We have a PI Server with around 20k tags.
One of our customer built Web App which is Java based and using jdbc data access product to access the data and show it as a trend on it.
the user will select one tag and period for a trend.Some tags have 1 sec, 3 sec, 5 sec and 30 sec data.
The data sample are as follows
- 1 tag, 1 week 10 min avg data
- 1 tag, 1 month 10min avg data
- 1 tag, 6 months 10min avg data
- 1 tag, 1year 10 min avg data
- 50 tags, 6 months 10 min, 1day avg avg data
- 50 tags, 1yesr day avg data
We are trying other data fetching possibilities, right now we tried web services based data access.
We need some guidance and best solution for above data fetching issue.
The option I see
- Web API
- PI AF SDK
- PI SDK
- Web Service
Also if there any other indirect method like developing AF SDk Wrapper as data provider kindly let us know.
