When working with several people on a large project that is bound to a database. If you there and back the databases have different levels of development.
You can keep in sync with SQL statements, but these are then incompatible with other database systems.
It also should give the posibility to generate the same db schema on several databases without changing some sql scripts.
new(...) returns an object of type
This is the class's constructor.
This method takes a set of parameters. Only the dbh parameter is mandatory.
