I have developed a .net web portal which publishes data from any DB or web services. I want to PI AF data to be accessed and publish in my portal.
Which is the best way to connect and why.
Among the different developer technologies to connect to the PI and AF servers, I would encourage you to check out the following two:
Both products are undergoing active development (see product roadmap here).
You may also want to check out the SQL access technologies, OLE DB Enterprise and ODBC Provider.
I don't think there is a "best way" to connected, it depends on your needs. The SDK will give you the most capabilities, while PI Web API is good for basic stuff, but can get a little complex depending on what you are trying to do. The SQL access if good if you need to do more complex queries. My preference is to use the SDK because it is the most developed. But If I had a lot of users accessing data in a simple way, I would look to the PI Web API, because it can use indexing, does caching, and works well for situations where you have a lot of concurrent connections.
Thanks a lot Daphne and Lonnie
