This figure shows the PGQL on RDBMS architecture. It is explained in text after the illustration.
The illustration contains two boxes (top and bottom) with a double-arrowhead line with the label JDBC between them.
The top box is labeled PGQL on RDBMS, and lists some Java APIs (Query execution, PGQL to SQL).
The bottom box shows the scalable and persistent storage (Oracle Database) that includes PL/SQL packages, PG Schema (VT$, VD$, GE$, GT$, IT$, SS$), SQL-based graph query, SQL-based graph analytics, OLS Security, Compression, and Oracle Text Index. Oracle Database communicates with the PGQL on RDBMS component.
