Should I try to use it?
I have nothing against this base, because I have not used it. But, in my projects I WILL NOT use it - the project is fresh, it is not known what bugs and limitations it will reveal (sharpened for Net-, Win-platform?!), Under which license will be distributed (their server is not currently running) ).
How to indulge, test it is quite possible. In real projects, instead of it, I recommend using SQLite of a similar “philosophy” - all the same, support for the SQL language is always relevant. Finally, read the article " Relational databases are doomed? "
