They are successfully used as the underlying mathematical concept in various application domains. In all these domains tools are developed that store, retrieve, manipulate and display graphs as underlying data structures, despite of the fact that in most cases these graphs have a different name such as object diagrams, (meta) class diagrams, hyper documents, semantic webs etc. It is the purpose of this workshop to summarize the state of the art of graph-based tool development, bring together developers of graph-based tools in different application fields and to encourage new tool development cooperations. Motivation Graphs are an obvious means to describe structural aspects in various fields of computer science. They have been successfully used in application areas such as compiler compiler toolkits, constraint solving problems, generation of CASE tools, pattern recognition techniques, program analysis, software engineering, software evolution, software visualization and animation, and visual languages. In all these areas tools have been developed that use graphs as an important underlying data structure. Since graphs are a very general structure mechanism, it is a challenge to handle graphs in an effective way. Using graphs inside tools the following topics play an important role: efficient graph algorithms, empirical and experimental results on the scalability of graphs, reusable graph-manipulating software components, software architectures and frameworks for graph-based tools, standard data exchange formats for graphs, more general graph-based tool integration techniques, and meta CASE tools or generators for graph-based tools. The aim of the workshop on graph-based tools (GraBaTs) is to bring together developers of all kinds of graph-based tools in order to exchange their experiences, problems, and solutions concerning the efficient handling of graphs. The GraBaTs workshop is, therefore, of special relevance for the http://link.springer.de/link/service/series/0558/tocs/t2505.htm 1st Intl. Conference on Graph Transformation (ICGT) which hosts GraBaTs as a satellite event: In many cases the application of graph transformation technology requires the existence of reliable, user-friendly and efficiently working graph transformation tools. These tools in turn have to be built on top of basic services or frameworks for graphs, which are the main topic of our workshop. Today, several graph transformation tool implementations have emerged which do not share any basic graph services (e.g. for graph pattern matching or graph layout purposes) and which implement rather different graph concepts and graph transformation approaches. Some of these tools - as a kind of survey of the state of the art - were presented in a special session, which is part of the main conference as well as of this satellite workshop. The presented tools are AGG, DiaGen, Fujaba, GenGED, and UPGRADE. The GraBaTs workshop was held for days. Its schedule contained in addition to the afore-mentioned session on graph transformation tools, an invited talk by Tiziana Margaria (University of Dortmund, Germany) on ETI, an electronic tool integration platform where graph-based tools will play an important role. Apart from four sessions with presentations of 15 accepted papers (out of 19 submissions) on various graph-based tools and tool-relevant topics, a successful discussion ''Towards Standard Exchange Formats for Graph and Graph Transformation'' took place. Workshop Issues The workshop aims at bringing together tool developers from different fields, dealing with graphs from different perspectives. In the following, we give an overview on the most important perspectives. Meta-modeling by Graphs For a long time the syntax and static semantics of most visual modeling or programming languages was only defined by means of characteristic examples and informal descriptions. To improve this situation the visual language community invented grammar-based formalisms for the definition of the syntax of their languages, such as constraint grammars, graph grammars, relational grammars, etc. Unfortunately it turned out that the grammar-based definition of visual languages is rather complicated compared with the meta-modeling approach developed in parallel. The Meta-modeling approach for the definition of visual languages uses a combination of class diagrams (ER-diagrams, etc.) and predicate logic expressions (Z, OCL, etc.) to define the syntax and static semantics of visual languages. It became popular with the standardization of the OO-modeling language UML and is used by various meta-modeling (meta-CASE) tools which are able to generate domain-specific CASE tools. The so-called MOF approach (Meta-Object Facility) is one attempt to come up with a meta-modeling standard. Despite of its limited expressiveness (compared with ER diagrams or UML class diagrams) MOF builds the basis for the formal definition of UML and other visual languages. All meta-modeling approaches used nowadays have one common property: they offer graph-like diagrams for the definition of the structure (syntax) of graph-like diagram languages. Therefore, meta-modeling is in fact the formal definition of graph languages by means of graphs which are instances of "meta" graph languages. As a consequence, meta-CASE tools are a special class of graph-based tools, which need at least basic services for storing, visualizing, and analyzing graphs. Graph Visualization Facilities for visualizing graphs are needed by all kinds of graph-based tools, independent of the fact whether they are e.g. used for meta-modeling or rule-based programming purposes. Furthermore, graph visualization techniques are the most important means for visualizing various aspects of softwarearchitectures, the dynamic behavior of running systems, their evolution history, and so forth. Software components developed for these purposes usually have to deal with huge graphs and need services for making these graphs persistent, for introducing abstractions based on hierarchical graph models, for computing reasonable graph layouts (efficiently), and for displaying graphs effectively using "fish-eye-techniques" and the like. And last but not least, graph visualization techniques are often employed for teaching purposes in computer science courses on "data structures and (graph) algorithms". To summarize, almost all kinds of graph-based tools urgently need efficiently and effectively working graph visualization services, whereas graph visualization tools may profit from research activities on graph query and graph transformation engines for the computation of graph abstractions or views. We, therefore, hope that this workshop encourages researchers to start new cooperations, such as adapting graph visualization tools to the needs of graph manipulation tools or exploiting graph manipulation and transformation techniques to compute sensible abstractions of huge graphs. Graph Queries and Graph Algorithms Most, if not all, graph-based tools use to a certain degree software components (libraries, subsystems, etc.) for executing graph queries and/or various kinds of standard graph algorithms. For example, graph transformation tools rely on rather sophisticated means for computing graph matches (rule occurrences) and graph-based reverse engineering tools need rather powerful query engines for determining critical substructures of software architectures. On the other hand, quite a number of database management systems have already been developed using graphs (networks of related objects) as the underlying data model and offering query languages based on graph path