The Programmer's Hierarchical Interactive Graphics System (PHIGS) is a computer-graphics standard defining an interface between an application program and a computer-graphics system. PHIGS has been actively under development since 1980. Much of this development has been performed by Technical Committee X3H3 under the American National Standard Institute (ANSI) procedures. PHIGS is also an international standard sponsored by the United States and developed by the international computer-graphics committee, ISO TC97/SC21/WG2. In addition, PHIGS has been selected as the graphics extension to the X-window standard and as part of the Intel i860 P.A.X. standard. The PHIGS standard has received wide acceptance throughout the computer graphics industry. PHIGS libraries are available on most of the high performance three-dimensional graphics platforms. These include IBM, DEC, HP, Sun, Alliant, Stardent, and Silicon Graphics. Despite this acceptance, there are few texts that provide the software engineer with an overview of the standard. The only currently available PHIGS references are in the form of the ANSI functional description, technical papers, and device-specific PHIGS to the novice PHIGS programmer.
William Giovinazzo gives experienced database professionals practical guidance for every aspect of planning and deploying Web-based data warehouses -- and leveraging them for competitive advantage. Unlike previous books, The Web-Enabled Data Warehouse covers all the enabling technologies and analysis approaches you need to know about -- from XML to CRM, Java to customer profiling. Giovinazzo begins by introducing the compelling advantages of integrating business intelligence and data warehouses with Web technology. He reviews the business and technical contexts in which the Web-enabled data warehouse will operate; shows how to build and optimize data warehouse infrastructure, and presents in-depth coverage of key enabling technologies -- including Java, XML and XSL, LDAP directories, and WAP wireless development environments. In the book's final section, Giovinazzo introduces and explains powerful new analysis techniques that can dramatically improve your understanding of customers -- and shows how to integrate data warehouses with CRM and other enterprise systems so you can act on your knowledge far more quickly and efficiently. For every experienced database professional seeking to understand or deploy Web-based data warehouses.
