In order to increase the volume of underlying patient data DWs at different institutions can be connected to research networks. Two obstacles to connect a DW to such a network are the syntactical differences between the involved DW technologies and differences in the data models of the connected DWs. The current work presents an approach to tackle both problems by translating queries from the DW system openEHR into queries from the DW system i2b2 and vice versa. For the subset of queries expressible in the query languages of both systems, the presented approach is well feasible.<\/jats:p>","DOI":"10.3233\/978-1-61499-959-1-16","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T17:29:25Z","timestamp":1740158965000},"source":"Crossref","is-referenced-by-count":0,"title":["Query Translation Between openEHR and i2b2"],"prefix":"10.3233","author":[{"family":"Fette Georg","sequence":"additional","affiliation":[]},{"family":"Kaspar Mathias","sequence":"additional","affiliation":[]},{"family":"Liman Leon","sequence":"additional","affiliation":[]},{"family":"Dietrich Georg","sequence":"additional","affiliation":[]},{"family":"Ertl Maximilian","sequence":"additional","affiliation":[]},{"family":"Krebs Jonathan","sequence":"additional","affiliation":[]},{"family":"St&ouml;rk Stefan","sequence":"additional","affiliation":[]},{"family":"Puppe Frank","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","ICT for Health Science Research"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T18:10:17Z","timestamp":1740161417000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-958-4&spage=16&doi=10.3233\/978-1-61499-959-1-16"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-959-1-16","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2019]]}}}
