What happens when a top-level Asset account gets added?

The following rows are added in various tables:

** accounts **
f81bd224897ba77e5998139d7cc50be5|Assets|ASSET|be2788c5c017bb63c859430612e64093|100|0|1d61881fa764645df6f203834c0c3030|||0|0

** commodities **
be2788c5c017bb63c859430612e64093|CURRENCY|THB|Baht|764|100|1|currency|

** slots **

See http://wiki.gnucash.org/wiki/images/8/86/Gnucash_erd.png for the ER diagram for each table. Printing it out in color did much good for me.

1. No idea what "slots" table does.
2. Commodities table simply says that the account is of currency THB
3. We've added an Account named "Asset"
