Book Description
Abstract: "A product modeling system (PMS) is a computer integrated development environment for a specific class of advanced products. A well integrated PMS consists of a product model database which is interfaced with CAD-applications that support graphical design of various engineering models. For power plant design, there are functional models, mechanical models, electrical models etc. This paper describes a successful approach to manage the development of a product modeling system for power plant design. The key idea is to store a high-level PMS design specification in the form of an extended entity relationship model in a data dictionary. Most of the source code for the PMS implementation is then generated automatically, using SQL-based source code generators which are easy to develop. Our PMS-development system generates product model database schemas and user interfaces. It also generates high-level database schema related interface modules in the native application development language of a CAD-system. Through these, a CAD application developer has a high-level access to the object structures in the product model database. Using the described approach, we have developed a power plant PMS which is in production at the turbine manufacturer ABB STAL and the power plant engineering company ABB Carbon. The data dictionary design and SQL-based code generation technique seems to be generally applicable and has been used for generating source code implementations in C++, LISP, SQL, and various textual form description languages. The architecture of our PMS-development system is described together with the data dictionary schema and examples of generated source code. We estimate that this software engineering approach reduces system development costs about 5-10 times."

Book Description
This volume presents the proceedings of the First International Conference on Applications of Databases, ADB-94, held at Vadstena, Sweden in June 1994. ADB-94 provided a unique platform for the discussion of innovative applications of databases among database researchers, developers and application designers. The 28 refereed papers were carefully selected from more than 100 submissions. They report on DB applications, for example in air traffic, modelling, maps, environment, finance, engineering, electronic publishing, and digital libraries, and they are devoted to advanced database services, as for example image text and multimedia modelling, fuzzy set based querying, knowledge management, heterogeneous multidatabase management, and intelligent networks.

Book Description
This book is intended as a text for college/university courses, emphasizing CASE tools and group processes. The student is being prepared for a future in which CASE tools, Relational Data Base Management Systems, application generators, group processes, and end-user computing are common. This text is the result of examination and use of the tools and techniques described, the experience of advanced thinkers in the field, and synthesizes the lessons learned in different specialties in a comprehensive manner. Techniques that have traditionally been separated into enterprise modeling, database design, and application design have been integrated into a seamless whole.
