The process of transforming a query from the \ndatabase relations to the resources is often referred to as query folding or answering queries \nusing views, where the views are the resources. We present a uniform approach that includes \nas special cases much of the previous work on this subject. Our approach is logic-based \nusing resolution. We deal with integrity constraints, negation, and recursion also within this \nframework.<\/jats:p>","DOI":"10.1017\/s1471068401001375","type":"journal-article","created":{"date-parts":[[2006,6,2]],"date-time":"2006-06-02T09:38:29Z","timestamp":1149241109000},"page":"323-368","source":"Crossref","is-referenced-by-count":20,"title":["A logic-based approach to data integration"],"prefix":"10.1017","volume":"2","author":[{"given":"JOHN","family":"GRANT","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"JACK","family":"MINKER","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2002,4,23]]},"container-title":["Theory and Practice of Logic Programming"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1471068401001375","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,20]],"date-time":"2025-06-20T23:02:30Z","timestamp":1750460550000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1471068401001375\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2002,4,23]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2002,7]]}},"alternative-id":["S1471068401001375"],"URL":"https:\/\/doi.org\/10.1017\/s1471068401001375","relation":{},"ISSN":["1471-0684","1475-3081"],"issn-type":[{"value":"1471-0684","type":"print"},{"value":"1475-3081","type":"electronic"}],"subject":[],"published":{"date-parts":[[2002,4,23]]}}}
