Well... I'm not sure I know quite what you mean. In your example, you could create all of those Currency objects, then use Tangram to insert them into a database. That would be one script.

Then, in another script, you could tell Tangram to go and get you a particular Currency object. It would load the data from the database and hand you back a Currency object, just like the one you had created in the first script.

You're not actually eliminating select statements, because *someone* still has to do a select--even if it's not you, it's Tangram. :) But you don't have to worry about that select; you can just act as if you had created the Currency object in the same script.

Does that make sense?

There's a good introduction to using Tangram in WebTechniques.
