I am following the convention that every table's primary key is called 'id', and every table's foreign key is called <referenced-table>_id. This is the convention that I picked up from CakePHP, and probably RoR. This convention was a requirement for the project. So, for example, packages has many files (WHERE packages.id = files.package_id), and files have many lines (WHERE files.id = lines.file_id).
The parent to child part works when using this convention, but that the child to grandchild linking does not.
