This figure shows the communication flow of PL/SQL components in TimesTen.
The application communicates with the API (such as OCI or JDBC), which is shown as a layer on top of ODBC.
ODBC communicates to the SQL parser, the SQL compiler, and the PL/SQL compiler.
The SQL compiler communicates to the SQL execution engine.
The PL/SQL compiler communicates to the SQL parser and produces the compiled PL/SQL procedure, which communicates to the PL/SQL execution engine.
The PL/SQL execution engine communicates to the SQL compiler and the SQL execution engine.
