I currently use SQLite for some applications that need a light embedded database. These apps use multiple processes that access the same database. For concurrent write access this is cumbersome. We have done some work-arounds to overcome this to some degree, but clearly SQLite has it limits.
So, we looked around and found an interesting, but very unknown, database: Scimore. It's quite capable; it's embedded version uses an out-of-process technique that allows multi-concurrency read and write access. Besides this, it's free. It's almost too good to be true.
From our first test results it seems to be very good and fast, but then why is it so unknown?
Therefore my question: Do you know this database; if so what are your experiences regarding reliability?
NB: I'm only asking for real usage experiences; not opinions.
