I have always had a hard time remembering which to use when it comes time to query external data in my Kynetx apps.
Dataset:
I like to think of datasets as presents. “A set that can’t be changed once given”. Datasets are a one time query done in the global block of a ruleset that can’t be modified once the global block has been executed.
I like to remember datasources as a stream. I can query a datasource in the pre block of any rule and dynamically generate the query parameters that are used in the query. “Go to the source of the stream”.
Gratuitous day 21 Grace face
