When beginning a green-field project, a broad, 10,000 ft overview of the data models in your application. Not only in SQL, but also in terms of config files, easy to edit data files for static data, large files, small numerous files, etc etc. Having the right data model can mean a world of difference as to how flexible your application can be. Also, decoupling between data models. For example, decoupling related data through proxies and procedural code.
