Overview of the REST Query Service

The REST Query service contains APIs to fetch data from the Historian database. You can fetch data such as the latest data point of a tag or data points for a duration. Using these APIs, you can also work on aggregation techniques like average, minimum, and maximum values. The REST query container exposes port number 8989 for querying the data.
