What I particularly liked about it when using it in conjunction with REALbasic (which can be great for low budget applications), was its object-relational nature, binary links (habtm without a real table) and its random virtual recordset access. Instead of having to use LIMIT and OFFSET, you could query a recordset that let’s say yields a 50,000 record result, then randomly say: well, get me object 10,212 to 10,500 and 35,141 and 44,984 to 45,014 and send it over to me. There’s a whole lot of query parsing and seperate queries involved if you’d be using plain sql for this. I don’t know how far this support is backed into their adapter, but if it is, you’ll be pleasantly surprised. To give you a simple example, in a company I used to work for, a prospect asked us to make his very large database with quite a few linked tables live searchable locally on those old clamshell ibooks and some superslow dell laptops. I spent about one day, maybe even a little less and I had both the Windows and Mac version of the app compiled and ready to run, including an import procedure to import all the data. Every keydown in the app narrowed the list down almost instantly using a random access datagrid, and I’m talking about some fulltext searched fields here too or you could browse through all of the records using the scrollbar. We never deemed such a thing possible on those old machines, still Valentina did it without a fuss. Also, if you look at the licensing scheme, it’s a lot more clear than MySQL’s, which is not as free as you claim it to be. Best regards Peter De Berdt ---

What does “not as free” even mean? You’re very confused. If the degree of “free” MySQL offers isn’t enough then there’s also PostgreSQL and SQLite as I mentioned before. And who really cares if MySQL is free or not, they’re not spamming off-topic ads into the list. – Greg D. [http://destiney.com/](http://destiney.com/) ---

It means if you make money of something that uses mysql, you have to pay for it (and you have to pay a lot). Although some might say if the customer installs mysql themselves, the commercial license doesn’t apply, nor if your application can use different databases, nor if the mysql database adapter is open source. Everybody has a different story about what is the truth now. Unless you’re using the 4.0 version of mysql that is, which was basically free IIRC. That’s what I call a confusing and “not as free as you claim” license. > You’re very confused.

Valentina still has several features that make it stand out over all the databases you mentioned (and may have shortcomings compared to them). > And who really cares if MySQL is free or not, they’re not spamming > off-topic ads into the list. One message about a new rails database adapter for a commercial database is something you consider spamming? Why didn’t you go all berserk on the Openbase adapter announcement then. Guess Lynn should have made the message longer and with lots of asterisks and [ANN] headers, maybe that would have been less spam to you. If the Lynn starts flooding this list on a daily basis with that announcement just like the 2GB free download space (or what is it) bullocks or non-ruby or RoR related (check the website, it’s about Rails, and it’s posted on a Rails mailing list), then I’ll be happy to support your case. But I understand your frustration with spam these days, this pre-holiday period has been a real pain for my mailbox too =) Best regards Peter De Berdt ---

That is entirely dependent on total cost of your project and if those products do everything everyone needs - it has almost nothing to do with it being free to download. Unless developer time is totally free, and the impact of delivery is non-existent, then no worries. ---

No actually… Valentina is not tuned for any OR frameworks. Because we never have put such target. Actually we only now starting to check this OR frameworks world (ROR, Hibernate). We never did this because Valentina is not RDBMS, it is Object-Relational. So we have consider any OR MAPs to be not needed. But it seems that if do OR framework around ORDBMS it will be more clean/thing/ simple than one around RDBMS. Its nature of engine and format of db files really give many enough benefits for OR frameworks. For example, Valentina has RecID and OID fields in tables which eat ZERO disk space, while still do job. Also Valentina is vertical format database (not traditional row-format). Also Valentina has on low level the Link abstraction, which you will not find in any other RDBMS. And so on. [http://www.valentina-db.com/dokuwiki/doku.php?id=paradigma:public:en:documen](http://www.valentina-db.com/dokuwiki/doku.php?id=paradigma:public:en:documen) tation:vkernel:vlink:vlink Besides, that developer have not implement yet any Valentina-specific optimizations. For example we push him to start use Links, RecId, OID, SQL with bindings, and so on. We are sure that when he optimize framework with this features, he will get easy 2-10 times speed up overall. And I want underline again, Valentina was NOT born to be used with OR-frameworks. 99% of Valentina developers use it just as ORDBMS without any frameworks. And from this 99% may be 50% use it as pure RDBMS not touching OR-features. > > Valentina developers usually are developers who are NOT satisfied with all > > these mentioned dbs.

Aha, so problem is in your “religion”. Then sorry, sorry… Keep going with your gods :-))) Nobody going touch personally you. But note, that we was FORSED by many requests from Valentina users to enable Valentina database for ROR. So please, Greg, try understand that EXCEPT you exists other developers, which _may_ have other opinion and point of view about db tools and needs of _their_ clients. Welcome to multi-opinion multi-color multi-polar world 🙂 > I don’t really know why you want to stay on this speed tangent when > the real issue here is spamming the list with an off-topic ad for a > closed source project. Does this list have the name like “open-source-software-only” ? But no. Its about ROR and ANYTHING related to ROR. Am I right Greg? Can you assume that after this “ad for a closed source project”, some members of this list will get FREE INFORMATION about tool which allow them better solve their tasks? Why you want prevent them from this??? You are censor? You like mySQL? But we know a lots of developers, which hate it. By the way, your first message into this thread was about price of Valentina vs mySQL. I have forget to mention that we have for Linux web developers totally FREE Valentina Community Server. > Get over yourself and your “fast” database and let people discover the project > through Google like normal. I’m sure there are billions of developers > searching for a “faster than anything out there” database right this minute. 1. exists law/rule about this way only? Point by finger please. if you cannot point such law please do not teach others. 2. Hmm, You like and use Google??? Am I right they use own _closed-source_ software for search engines? So be consistent, and “trash” it from your tools. :-)) Also I believe you _never_ use such things as Windows, MAC OS X, Dreamweaver, Flash, Photoshop, inDesign, ShockWave, Director, Opera, and thousands of other cool titles?
