IBM pushes DRDA link to relational data; DRDA is key to Information Warehouse framework, but skeptics claim the architecture is proprietary - Distributed Relational Database Architecture - SAA: Data Management Update

Software Magazine, Nov 15, 1991 by Mary Alice Hanna

DBS promises the first phase of its client/server software system will begin shipping in early 1992.

Sam Greenblatt, director of Architecture, Design and Planning at Candle Corp., Los Angeles, contends that the use of client/server technology will not hinder performance.

"The performance of DB2 is directly proportional to how you set up the query," Greenblatt said. "If the query is set up properly, using object-oriented tools. I assume that it will be highly efficient."

Greenblatt also contended that undislosed new technology will address any performance problems. The workability of the Information Warehouse will be tied directly to the strength of the products marketed under its aegis, Greenblatt said.

The technological response of many independent software vendors to the Information Warehouse remains under wraps, observers note.

Whatever path IW takes, most expect it will undoubtedly boost compatibility between the software of different vendors.

Knowles of Sybase said, "I don't see DRDA becoming a replacement for every other protocol. Most customers will have a mixture of database, networks and protocols. They will insist on the most robust protocol."

IBM, by proposing architectures and frameworks, has been helpful in defining the probable directions for the computer and software industry, many observers agree.

For example, Andrew Filipowski, CEO and founder of Platinum Technology Inc., Lombard, Ill., said, "I am very glad that IBM is taking care of the long-range plans for the industry. The occasional screams from customers that nothing is ready is just to make sure that the new technology will be ready when they are." Platinum is a charter member of the International Alliance for System View.

"Although very few resources are left in most shops to be able to deal with the new technology, the majority of IS shops are very pleased with the new directions in data management," Filipowski said.
