How do you organize an "industrial strength" one semester educational programming project for up to 200 second year students? This paper reports on four years of experience with such projects at the University of Paderborn and the University of Braunschweig. Key properties of our project design are: starting with an existing large application, regular hard deadlines with peer reviews and presentations to a large audience, working in groups, applying project and configuration management tools, a standard system architecture with interchangeable components and competing software agents, quality assurance and standard conformance testing through final overall system integration spanning all groups, and exposure to real-world project threats.

This abstract presents an approach to semi-automatically detect pattern instances and their implementations in a software system. Design patterns are currently best practice in software development and provide solutions for nearly all granularity of software design and makes them suitable for representing design knowledge. The proposed approach overcomes a number of scalability problems as they exist in other approaches by using fuzzy logic, user interaction and a learning component.

A method and a corresponding tool is described which assist design recovery and program understanding by recognising instances of design patterns semi-automatically. The approach taken is specifically designed to overcome the existing scalability problems caused by many design and implementation variants of design pattern instances. Our approach is based on a new recognition algorithm which works incrementally rather than trying to analyse a possibly large software system in one pass without any human intervention. The new algorithm exploits domain and context knowledge given by a reverse engineer and by a special underlying data structure, namely a special form of an annotated abstract syntax graph. A comparative and quantitative evaluation of applying the approach to the Java AWT and JGL libraries is also given.

This paper proposes to use SDL block diagrams, UML class diagrams, and UML behavior diagrams like collaboration diagrams, activity diagrams, and statecharts as a visual programming language. We describe a modeling approach for flexible, autonomous production agents, which are used for the decentralization of production control systems. In order to generate a (Java) implementation of a production control system from its specification, we define a precise semantics for the diagrams and we define how different (kinds of) diagrams are combined to a complete executable specification.

it turns collaboration diagrams in a powerfull and easy-to-read visual programming construct. However, a single collaboration diagram is usually not expressive enough to model complex operations performing several modifications at different parts of the overall object structure. Such series of modifications need several collaboration diagrams to be modeled. In addition, there may be different situations where certain collaboration diagrams Figure 1 The Fujaba Environment Concepts \t \t \t <
