File Compare

File Compare's architecture is centered around a comparison engine, a report generator, and integration with the z/OS environment. The comparison engine is responsible for analyzing the data within the datasets, identifying differences based on predefined criteria. The report generator then produces detailed reports that highlight these differences.

The tool uses JCL for job submission and execution. Configuration files store comparison settings, such as record lengths, key fields, and data type definitions. The tool does not expose external APIs.

Security is managed through the z/OS security system, which supports authentication methods like RACF and uses access control lists (ACLs) for permissions. The tool integrates with z/OS logging for auditing. The main components communicate through the z/OS operating system.

The tool's design prioritizes efficient processing of VSAM and QSAM files, ensuring optimal performance within the z/OS environment. The tool's architecture is optimized for z/OS, ensuring efficient processing of VSAM and QSAM files. The tool's main advantage is its deep integration with z/OS.
