## Detailed Description

a simple price database for gnucash.

The PriceDB is intended to be a database of price quotes, or more specifically, a database of GNCPrices. For the time being, it is still a fairly simple database supporting only fairly simple queries. It is expected that new queries will be added as needed, and that there is some advantage to delaying complex queries for now in the hope that we get a real DB implementation before they're really needed.

Every GNCBook contains a GNCPriceDB, accessable via gnc_book_get_pricedb.
