What does ADDI data store analysis reveal about a VSAM file used by multiple COBOL programs?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'The VSAM file's current DASD utilization and compression ratio on the storage subsystem'. ADDI data store analysis enumerates every program that accesses a given VSAM file and identifies the access patterns, crucial for understanding data coupling during service extraction. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
