: DB2 8.1 Enterprise Server Edition"> Executive Summary: DB2 8.1 Enterprise Server Edition
Version 8.1s improvements in uptime, manageability and administrative tools will appeal to current DB2 customers, while its Workgroup Server Edition continues to offer strong value, especially for those looking for an enterprise database to run on one- to four-CPU-based servers. This release doesnt change the competitive landscape but fine-tunes DB2 in a number of useful ways.
DB2 provides a middle path between Microsofts SQL Server (less expensive and simpler to manage but not as rich in functionality) and Oracle9i (more expensive to purchase and similar in administrative complexity). DB2s growing consolidation of management tools between the server and mainframe will help to lower costs for shops already using DB2 on IBM zSeries systems. (+) Increases uptime because more configuration changes dont require a restart; adds data compression; new Health Center, Memory Visualizer and Development Center tools aid manageability and speed of development; new type 4 Java Database Connectivity driver; data clustering on more than one search key. (-) Doesnt provide the fine-grained security controls or Enterprise JavaBean support found in Oracle9i and Sybase ASE; XML storage features are not as flexible as those offered by Oracle9i; Web service features require use of IBMs WebSphere application server; data compression restricted to default and null column values.
