Wed, 10 Mar 2004 00:00:00 EST

Product information is one of the few remaining strategic information assets within an enterprise that does not have a dedicated system of record. This is not surprising when one considers the complexities of product information management (PIM). Specifically, a comprehensive product information management application must be able to handle structured and unstructured information, share data, accommodate a variety of constantly changing data models, manage multiple inter-relationships, and enable multiple hierarchies, all without duplication of data.

Integration Is the Killer App

Thu, 27 Feb 2003 00:00:00 EST

In 1975 Niklaus Wirth, the Swiss computer scientist who created the Pascal programming language, published a seminal book entitled Algorithms + Data Structures = Programs. If Wirth had written about business applications, Computing + Storage = Applications would have been a better title. Of course, in 1975 there weren't that many business applications. Most of them ran limited back-office functions on mainframes. PCs weren't on the map. The killer app for PCs - the first spreadsheet - wouldn't be created until 1981.
