**Notice:** this question general, It does not matter what is the programming language. but my inquire about `c++ Qt`, `c#` languages.

I want programming an `windows application` that uses `database system`.  

But I want choose a database system does not require install a database server on a client computer. Just I want the client install the application, then he can use the application after installation and does not require install a database server.

I don't know what is the database appropriate to me ?  

`mySql` , `msSql`, `sqlite`, `etc`.
