Recommended database driver

[babygal]

I am supposed to implement database in my code/project.
I am new to database and have no idea which database driver to select.
What is the recommended database driver?

It depends on many and many factors:
1. count of data, you will store in database,
2. complexity of your database ( number of links, etc. ),
2. if there will be only one local connection to database file or it will be many connections via network,
3. do you want your app to be crossplatform
4. ... and many others

for the first time I can recommend SQLITE (http://sqlite.org/docs.html) database
