Well... I'm glad you liked the book, and yes, it needs more examples of
what AstDB can do.  I'll keep that in mind for the next time we revise
the material.

If you're coming from a traditional relational database mindset, the
AstDB is going to seem very weak.  What I tell people in my training
courses is that the AstDB database is simple way of storing key-value
pairs.  You simply use it to store and organize values, and then
retrieve one value at a time.  Contrast this with relational databases,
where you often run queries that retrieve more than one value at a time,
do joins across tables, order and filter the results, etc.

Hopefully that helps make things a bit more clear.
