IBM DB2: The Past, Present & Future Future & Present Past, The DB2: IBM The launch of DB2 on June 7, 1983, marked the birth of relational database as a cornerstone for the enterprise; 30 years later, DB2 for z/OS is still the undisputed leader in the RDBMS market and the envy of its competitors when it comes to total system availability, scalability, security, reliability, and cost effectiveness. A majority of Fortune 500® companies, including the world’s top banks, retailers, and insurance providers, store mission-critical operational data in IBM® System z® and DB2® for z/OS®. Why? It seems everyone offers a marketing bundle “just like the mainframe,” and while some of these solutions have some basic capabilities, DB2 for z/OS and System z continue to lead the way with fresh capabilities to handle rapidly changing, diverse, and unpredictable workloads while maximizing resource utilization and investment. During 2013, IBM will celebrate the 30th anniversary of DB2 with customers, business partners, users, employees, and DB2 fans all around the world. We announced DB2 11 Early Support Program in October 2012, and we expect General Availability to follow shortly. This book is packed with rich information to help you manage your IT business systems. Don Haderle, the father of DB2, shares with us the history and growth of DB2, and customer testimonials highlight DB2 memories and milestones. Next, John Campbell provides a detailed overview on the planning stage of migrating to IBM DB2 10, and finally Terry Purcell provides a technical overview of the business benefits of IBM DB2 for z/OS Optimizer. We hope you enjoy this new book. Find out why DB2 is still growing after 30 years and how it is helping our customers to reduce costs and grow.
