The standard language for the data warehouse metadata representation is the Common Warehouse Metamodel. However, business intelligence systems include also approximate query answering systems, since these software tools provide fast responses for decision making on the basis of approximate query processing. Currently, the standard meta-model does not allow to represent the metadata needed by approximate query answering systems. In this paper, we propose an extension of the standard metamodel, in order to define the metadata to be used in online approximate analytical processing. These metadata have been successfully adopted in ADAP, a web-based approximate query answering system that creates and uses statistical data profiles.<\/jats:p>","DOI":"10.1155\/2012\/247592","type":"journal-article","created":{"date-parts":[[2012,9,3]],"date-time":"2012-09-03T21:00:55Z","timestamp":1346706055000},"page":"1-13","source":"Crossref","is-referenced-by-count":1,"title":["Metadata for Approximate Query Answering Systems"],"prefix":"10.1155","volume":"2012","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6957-2993","authenticated-orcid":true,"given":"Francesco","family":"Di Tria","sequence":"first","affiliation":[{"name":"Dipartimento di Informatica, Universit\u00e0 degli Studi di Bari Aldo Moro, Via Orabona 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ezio","family":"Lefons","sequence":"additional","affiliation":[{"name":"Dipartimento di Informatica, Universit\u00e0 degli Studi di Bari Aldo Moro, Via Orabona 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Filippo","family":"Tangorra","sequence":"additional","affiliation":[{"name":"Dipartimento di Informatica, Universit\u00e0 degli Studi di Bari Aldo Moro, Via Orabona 4, 70125 Bari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"year":"2002","key":"1"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-9236(02)00208-7"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/2.970575"},{"issue":"2-3","key":"9","first-page":"199","volume":"10","year":"2001","journal-title":"The International Journal on Very Large Data Bases"},{"issue":"1","key":"12","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/0306-4379(95)00001-K","volume":"20","year":"1995","journal-title":"Information Systems"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1145\/1508857.1508860"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1145\/1412331.1412335"},{"volume-title":"Data reduction for data analysis","year":"2008","key":"17"},{"issue":"4","key":"18","doi-asserted-by":"crossref","first-page":"360","DOI":"10.1016\/j.infsof.2011.11.004","volume":"54","year":"2012","journal-title":"Information and Software Technology"},{"year":"2000","key":"20"},{"year":"2002","key":"21"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1109\/2.76261"},{"year":"2007","key":"23"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1016\/j.datak.2007.05.003"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1007\/s10796-007-9032-9"}],"container-title":["Advances in Software Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/247592.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/247592.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/archive\/2012\/247592.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T03:42:34Z","timestamp":1607571754000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/ase\/2012\/247592\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,9,3]]},"references-count":15,"alternative-id":["247592","247592"],"URL":"https:\/\/doi.org\/10.1155\/2012\/247592","relation":{},"ISSN":["1687-8655","1687-8663"],"issn-type":[{"type":"print","value":"1687-8655"},{"type":"electronic","value":"1687-8663"}],"subject":[],"published":{"date-parts":[[2012,9,3]]}}}
