The 10-year journey of DM Review has followed the evolution of the management of data from mainframe databases to the Corporate Information Factory where data is distributed to all decision-makers within the enterprise. We have witnessed change at Internet speed and have replaced green bar reports with advanced business intelligence products. We have seen the Internet move from a static Web-page environment to a highly dynamic environment supported by databases that can also be accessed by wireless devices. We have seen businesses change from being product-driven to customer-driven. Those of you who have been in the industry for less than 10 years have experienced more technological change in this cycle than your counterparts experienced in the previous 40 years. This article reflects on the changing technology landscape as covered in the pages of DM Review. I hope you'll enjoy this journey depicting the technological progress we've made since the debut of DM Review in February of 1991.
In 1991, enterprises were focused on the impacts of client/server in relation to mainframe systems. The selection of the right DBMS to support client/server and network versus relational issues were of paramount importance. CASE, expert systems, SAA and the AD/cycle were in vogue as was process modeling. In addition, we were also developing the repository-based data dictionary. Most DBAs were focused on the wholesale movement of applications and data from the mainframe environment to client/server. In addition, the role of the DBA was expanded. DBAs became leaders of data management teams that were responsible for providing accurate, reliable and shareable data. Disaster recovery and restores were hot issues with regard to client/server databases. In reality, all of the major database management issues that we had solved in the mainframe environment were now being reintroduced in the client/server environment.
