Good embedded database for Qt?
Besides SQLite, any of the following will work with Qt as an embedded database. Qt already has drivers for most of them, and you can find drivers for others. In terms of merging data "with other sites", it all depends on what you mean by this. Replication solutions for SQLite and MySQL Embedded may not be great (or exist at all). I would probably go with Firebird or Berkley.
