Book Description
The investigation of the methodology for software design prototyping using Ada as a program design language (PDL) involves taking a system engineering approach to software development. A proposal is made to express design characteristics as Ada programs in an effort to provide executability of the design from its earliest specification. This approach is subsequently given more substance by an examination of the methodology from three distinct perspectives: 1) The qualities of an ideal PDL are put forth and Ada is compared with this idealized PDL; Ada compares favorably with this model in most, if not all, areas; 2) The qualities of an ideal software prototype are specified, and the Ada prototype program is measured against this idealized prototype. Ada exhibits a number of characteristics that lend themselves well to the gradual refinement of a prototype program; it also shows itself to be highly supportive of testing and validation of the design as that design matures. It is found that a prototype developed in Ada, using this methodology, offers distinct advantages over the traditional software development; and 3) A step-by-step guide to the use of Ada as a PDL in a design prototyping environment is given. Additional keywords: high level programming languages; test beds; ACSIS (AEGIS Combat System Interface Simulator).

Book Description
"This conference will focus on the user-oriented development of information systems. Against a background of recent concepts for the implementation of distributed systems based on workstation computers, various communicational, organizational and social issues gain increasing importance in the construct ion of computer based information systems. There is an urgent need to integrate end-users and other affected groups into the development process. New strategies for system development are thus needed. " This was the beginning of the Call for Papers to the Working Conference on Prototyping. Working in the fields of user-oriented software construct ion and the analysis of communication problems between developers and users we, that is the GMD team involved in this conference and in preparing its Proceedings, sooner or later came across various new concepts to overcome the problems sketched above. Concepts focusing on the quick construct ion of an operative system such as "rapid prototyping" or concepts aiming at the human and organizational side of the development process such as "Systemeering". Even on a second look, the multitude of different approaches, terms and tools still caused confusion. But despite the differences every concept seemed to have something to do with "Prototyping". This, however, proved to be of little help to us, because the term "Prototyping" itself turned out to be quite "fuzzy". In this obviously confused situation we decided that it was time for a working con ference.

Book Description
Abstract: "The advent of formal, even semi-automated methods of software development directed by mathematical specifications further heightens the necessity for Rapid Prototyping. Rapid Prototyping makes new demands upon software developer processes and practitioners than can be ameliorated by making its technology accessible from within existing technologies, e.g. Ada. Effectiveness considerations dicate both a preprocessor implementation of any entensions/changes to Ada and that functional programming be the prime paradigm to be supported by them. The essence of the functional paradigm is its support for higher-order, function-valued functions to varying levels of generality. A spectrum of levels of support by Ada exists for these different levels of generality, implemented by increasingly sophisticated preprocessors. This leads to the conclusion that Ada is well-designed for adaptability to emerging software development methods. This, and the high level of support we have achieved for the functional paradigm leads to the further conclusion that further R & D in the adaptation of Ada to different paradigms (e.g. object- orientation) is now warranted."

Book Description
Excerpt from From Prototype to Efficient Implementation: A Case Study Using Setl and C This paper reports on an ongoing experiment in the use of very high level languages (vhlls) for software design and prototyping (see Bul] for a recent survey of the practice of Software Prototyping). The work of the nyuada group revolves around the use of setl, a vhll whose most salient feature is the use of constructs taken from the mathematical theory of sets. Using setl, our group was able to construct the first validated translator for Ada(R). The first ada/ed system, validated in April 1983, was intended to serve as an operational definition of Ada and as a very abstract design for an Ada compiler, and as such was no more than an executable definition. (and barely executable at that: a few source lines of Ada per second of cpu time on a vax/780). Ada/ed proved nevertheless to be a useful teaching tool, and an excellent testbed for the use of vhlls in software prototyping; thanks to theexclusive use of setl, it proved possible to construct a full translator for Ada in about 16 person-years, within a typically unstructured academic environment, without any rigorous Software Engineering procedures, and no design documents other than the program itself [kr1]. It must be added that roughly half of those 16 years were spent in tracking language changes between preliminary Ada and ansi Ada, a period in which the prototype did indeed evolve with shifting requirements!

Book Description
In November 1989 we organised a workshop on software re-use, inviting members of the leading research teams across Europe. In retrospect, we realise that we missed a few research teams out, but nevertheless we did have a very fruitful workshop. This book is the outcome of that meeting. Prior to the workshop, teams submitted short position papers, and at the workshop made very short presentations of these. Most of the time was spent in four parallel sessions, and the reports of these sessions are given in Chapter 2. After the workshop we invited the attendees to revise and resubmit their papers in the light of the workshop, and it is these updated papers that appear in Chapter 4 onwards. The papers are in alphabetical order of first author. To complete this text we have added an introduction to software re-use as a first chapter-this was prepared by Liesbeth Dusink. We have added a comprehensive bibliography as Chapter 3, merging the bibliographies accumulated at Delft and at Brunei. To be able to organise the workshop we were sponsored by SERC, the Software Engineering Research Centre in Utrecht, Netherlands.
