NOTE THAT I AM ONLY LOOKING FOR ADVISE ON WHICH SOFTWARE(S) TO USE FOR DEVELOPING THE APPLICATION. I AM NOT LOOKING FOR THE ACTUAL APPLICATION AT THIS TIME. THAT WILL COME LATER IN A DIFFERENT PROJECT.

I am looking for a cost-effective solution for time-series <nobr>[database][1]</nobr> application that can be programmatically accessed by VB.NET.

DATABASE - The database will store 1 minute data (real number) for 1000 tags (e.g. tag0001 to tag1000) for 2 months. Data compression will be a desirable feature for the time-series database.

<nobr>[PROGRAMMING][1]</nobr> FEATURES - I should be able to calculate a new tag e.g. tag0999 just by writing a simple expression in VB like

if tag001>tag002, then tag0999 = tag001-tag002 else tag0999=tag003+tag004.

TRENDING - An excellent trending feature including for calculated tags is a must. I donot want to store a calculation just for trending i.e. I should be able to trend tag001+tag002 without storing this sum in a new tag first.

<nobr>[WEB][1]</nobr> BASED - A web-based deployment of trends is highly desirable.

All of the above can be done by [[url removed, login to view]][2]'s PI software, but I am looking for a much cheaper solution. One example would be (<nobr>[MySQL][1]</nobr> + Dundas Charts + VB.NET) but I am not sure if this can be done.

Can someone please advise on a workable and cheap solution.
