Need info about databse in qt4

HI...
I just installed qt creator 1.2.1 ( based on qt 4.5.3) on windows xp.
I am going to develope a app which uses sqlite database.
I read qt have a driver called qsqlite to access sqlite database.
My question is
Is qt has in-built sqlite database. or i need to install sqlite database separately in my windows system?

sqlite sql-driver is installed by default. you can check all sql-drivers which have been installed using QSqlDatabase::drivers.
