Since the information managed is critical,\n   security constraints have to be correctly established in order to avoid\n   unauthorized access. In previous work we defined a Model-Driven based\n   approach for developing a secure DW repository by following a relational\n   approach. Nevertheless, it is also important to define security constraints\n   in the metadata layer that connects the DW repository with the OLAP tools;\n   that is, over the same multidimensional structures that end users manage.\n   This paper incorporates a proposal for developing secure OLAP applications\n   within our previous approach: it improves a UML profile for conceptual\n   modelling; it defines a logical metamodel for OLAP applications; and it\n   defines and implements transformations from conceptual to logical models, as\n   well as from logical models to secure implementation in a specific OLAP tool\n   (SQL Server Analysis Services).<\/jats:p>","DOI":"10.2298\/csis140617007b","type":"journal-article","created":{"date-parts":[[2015,4,17]],"date-time":"2015-04-17T13:31:39Z","timestamp":1429277499000},"page":"541-565","source":"Crossref","is-referenced-by-count":4,"title":["An MDA approach for developing secure OLAP applications: Metamodels and transformations"],"prefix":"10.2298","volume":"12","author":[{"given":"Carlos","family":"Blanco","sequence":"first","affiliation":[{"name":"GSyA and ISTR Research Groups, Dep. of Computer Science and Electronics, Faculty of Sciences, Univeristy of Cantabria, Santander, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Ignacio","given":"Guzm\u00e1n","family":"de","sequence":"additional","affiliation":[{"name":"Alarcos Research Group.
