INCOME/STAR-ProMISE: Process-centered Information System Development

s and future users of a system. This is a point where stagewise models have some of their most important drawbacks as they do not provide facilities for user integration. This criticism led to some new software development paradigms proposed in the mideighties [Agr86]: Concepts like evolutionary system development, prototyping, operational specification, transformational implementation and software reuse influenced software engineering. Yet, there is still an unresolved contradiction between two key requirements to process models: on the one hand, they should result in a structured, well-planned development process; on the other hand, flexibility is required. To bridge this gap, efforts were made to integrate different approaches. In the meantime, new trends became apparent in the field of process modeling: Distribution: Systems may be geographically distributed and are quite frequently integrated in networks. This means that pr

INCOME/STAR: Methodology and Tools for the Development of Distributed Information Systems

INCOME/STAR is an experimental environment for the cooperative development of distributed information systems. This paper presents some of INCOME/STAR's innovative features in the area of information systems engineering: First a new type of high-level Petri nets, so-called Nested Relation/Transition nets (NR/Tnets) , is described. NR/T-nets allow the modeling of concurrent processes and related complex structured objects in distributed business applications. New concepts for entity and relationship clustering were developed to support a stepwise topdown approach for Entity/Relationship based object modeling. Distributed multi-user simulation and prototyping are used for the evaluation and analysis of NR/T-nets and the involved object schema. Finally, ProMISE - an evolutionary process model for information system development - is introduced. A role-based groupware component is part of the INCOME/STAR architecture to support communication, organization and social interaction in developme..

INCOME/STAR: Process Model Support For The Development Of Information Systems

INCOME/STAR is a conception of an integrated environment for the development and maintenance of large, distributed information systems. It extends INCOME, an already existing and commercially available tool for conceptual modelling and prototyping of information systems, by the following features: . design of data and transactions distribution, . physical design, . hypertext interface for design dictionaries, . cooperative system development, . maintenance of large information systems, . project management, . support of different process model standards. In this paper, the architecture of INCOME/STAR is introduced and the main features are surveyed. The paper focuses on one central aspect of INCOME/STAR, the process model support for the development of large information systems. 1 Introduction An increasing demand for software support in various application fields such as industrial automation, business and administration requires individually tailored software solutions and ef..
