Using flows in information integration

F. Leymann, D. Roller
2002 IBM Systems Journal  
For an environment provided by a relational database, the SQL/MED (Structured Query Language/Management of External Data) standard 2 defines a special kind of adapter called a wrapper.  ...  When a database system is coupled with a flow engine, all of these capabilities are made available to database applications.  ...  He is the coauthor of a textbook about workflow systems.  ...

Coupling of FDBS and WfMS for Integrating Database and Application Systems: Architecture, Complexity, Performance [chapter]

Klaudia Hergula, Theo Härder
2002 Lecture Notes in Computer Science  
With the emergence of so-called application systems which encapsulate databases and related application components, pure data integration using, for example, a federated database system is not possible  ...  Starting with the overall architecture, we explain the functionality and cooperation of its core components: a federated database system and, connected via a wrapper, a workflow management system composing  ...  In order to be independent of vendor-specific solutions, a standardized wrapper interface according to the draft of SQL/MED (Database Languages -SQL -Part 9: Management of External Data, [6] ) is used  ...

How foreign function integration conquers heterogeneous query processing

Klaudia Hergula, Theo Härder
2001 Proceedings of the tenth international conference on Information and knowledge management - CIKM'01  
With the emergence of application systems which encapsulate databases and related application components, pure data integration using, for example, a federated database system is not possible anymore.  ...  Starting with the overall architecture, we explain the functionality and cooperation of its core components: a federated database system and a workflow management system connected via a wrapper.  ...  Actually, this wrapper consists of two parts: one part is located at the FDBS side serving the SQL/MED interface at the FDBS.  ...

On Bridging Relational and Document-Centric Data Stores [chapter]

John Roijackers, George H. L. Fletcher
2013 Lecture Notes in Computer Science  
The challenges of document management at web scale have stimulated a recent trend towards the development of document-centric "NoSQL" data stores.  ...  Many query tasks naturally involve reasoning over data residing across NoSQL and relational "SQL" databases.  ...  Calders and A. Serebrenik for their feedback. References  ...

Information and Process Integration: A Life Science Perspective

Johann-Christoph Organizers, Freytag, Thure Etzold, Carolegoble, Peter Schwarz, Rolf Apweiler, Rolf Apweiler@ebi, Uk, Carole Goble
unpublished
With the advent of middleware technology, the focus of research and development in data integration has begun to shift.  ...  At the same time the bioinformatics community has developed hundreds of tools to visualize, to analyze, and to process that data, with the goal of turning raw data as produced by sequencing machines into  ...  I close with a description of Clio, a prototype system that addresses the problem if mapping a set of legacy schemas into a known target schema.  ...

A middleware approach for combining heterogeneous data sources - integration of generic query and predefined function access

K. Hergula, T. Harder
Proceedings of the First International Conference on Web Information Systems Engineering  
Starting with the overall architecture, we explain the functionality and cooperation of its core components: a federated database system (FDBS) and a workflow management system (WfMS).  ...  With the emergence of so-called application systems which encapsulate databases and their applications, pure data integration using, for example, a federated database system is not possible anymore.  ...  As the key issue of our approach, we combine the services of a federated database system to provide data integration with the services of a workflow management system to handle platform and communication  ...
