A component-based product line architecture for workflow management systems

This paper presents a component-based product line for workflow management systems. The process followed to design the product line was based on the Catalysis method. Extensions were made to represent variability across the process. The domain of workflow management systems has been shown to be appropriate to the application of the product line approach as there are a standard architecture and models established by a regulatory board, the Workflow Management Coalition. In addition, there is a demand for similar workflow management systems but with some different features. The product line architecture was evaluated with Rapide simulation tools. The evaluation was based on selected scenarios, thus, avoiding implementation issues. The strategy that has been used to populate the architecture and experiment with the product line is shown. In particular, the design of the workflow execution manager component is described

Properties for Component Model: The definition Perspective

The presence of a large number of component models to date should be able to offer software developers a wide variety of component models -- which they can easily choose from -- for their software development projects. However, the opposite situation is currently observed, where the presence of many component models has caused difficulties in making the selection. Lack of properties or characteristics that can be used as a basis to perform objective comparison between the existing models is believed to have caused the difficulties. In this paper, a list of component model properties is derived by thoroughly examining the available component model definitions. Results from a comparative analysis performed on six component models using the properties show that the properties enable a more objective comparison between the existing component models to be performed

A Brief Survey on Product Derivation Methods in Software Product Line

Product Derivation represents one of the main challenges that a Software Product Line (SPL) faces. Deriving individual products from shared software assets is a time-consuming and an expensive activity. Until now, only few works addressed, in a limited context, a partial evaluation of a reduced number of proposed derivation approaches. The main objective of such studies was the comparison of a proposed approach regarding two or three approaches. The purpose of the study reported in this paper is to set up a framework oriented to evaluate and compare existing SPL derivation approaches. The proposed framework uses a number of criteria which help understanding the capabilities and highlight the strength and the weakness of each SPL derivation approach

Entwicklungsmethodiken zur kollaborativen Softwareerstellung – Stand der Technik

Die weltweit wachsende Nachfrage nach Unternehmenssoftware erfordert immer neue Methoden und Formen der Zusammenarbeit (Kollaboration) bei der Softwareerstellung. Zu diesem Zweck untersucht und vergleicht dieses Arbeitspapier existierende Vorgehensmodelle und deren Evolution. Zusätzlich werde erste Ansätze zur kollaborativen Softwareerstellung vorgestellt und ihre Eignung für ein kommerzielles Umfeld analysiert. Die Arbeit verwendet hierzu einen eigenen Vergleichsrahmen, der u.a. auch so genannte "Kollaborationspunkte“ in Betracht zieht, d.h. Aktivitäten im Prozess an denen das Einbinden mehrerer Entwickler und/oder Anwender vorteilhaft ist. Die Erkenntnisse aus der vergleichenden Analyse des Stands der Technik werden schließlich dazu verwendet, Defizite existierender Ansätze aufzuzeigen und Anforderungen für unterstützende Werkzeuge abzuleiten

A Reference Framework for Variability Management of Software Product Lines

Variability management (VM) in software product line engineering (SPLE) is introduced as an abstraction that enables the reuse and customization of assets. VM is a complex task involving the identification, representation, and instantiation of variability for specific products, as well as the evolution of variability itself. This work presents a comparison and contrast between existing VM approaches using qualitative meta-synthesis to determine the underlying perspectives, metaphors, and concepts of existing methods. A common frame of reference for the VM was proposed as the result of this analysis. Putting metaphors in the context of the dimensions in which variability occurs and identifying its key concepts provides a better understanding of its management and enables several analyses and evaluation opportunities. Finally, the proposed framework was evaluated using a qualitative study approach. The results of the evaluation phase suggest that the organizations in practice only focus on one dimension. The presented frame of reference will help the organization to cover this gap in practice.Comment: 24 page

Integration of document representation, processing and management

This paper describes a way for document representation and proposes an approach towards an integrated document processing and management system. The approach has the intention to capture essentially freely structured documents, like those typically used in the office domain. The document analysis system ANASTASIL is capable to reveal the structure of complex paper documents, as well as logical objects within it, like receiver, footnote, date. Moreover, it facilitates the handling of the containing information. Analyzed documents are stored by the management system KRISYS that is connected to several different subsequent services. The described integrated system can be considered as an ideal extension of the human clerk, making his tasks in information processing easier. The symbolic representation of the analysis results allow an easy transformation in a given international standard, e.g., ODA/ODIF or SGML, and to interchange it via global network
