In a broad sense, accessing IMS means telling IMS to perform work for you.

• You can write application programs that tell IMS what to do.
• You can use existing application programs that tell IMS what to do.

These application programs can run in many different environments. They tell IMS what to do by calling a number of standard IMS functions through standard APIs: DL/I and JDBC⁴.
