    Hello All,
    I am developing a multi side aplication that need to read/write to a database at the same time.
    With sqlite, I keep geting a database locked error, even with the pragma set to WAL.

    Is there a DB engine that is both free and that allow concurrent connections ?

    MYSQL and MariaDB that may be are not free for commercial use
    PostgreSQL - i do not know the licencing
    and my personal favorite SQL Server Express. i like express it is free for commercial use and very powerful database.
