Hello, all the people with skills or interest on PI. I think a good topic for study is the proper or better method to expose data from PI to another systems, I personally use two ways:
1) Use of OLEDB to PI as relational DB. This allow to use SQL sentecences and you can go up to Web service creation, and from that your imagination is the limit!!
2)You can use PI-SDK with the functions and integrate to the apps.
I guess that all depends of the size, requirements, and enviroment of your app and of course the area of the skills of the developer of PI Adm.
Come on I'm waiting for others PI Enthusiastic...

I have also started using the PI OLEDB Provider mainly for the fact that my DataLink Client cannot handle large samples (I am restricted to excel 2003) and for the fact that everyone here that wants data know a little SQL. I suppose my next adventure is with the SDK.
And of course you can make

Exposing data from PI to any system
Thu, 10/09/2008 - 21:05 — PIAdminThe majority of my applications use the PI-SDK. There was talk last year of OSISoft restricting the SDK to certified applications. (IMO there are a lot of legacy SDK and API based apps out there and I'm not sure if this is practical). Anyway, since then we've been using OLEDB where data throughput isn't critical. We've been making use of SQL Server and linked servers in some applications and this has been quite reliable so far (although not without problems). I'm very used to the PI-SDK now and that's still my weapon of choice if possible.
