What is Datasource and why it is needed in Helical Insight (HI)
A data source is a location from which the data required for creating a report is fetched. The data may be stored in databases, csv files, excel sheets, etc. at different locations or accessed through different applications requiring their own drivers. For this reason, HI needs to connect to these data sources, by providing the location of the data source and its access credentials.
