The task involves extracting information from a multi-layered JSON string in a Snowflake database.
SpecificTrap field is identified as the grouping field, and details like oid and value are extracted from the first layer array variables.
In SQL, due to its limitation with multi-layer data, indirect implementations through nested queries and grouping aggregation are required.
On the other hand, SPL (Structured Programming Language) directly supports multi-layer data access and allows object-oriented access to such structures.
