Hi Daniel,

It really depends on which database you are using.  SQL database like 
FirebirdSQL and MySQL certainly require client libraries to be distributed, but 
usually just the client libraries.  Most multi-user systems like FirebirdSQL and 
MySQL require that you have a database server setup somewhere on the network.

Some databases like FirebirdSQL offer an "embedded" mode for single user access. 
  In that case you only need to distribute a few files.

Also, SQLite is an easy database to use and doesn't require a database server 
for multi-user use, but does still require the SQLite3 dll/so to be distributed. 
  I don't think it intended for serious multi-user deployments, but if you're 
just needing a local database to use...
