Just wondering what the best database design is for this particular pset.

ATM I have a table for trades which serves to record all transacsatsions (buy and sell), each trade has an unique id, and associates with a user from the users table.

The problem I'm having his how to approach the portfolio section of the site. I could create a portfolio table with user id, symbol, and shares fields. However, it seems a bit redundant, as anything required for the portfolio can be calculated from the trades table. I.e sum of buys and sells of a symbol gives the total owned of that stock. Then do a lookup of the current price, and post that in the portfolio section.

However, that also seems suboptimal.

Anyoen want to share their schema?

Cheers,
