Much of the current attention is focused on the use of P2P computing for exchanging media files. But P2P systems have actually been around for a long time and many application scenarios exist. In this paper we discuss on one hand the evolution of P2P middleware from simple file-sharing to decentralized data storage; on the other hand the impact on the future development of decentralized workflows. Building up a P2P based data storage, with similar properties as a standard data store, opens many research issues. While P2P databases enable distributed data storage, distributed control flows are considered in decentralized workflows. The paper will present several research issues addressing the collaboration and coordination problem in distributed environments without a centralized coordination instance by means of a B2B application scenario. © 2004 Oldenbourg Wissenschaftsverlag GmbH Communications engineering / telecommunications nationallicence Data in computer systems nationallicence Systems management nationallicence Risse Thomas aut Knežević Predrag aut Wombacher Andreas aut it - Information Technology (vormals it+ti)/Methoden und innovative Anwendungen der Informatik und Informationstechnik Oldenbourg Wissenschaftsverlag GmbH 46/4/2004(2004-04-01), 193-199 1611-2776 46:4/2004<193 2004 46 itit https://doi.org/10.1524/itit.46.4.193.36078 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/itit.46.4.193.36078 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Risse Thomas aut NATIONALLICENCE 700 1- Knežević Predrag aut NATIONALLICENCE 700 1- Wombacher Andreas aut NATIONALLICENCE 773 0- it - Information Technology (vormals it+ti)/Methoden und innovative Anwendungen der Informatik und Informationstechnik Oldenbourg Wissenschaftsverlag GmbH 46/4/2004(2004-04-01), 193-199 1611-2776 46:4/2004<193 2004 46 itit CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
