Re: [U2] Maverick DBMS
Hi Ross, Have you mentioned the fact that you can now run QM on a PDA on this forum? May be a few problems in this group that this solution could be applied to :-) No but thanks for doing it!!! And, Robert, I stand corrected on my (mis)understanding of the status of Maverick.

Re: [U2] Maverick DBMS
Hi Mac, Apologies if this is partially a product advert but you did ask the question As far as I know, Maverick has quietly died. I may be completely wrong. Even though we have an open source version of our own OpenQM product, I would not recommend use of open source for a commercial development as it has no warranty or support. You could be dead in the water for a considerable time while trying to fix problems. This seems to be a difficult approach to sell to management. Open source is fine for those who want to develop some nifty new feature that the product developers would never have thought of but for a fully supported business system you really need a commercial licence. Also, as is beginning to happen in OpenQM and probably applies to other products too, the more advanced features may not be in the open source. From listening to users who have gone the open source route, I think that they often end up spending more getting the system up and running than they would have spent for a commercial licence. I am evaluating it as an alternative to Universe, specifically looking at converting our BASIC code to Java. Is this possible ? Why would you want to do this? The very nature of both multivalue Basic and Java suggests that this will cost you heavily in performance. If there are things that you want to do that can only be done in Java, it should be possible to escape from Basic out into Java or the reverse.

RE: [U2] Maverick DBMS
I looked at Maverick along time ago. Yes it was written in Java but unless my memory is totatly gone the datastore was one of the open-source databases (MySQL ??). I just could not grasp how his was a help - now you have not only Java to worry about you have another database to hold your pick data. Martin is correct in my opinion - one spends too much time in getting the database to compile, to run etc - and you can not concentrate on programming. If you have a commercial use a commercial database. I am sure you are aware you can use Java with U2 products - get the best of both words. Don't know about Martin's but I would bet he has a Java interface also. I have friends that us QM and they love it. good luck grs -Original Message- From: [EMAIL PROTECTED] [mailto:owner-u2- [EMAIL PROTECTED] On Behalf Of Mac Bhyat Sent: Tuesday, March 20, 2007 1:24 AM To: u2-users@listserver.u2ug.org Subject: [U2] Maverick DBMS Hi, Has anyone had any experience with the open source mv database maverick.

Re: [U2] Maverick DBMS
Mac, If the goal is to Java program with mv data, you don't need to leave UniVerse. There are documented Java-accessible UniVerse connectors where you can keep the data in UniVerse and still do the bulk of the coding in Java. Look at UOJ (UniVerse Objects For Java) for a start. - Chuck Java-Jolted Barouch Mac Bhyat wrote: I am evaluating it as an alternative to Universe, specifically looking at converting our BASIC code to Java.

Is this possible ?, or does maverick just put a wrapper around by BASIC code so that it acts like a Java Class The maverick basic compiler compiles basic into either java source code or directly into java byte code(a class file). Today compiling directly to bytecode is preferred method, the java source code generator hasnt been as well maintained lately(my fault). The resulting classfiles run in a JVM the same as any classfile compiled from java source. They are freely callable to and from java routines. Also the large body of third party java libraries can be easily integrated with the basic code. This is a list for u2 users, probably better to ask further questions on the maverick-devel mailing list. - Robert --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

I just could not grasp how his was a help - now you have not only Java to worry about you have another database to hold your pick data. Without writing out a treatise, the idea was prevent your data from being trapped within an obscure data format. Managers hate that, they know it implies paying ever increasing maintenance on the DB itself and greater and greater difficulty and thus expense finding staff competent in managing it. - Robert --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

Have been a bit slack adding new code lately but i am still breathing at this moment! Why would you want to do this? The very nature of both multivalue Basic and Java suggests that this will cost you heavily in performance. Just for reference have worked really hard on the basic programs runtime library to get the performance close to the commercial mv variants. From actually doing it there is really *no* significant penalty in executing your basic code in a JVM(which is JIT compiled) relative to the homespun VM's in other mv platforms or the C translated code jbase produces. The problems have all being due to the library implementation(ie wrong algorithm chosen) not the actual underlying platform. For example last week the debate over using -1 vs X++ type addressing runs pretty much the same under maverick, you can use either without penalty. - Robert --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
RE: [U2] Maverick DBMS
Martin, I believe MaVerick is still alive kicking (Robert Colquhoun has just released a stack of fixes/changes in the past week) Also, reading between the lines of the OP, I think the interest was more in terms of converting Basic Code to Java, rather than necessarily looking for a DBMS replacement (could be totally wrong - that would mean twice in the last 5 minutes :-) Have you mentioned the fact that you can now run QM on a PDA on this forum?
