I'm a fan of U2 - MV in general even. But in this case I have to agree with Rob: We really need to quantify what it means to "win" otherwise the words do little more than tickle an emotional response.
Having had some time with several MV systems as well as several SQL systems, there are areas of each that in a head-to-head comparison, one would "win" over the other based on price, performance, flexibility, scalability, and reliability. And it's not always U2/MV and it's not always SQL. For getting right to work without extensive tuning, I'd say U2 holds the upper hand. In terms of indexing and application of multiple indexes to queries, I'd put PostgreSQL over MySQL and both over U2. For clustering, Oracle. For the GUI, SQL Server. For that matter, I'd rank the flexibility of triggers in Unidata over triggers in Universe, and they're both MV. So it's a complex task to assign a "winner" carte blanche without looking deeply into the eyes of specific areas of the products and their applicability to specific problems to be solved. My personal opinion is that there are benefits to all of it. So in that way picking a "winner" really doesn't do much more than polarize. I know if I were creating an application from scratch today, the criteria I might use to make the decision would be different from anyone else making the same decision even if it were the same application. There is "better" and there is "worse" but all of it must be considered in the larger context of the problem to be solved to mean anything at all. -K _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
