Embedded Databases

A while ago, we were evaluating building a product that would run on a users desktop (fat client in the old school terminology, winform in this era :-) ), one of the requirements was that it would need to store data. An embedded database would be a great fit, preferably a relational one.

MSDE (or now that that SQL2005 shipped) Sql Server Express just wouldn't cust the mustard. It's not a question of capacity, speed or memory footprint (although memory footprint could be an issue), it is just an issue of size. How can you justify that for a software that is 1,2 or 3 Mb, you multiply that size by 10 or 20 times, just to include a database? (an issue a user, specially a non technical user doesn't care about).

Since this would be a low cost product, with a very small niche market all pennies would count, so the preference was a on either a low cost (or preferably) free solution.

At the time, this was our short list.

SqlLite - At the time i've looked if someone had ported it to managed code using Managed C++. No dice here, but there is an ADO.NET Provider.  Which should be enough. SqlLite seems both small and fast, and has a solid reputation.

Firebird - A product with a solid reputation, and that seems to have a good and loyal user base. It 's not managed,but like SqlLite it also has managed ADO.NET providers. It has a good reputation, it seems to have a small footprint, and it looks like a very easy product to use as and embedded data store.

VistaDB - Also seemed like a nice product, but it costs $$$. Which somehow it puts it on a lower level than the SqlLite and Firebird (due to our constraints).

Since the project was postponed, i haven't evaluated the solution on it's technical merits. Both SqlLite and Firebird had points on it's favor (cheaper :-D ),and my investigations of VistaDB were very light. (to be read, just read the brochures :-)). Firebird had another point in it's favor. It is supported by LLBLGen Pro, a product that we like, better yet a product which we have already licensed.

Are you still with me? (doubt it), basically i've written all this crap, because i'm a sucker for goodies, i usually pass on the opportunity for useless freebies, but this free may eventually be useful to me. :-)

Vista Software, seems to be engaging in some kind of viral marketing campaign, it is offering free licenses to bloggers who include the following marketing babble:

VistaDB 2.1 database for .NET has been released

Since i'm an aforementioned freebie sucker, i'm applying for my free license. However i had to write something with (at least in appearence) useful, so i'm not labeled as a marketing whore. :-)

In my defense, i already wrote a post in this topic (with some imagination) of embedded databases here.