expressions or even graph transformations. Vice versa, graph transformation languages like PROGRES are not only used for specifying and visualizing graph algorithms, but incorporate many elements of database query languages such as means for the construction of indexes, the materialization and incremental update of views, etc. Therefore, we like to encourage tool developers again to start cooperating across the boundaries of research areas. Graph Transformation Graph transformation means the rule-based manipulation of graphs. Several graph transformation approaches have emerged which differ w.r.t. to the underlying kind of graphs as well as in the way how rules are applied to graphs, i.e. graph transformation takes place. The kind of graphs used by these tools include labeled, directed graphs, hypergraphs, and graph structures. Their rules, the basic means to manipulate graphs, differ w.r.t. to the formal definition of their semantics, the way how occurrences (matches) are searched for, and how matching rules are applied eventually. In tools, graph transformation is applied to visual languages, specification, code generation, verification, restructuring, evolution and programming of software systems, etc. Developers of graph transformation tools may profit from other workshop participants concerning more efficient realizations of basic functionality, while developers of other graph-based tools might find the graph transformation paradigm attractive to implement certain graph manipulations. The workshop may also provide insights to apply these tools to other application domains. Common Exchange Formats for Graphs and Graph Transformation To support interoperability between various graph-based tools, several initiatives on the development of common exchange formats for graphs have been founded. These formats are all based on the extensible markup language XML developed to interchange documents of arbitrary types. Preceding events like three subgroup meetings of the EU Working Group APPLIGRAPH, a Workshop on Standard Exchange Formats, and a satellite workshop of the 8th Intl. Symposium on Graph Drawing (GD 2000)discussed various ideas which are currently converging to one format being GXL. During the GraBaTs workshop a further discussion round on this topic was organized focusing especially on graph layout and graph attributes. Another topic of interest for this discussion is an exchange format for graph transformation systems called GTXL, which is under development and which will be built on top of GXL.

The combination of workflow audit trails with data warehouse technology and operational business data allows for complex analyses that can support managers in their assessment of an organization’s performance. The increasing maturity of business process management and data warehouse systems enables the design and development of advanced process-oriented management information systems. Michael zur Muehlen discusses the integration of workflow audit trail data with existing data warehouse structures and develops a reference architecture for process-oriented management information systems. Starting with an organizational and technical analysis of process organizations, this book provides a comprehensive documentation of business process management, workflow technology, and existing standardization efforts. The proposed reference architecture is validated in an industry context. A prototypical implementation of the reference architecture and its integration with a commercial business process management system are demonstrated as well. This book is directed at both practitioners and academics in the fields of business process management, management accounting, and information systems.http://www.bibsonomy.org/bibtex/2df887d1fbe31f83719f3a6fdfc7cc63d/msnmsn2008-03-31T21:54:40+02:00research.is info.refs.thesis cites.procm research.bizInt.ea cites.goarch state.printed <span style="color:#555555;">Tomi <a href="http://www.bibsonomy.org/author/Pienimäki">Pienim&#228;ki</a> </span><em>Tampere University of Technology, </em>(<em>2005</em>)Mon Mar 31 21:54:40 CEST 2008A Business Application Architecture Framework in Manufacturing Industry2005research.is info.refs.thesis cites.procm research.bizInt.ea cites.goarch state.printed In a contemporary business environment business processes are under constant change. Information systems and applications are becoming more complex so that they are able to support and react promptly to these complicated business requirements. An architecture framework is an instrument for managing a complex information systems environment. This study concentrates on issues related to comprehensive business application architectures in industrial manufacturing companies. The objective of this study is to determine what common factors can be identified in business application architectures in the case companies and how the business application architectures have been developed in the case companies. In order to reach the objective of the study a framework with which the business application architectures and business application architecture development processes could be analyzed and enhanced was first developed. The research approach used was qualitative multiple case research. Business application architectures and business application architecture development processes were studied in four case companies. As a research method mainly the action-oriented research approach was used. In addition, this study has features of constructive research and conceptual research approaches. The results suggest that the business application architecture framework is a powerful instrument in analyzing and enhancing business application architectures and it has influenced the business practices in some companies. The framework consists of the business application classification model and the reference model for the business application architecture development process. The results suggest that it is preferable to aim towards an integrated business application architecture based on average applications rather than invest in best-in-class applications, which are not integrated. The case companies also aimed towards a higher level of integration within their supply chain. In all case companies the development and implementation of the business application architecture took several years. Consequently, the architecture has to be flexible so that it is able to adapt to emerging changes in requirements during the development and implementation of the architecture. Target business application architectures included less applications and less complexity but provided the same functionality as the initial architecture. On the other hand, typically the actual number of different applications typically didn't decrease in the target architecture. This is because the target business application architecture had more functionality and more features to be supported than the initial architecture. As one result of this thesis it was concluded that case companies did not have an information architecture, but according to the IT management of the case companies it would be useful to have.http://www.bibsonomy.org/bibtex/244c565c8a5662b2c494c3aa951c9d4a9/msnmsn2008-03-31T11:26:14+02:00cites.gradu info.refs.books research.ir <span style="color:#555555;">Ricardo <a href="http://www.bibsonomy.org/author/Baeza-Yates">Baeza-Yates</a> and Berthier <a href="http://www.bibsonomy.org/author/Ribeiro-Neto">Ribeiro-Neto</a> </span><em>Addison-Wesley, </em>(<em>1999</em>)Mon Mar 31 11:26:14 CEST 2008Modern Information Retrieval1999cites.gradu info.refs.books research.ir
