Create & Update (field types)

[Paul]

Looking at the Batch update, I see this code:

## Update Jenny's record
put "47" into tDataA[tClientsTableID]["87654321-abcd-1234-cdef-1234567890ab"]["age"]
put "110000" into tDataA[tClientsTableID]["87654321-abcd-1234-cdef-1234567890ab"]["income"]

It looks like that long UUID references Jenny's account. Which would be available after the user logs in.
But what's that reference to tClientsTableID? Could it be the table where "age" and "income" are stored?
Maybe. But you wouldn't name a table "tClientsTableID". So I'm probably wrong.

Question: If I have a record with many fields, does the whole record get written over or just the field or fields I'm updating? 

Question: Does this mean fields don't have an intrinsic type and store everything as a string? (or text) Numbers too?
