This graphic shows how an application can access the TimesTen database engine through one of several methods:
Use the ODBC driver to the SQL or PL/SQL engine.
For Java programs, use JDBC to access the ODBC driver.
For C++ programs, use ttClasses to access the ODBC driver.
Pro*C programs access ODBC driver through the OCI interface.
ODP.NET programs access ODBC driver through the OCI interface.
The OCI interface accesses the ODBC driver.
Open Source Language programs, such as Python and Node.js, access TimesTen through the ODPI-C interface, which in turn uses the OCI interface.
