I would be grateful if you could give me an example of handling unstructured data.
What exactly do you mean by "unstructured data"?
I am wondering about the unstructured data processing described in the image below.
For example, Thingworx can take in unstructured data as a string (maybe it's JSON or XML, but it doesn't have a pre-defined structure) and store it in a Stream or DataTable column.
You might have a 'Person' type record, but you don't know if there's a first or last name, or if there's an address or phone number or date of birth. But, you can still store this in the data store, whether it be Neo4j, PostgreSQL, DataStax Casandra, or H2.
