I've been using Len Silverstein's Universal Data Models for 15 years. You'll be writing to lots of tables and will want views for your common aggregates. But you'll have the common tables you'll need, the patterns for those you don't and be able to handle new requirements with minimal change.

There is no Customer table.

As per my comment elsewhere, this open source project implements a lot of that book (I can second the recommendation):

In a similar vein, I recommend David Hay's "Data Model Patternns: Conventions of Thought". It's more focused on the concept model side, but with awareness of how models are implemented in db schemas and the trade-offs involved.
