Thank you both for the responses, I think I have a starting point now, and it looks like I need to do quite a bit more reading.
To make things simpler I will use a table in the wp database. My next step is to figure out where the php code needs to be to either update the post or make the data available to the post. Ideally the table would have selectable field/sort by capability.
I think one option is to use a special template (I need to read more on this)
Second option could be an addon called phpexec, executing php code embedded in the post, I am concerned that this might introduce a security issue.
I should note that this is my very first time looking at wordpress so I am slowly poking my way through.
