documented scientific and technical information. Scientific and Technical Information (STINFO) consists of documented information concerning the state-of-the-art and technology aspects of the computer software field. STINFO sources include technical reports, trade journal publications, proceedings of conference and symposia proceedings, theses, texts, and product descriptions and specifications. This information is stored in computerized databases for easy retrieval.

The Software Engineering Bibliographic Database (SEBD). The DACS Software Engineering Bibliographic Database (SEBD) provides a readily accessible source of comprehensive information on the state-of-the-art in software engineering and channels the information to those able to use it in developing, maintaining, and managing software. The bibliographic collection is composed of texts, technical reports, theses, journal articles, proceedings, and other documents relating to software engineering, reliability, costs, and quality factors, maintainability and other appropriate topics. These documents are obtained from the Defense Technical Information Center (DTIC), from the National Technical Information Service (NTIS), from professional societies, and from publishers. The computerized database facilitates document retrieval by using keywords or any portion of a document citation. A custom search is performed by following the instructions provided. The SEBD is available on CD ROM, or on-line so you can perform your own searches at your convenience.

Software Life Cycle Experience Database (SLED) - There is a real need to collect productivity and failure data on the development, operation, and maintenance of software to support research in the software field. Data is needed which will allow researchers to isolate factors that contribute significantly to the cost, reliability, and quality of the software; to measure achieved reliability; to predict development and maintenance costs; and to track the progress of a software development project. The DACS reviews data sources, contacts the potential data source, and negotiates with the source to secure datasets for inclusion in the DACS Software Life Cycle Experience Database (SLED). When possible, the DACS coordinates the automatic submission of updated data to the DACS by the source. Five datasets are currently contained within SLED.

+ Software Tools

Goel-Okumoto Software Reliability Model. An automated version of the Goel-Okumoto Nonhomogeneous Poisson Process Software Reliability Model which runs on an IBM-PC or compatible under MS-DOS 2.11 or higher. Features include the ability to find maximum likelihood estimators of the parameters defining the model by using either the Newton-Raphson or Muller's method; a goodness-of-fit test based on a Kolmogorov-Smirnovstatistic; estimation of remaining faults, cumulative failures, and reliability; and estimation of the optimal release time based on certain cost criteria.
