At some point, nearly every developer encounters a common challenge: working with deeply nested JSON only to run into an arbitrary depth limit imposed by the database. In our case, that hard cap was set at 32 levels — sufficient for many scenarios but too restrictive for more complex or dynamic data structures. To address this, we decided to remove the limitation entirely.

One of the standout features of Oracle PL/SQL is the associative array — a versatile and efficient in-memory data structure that developers rely on for fast temporary lookups, streamlined batch processing, and dynamic report generation.
