9 About PGQL Property Graphs

You can create PGQL property graphs over data stored in Oracle Database. You can perform various graph analytics operations using PGQL on the graphs.

The following sections explain PGQL property graphs in detail:

• Creating PGQL Property Graphs on Oracle Database Tables
  The CREATE PROPERTY GRAPH statement in PGQL can be used to create a view-like object that contains metadata about the graph. This graph can be queried using PGQL.
• Creating a PGQL Property Graph By Importing a GraphSON file
  Using the GraphImporterBuilder API, you can create a PGQL property graph by importing graph data from a GraphSON file.
• Using JSON to Store Vertex and Edge Properties
  You can adopt a flexible schema approach in a PGQL property graph by encoding the vertex and edge properties as a single JSON value. You can then map this to a property value in a PGQL property graph.
