[Orgmode] Org and financial data

[Memnon Anon]

Hi!

A new year has started and I try to get even more organized.
So, I think it is time to keep track of my financial data, and
I think orgmode is the way to go.

Yet, I am not sure how to keep the structure.
I started with something quite simple like using a date structure
and tables:

*2008
**January
***01
| What            |  Cost |
|-----------------+-------|
| Milk            |  0.50 |
| Apples          |  1.50 |
| Butter          |  0.89 |
|-----------------+-------|
| Sum             |  2.89 |
|-----------------+-------|
| Library Penalty | 13.50 |
| Library Copies  |  3.00 |
| Power Bill      | 35.00 |
|-----------------+-------|
| Sum Total       | xyz   |

But having a closer look at it, this does not seem that flexible.
Using ColumnView to display the sum of a day might be one idea,
adding tags like food, bill, wasted (Library Penalty :) etc. is 
another thing that comes to my mind.

Orgmode became so flexible and powerful, and I still have no clue about 
all its features. I am sure there are people out there doing what I am
planning to do.

So, what is your setup?
How do you use orgmode to keep a record of where your money goes and 
comes from?

I am sorry, this mail is a bit off topic.
But, as I said, my org knowledge is still quite limited and it would be
a colossal waste of time to enter data for weeks, just to find out that
a different format is more feasible and converting everything.

Thanks, have a nice day.
