Abstract
During software development and maintenance, an engineer needs to be able to answer a variety of questions about the software in a very short time, many of which relate to information generated during the specification and design phases. In the current state of practice, this is sometimes not possible. Any solution to this problem should allow group usability of information, automatic creation of information in target form from the structure in which it was created and selective fast access. This paper presents a framework for doing so based on integrated modeling of software, use of automatic information extraction tools, web technology and databases. We then describe demonstrations that indicate that such a solution can be produced at a reasonable cost in an error-free manner and would meet the concerns of safety analysts about the sensitivity of safety analysis information.
