This information is only required reading if you want to go and view the raw data stored by Thinking Stuff.

Firstly, we want to open the pgAdmin program that was installed at the same time that you installed PostgreSQL. To do so, click Start > Programs > PostgreSQL 8.1 > pgAdmin III. (Noting that you may have installed a different version of PostgreSQL, or different version of pgAdmin).

The pgAdmin program starts up. But, it hasn't connected to anything yet. The available servers will be listed in the left pane of the program.

If you installed PostgreSQL just so you could use Thinking Stuff, there will probably be only one server to choose from: "PostgreSQL Database Server 8.1.3 (localhost:5432)". (Again noting that you may have installed a different version of PostgreSQL, or maybe you chose a different port to the default of 5432).

Anyway, select that entry by left-clicking it. Then right-click to bring up a little pop-up menu. Left-click the "Connect" entry on that little menu.

If you are asked to enter your password, do so, and click OK.

If it hasn't already done so, expand the "Databases" folder by clicking the (plus) symbol. All your databases will be listed.

Select the database you want to view by left-clicking it. If there was a red cross over the cylinder icon, you just have to wait a couple of seconds for that database's details to be retrieved. Once the minus symbol appears just to its left, click it to expand the folder.

Expand the "Schemas" folder.

Under "Schemas", expand the "public" folder.

Under "public" expand the "Tables" folder.

And now you're looking at all of the tables that Thinking Stuff uses to store its data.

Scroll to the end. Tables starting with "z" are data tables - currency prices are stored there.

Any other table is an administrative table that you can view, but please do not change anything! You should read the Licence Agreement which details the extraordinary amount of money I will charge you to fix anything you break.

Right-click on the table you want to view, and choose "View Data" from the pop-up menu.

You are now looking at the raw data. That's it. You can edit each cell individually, if that's what you want to do.

If, however, you want to export the data to a text file, you need to use the Query Tool, which is accessible from the "Tools" menu within pgAdmin.

In the Query Tool you specify your query, and then click "Query" > "Execute" from the menu. When you have the results back, choose "File" > "Export", and configure how you want the data exported.

The "specify your query" part requires knowledge of SQL, and is way too big a topic to cover on this website. However, to show all the data from one of the tables, type in something like this:

select *
from zoanda_eurusd_30mi
order by tdate
