Big data are relevant not only in the academic context, but also in the industrial context, where they play the major role. Indeed, several kinds of application are now exploiting big data, such as: Web advertisement, social network intelligence, e-science applications, smart city applications, and so forth. Among big data, <em>big multidimensional data<\/em> are a special case of big data that fully expose the \u201cfamous\u201d 3V (volume, velocity, variety) and are of relevant interest at now. Within this research context, the seminar \u201c<strong><em>Big OLAP Data Cube Compression Algorithms in Column-Oriented Cloud\/Edge Data Infrastructures<\/em><\/strong>\u201d focuses the attention on the issue of compressing so-called <em>big OLAP data cubes<\/em> over column-oriented cloud\/edge data infrastructures. More specifically, the seminar proposes a specialized representation of massive OLAP data cubes over cloud\/edge environments via column-oriented paradigms, which have been traditionally used in fortunate <em>in-memory database query engines<\/em>. Under this decomposition mechanism, each \u201ccolumn\u201d is then compressed via a state-of-the-art synopsis data structure, called <em>D-Syn<\/em>, which already proofed its effectiveness and efficiency in multidimensional data compression, thanks to an innovative <em>analytical interpretation<\/em> of multidimensional data cubes. The seminar also discusses several alternatives according to which the deriving <em>synopsis chunks<\/em> can be effectively and efficiently distributed across Cloud and\/or Edge nodes, and how to support <em>approximate query answering<\/em> over such big data structures.<\/p>\n<h3>Speaker<\/h3>\n<p><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\" wp-image-7248 alignleft\" src=\"https:\/\/carleton.ca\/cuids\/wp-content\/uploads\/AlfredoCuzocrea.png\" alt=\"\" width=\"248\" height=\"265\" \/><\/p>\n<p>Speaker: <strong>Prof. Alfredo Cuzzocrea<\/strong><\/p>\n<ul>\n<li>iDEA Lab, Director<\/li>\n<li>University of Calabria, Rende, Italy<\/li>\n<li>Excellence Chair in Big Data Management and Analytics, University of Paris City, Paris, France<\/li>\n<li>Honorary Professor of Computer Engineering Amity University, Noida, India<\/li>\n<li>Research Associate, National Research Council (CNR), Rome, Italy<\/li>\n<\/ul>\n<p>Alfredo Cuzzocrea is Professor in Computer Engineering at the University of Calabria, Rende, Italy.
