As with so many other data structures manipulated in PL/SQL, you don’t have to worry about freeing up the memory associated with these instances.

You can “project” JSON data relationally, extracting content from within the JSON document, thereby making it available for relational processes and tools.

You can even query, right from within the database, JSON data that is stored Oracle Database 12c Release 2 added several predefined object types to PL/SQL to allow fine-grained programmatic construction and manipulation of in-memory JSON data.

You can introspect it, modify it, and serialize it back to textual JSON data. If you can query and manipulate JSON data in Oracle Database tables with SQL, why do you also need PL/SQL object types?

You can use the object types to programmatically manipulate JSON data in memory, to do things such as the following: Overview The primary PL/SQL JSON object types you will use are JSON_ELEMENT_T, JSON_OBJECT_T, JSON_ARRAY_T, and JSON_SCALAR_T. Instead, you first read data from a table into the appropriate instances of the object types or construct the instances through parsing and other operations directly in your PL/SQL code.

Database developers should learn about JSON in Oracle Database and get really good at building APIs with PL/SQL packages and Oracle REST Data Services.
