Do you really believe that IMS with all it's overhead has a future in the diminishing mainframe market. As far as I am concerned, IBM tries to hook you into a "technology" and then they just up the price and IMS is a typical example of this. Have you ever tried various TP monitors and compared the cost involved to run them ? I don't think so... even better then that ...

IMS prices have been falling because of subcapacity licensing (WLM), "technology dividend" effects, and renewed tool/utility competition (for the IMS accessories). Mainframe CPU replacement tends to decrease IMS prices (technology dividends and consolidation), not increase them. So I'm truly puzzled by this quote. (Currency effects I might understand, but those won't provide long running trends.) Actually, the real reason IMS revenues trend upward is because of transaction growth that's significantly outpacing the price reductions. The Internet is great for IMS, to put it simply. I should also point out that IMS is ideally suited to the world of XML which, if one looks around for half a second, is on the rise. XML is hierarchical, not relational, and if you understand XML principles you basically understand IMS DB principles. The world needs both forms of data storage. It's frankly silly to claim otherwise, with all due respect to Gartner. Relational databases are fantastic and help solve a broad range of business problems, but they aren't everything. IMS is both a transaction manager and a database. There was no mention in the article of IMS TM. You can write your IMS TM programs in just about any language you like (including Java), and last I checked Java is taught just about everywhere. If there is a shortage of IMS skills, I'd be interested in seeing a salary survey that backs up that assertion. Lastly, IMS is extremely efficient. That's very important for high volume applications, and the world requires more high volume applications each year, not less. My personal opinion(s). - - - - - Timothy F.
