IBM's Database 2 (DB2) relational database management system (RDBMS) shipped in the early 1980s and drove billions of dollars of revenue to IBM and other firms within its first decade. The product ...spawned a wealth of add-on tools, shaped the future of mainframe computing, and provided independent software vendors with a strong, reliable, and scalable platform for mission-critical applications. Today, DB2 spans multiple operating systems and is widely deployed across a broad spectrum of industries. This article explores the beginnings of DB2 and traces its rise to prominence.
Information technology architects increasingly find themselves searching for better ways to access, integrate, and leverage their information, applications, and business processes. Information ...integration, in particular, is critical to the community of Web-based businesses, as firms that are able to leverage their information resources most effectively are best positioned to emerge as leaders in their industries. In this paper, we explore how companies can solve this complex business challenge by extending the reach of WebSphere technology with DB2 Information Integrator (II). DB2 II offers WebSphere developers a new approach to coping with diverse and distributed information sources, enabling them to reduce programming costs, shorten development cycles, and attain reasonable levels of performance for server-side components that need to integrate information throughout their enterprises and partner networks.PUBLICATION ABSTRACT
An accurate assessment of muscle size and tissue density can be obtained by X-ray computed tomography. CAT scans of the extensor and flexor muscle compartments of the leg and forearm were performed ...on normal subjects to establish: normal ranges of muscle densities, and the effect of sex and side dominance on muscle size and density. The same muscle groups were studied in patients with nerve damage resulting in either total or very extensive denervation of the corresponding muscle compartments. In normal subjects muscle density is significantly lower in females and the effect of side dominance is more marked in the upper extremity. Denervated muscle compartments show reduced cross-section and density. Electrotherapy does not appear to be effective in preventing muscle atrophy.
