Support for modular migrations #11

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
Currently, MDL file allows to specify migration name. This name, however, 
is not used anywhere.

What I propose is to add support for modular migrations, whereby Wizardby 
will record which module (that is, which named migration) is at what 
version.

For instance:

    migration "Core" revision => 1:
        ...

    migration "Plugin" revision => 1:
        ...

These two migrations will then be able to operate pretty much independently 
on one physical database.

A module could then be associated with an SQL schema so all objects in the 
module would be created within the given schema
Like

  migration "CarModule" revision => 1, schema => Cars:
    ...
