Like on BigQuery DWH manage Json arrays structures by offering on SQL (T SQL) tables schemas , this new column type ==> RECORD
According
- to deal with JSON arrays and their children columns (perhaps new arrays)
- avoid to store json data on a nvarchar column
- to deal on RAW / Staging / Bronze layers with JSON formats (from files & API results)
- to unnest / flatten after on silv
- Something more relevant the nvarchar column
- Avoiding to unnest/flatten on these tools
- er & gold layers , thanks to UNNEST SQL instructions
ETL/ ingestions tools schema mapping will appreciate that
