What are the different access methods available in VSAM?

There are three main access methods available in VSAM:

1. Keyed Sequential Access Method (KSAM): KSAM allows records to be accessed sequentially based on a specified key field.
2. Relative Record Data Set (RRDS): RRDS allows for direct access to records based on a relative record number.
3. Entry-sequenced Data Set (ESDS): ESDS provides sequential access to records in the order in which they were written to the dataset.

Each access method offers different advantages and is suitable for different types of applications in VSAM.
