What is the best way to translate a relational database into a drupal based site.

In looking for modules i ran into the next modules.

nodefamily looks promissing to navigate through nodes. It promisses to be a directed graph so it MUST BE cool ;-)

views_fusion makes it possible to create joined views "fuse multiple views into one" It looks unmaintained since may 2007.

nodehierarchy looks like nodefamily.
