Insurance data models...any tips on good starting point?

[aai_jj]

We have a client that has the typical online quote generator but is
looking to revamp that process and tie it in with other services he
can sell to other insurance clients. The application is still in its
infancy but could have the potential of blowing up in our face if we
don't plan accordingly.

The old website used a fairly simple RDB with a lot of array
manipulation done by the developers, but we'd like to make it a little
more object-oriented, maybe even consider an EAV modeling approach to
allow for the growth.

Are there any insurance data models out there to start from or is
anybody willing to share their experience on similar projects?

Any thoughts or direction would be greatly appreciated.

Thanks.
