Hi Long, > Thank you very much for the response. > I have some more question on Valentina: > 1) Is there a security on single user machine?
Do you mean in specific encryption? You can encrypt entire databases or down to the record/field level. > 2) Is server secured and just as fast? Speed is one of the features that differentiates Valentina - we have some comparisions on our website. We did an analysis last year vs MS SQL Server and found that we were at least x2 + (and often much, much higher) in almost every operation. > 3) How does synchronization between client/server? Ruslan can better explain how this works. Clearly this is something you do want to manage in your code. > 4) How much do you pay for support? What Trausti has been talking about so far is what we do on our mailing list, which is free. The Valentina mailing list has a very strong group of db professionals so it's a great place to ask questions. We have developers working all the time so if there is a small problem we can usually sort it out fairly quickly. We have "pay" support plans as well and we can also come up with one that suits each customer. For example, when Nikon Corporation shipped their digital cameras with a Valentina powered application they wanted a special support plan so that they can reach an engineer at any time. > 5) What other features offered that Postgres doesn't have. Others will have to chime in here since I'm not that familiar with Postgre. I think there are a lot of "clients" available for PostGre but I suspect that given its roots they are all of different quality and implementation, ie if you want to deal with PostGre from a .net based application vs COM vs Director vs REALbasic vs Revolution vs PHP vs Cocoa.... - since Valentina solutions are available for all these platforms and its VERY rare that our customer use only one tool, we've done our best to make sure interacting with the database is consistent enough that its possible to build new solutions around a Valentina core with a minimum amount of trouble.
