Описание
On-line analytical processing (OLAP) is clearly a new approach to information system technology--offering a much-needed way to make informed decisions better and faster. One of its most important characteristics is multidimensional analysis--analysis that goes beyond the conventional two-dimensional analysis and provides users with rapid retrieval of data from organizational databases, data warehouses, or both. Not only that, but most importantly, says Dr. Thierauf, it allows users to look at different dimensions of the same data, thus enabling them to do analyses across departmental and even corporate boundaries. How it works and OLAP's many benefits to aid users in the public and private sectors is spelled out here, comprehensively yet concisely, and with the author's customary well-developed examples and clear prose. His book will be important reading for people at all levels of management and in all types of organizations.
