PRESSTO

The architecture of PRESSTO comprises several key components: the compression engine, the dataset management module, and the API interface. The compression engine is responsible for the actual data compression and decompression processes. It utilizes proprietary algorithms optimized for z/OS environments to minimize storage space and maximize performance.

The dataset management module handles all dataset-related operations, including allocation, deallocation, and access control. This module ensures that datasets are properly managed and that compression operations are performed efficiently. The API interface provides a means for other applications to interact with PRESSTO.

It allows developers to integrate compression and decompression functionalities directly into their applications. The API is a native API, designed specifically for z/OS environments, and supports various programming languages commonly used on the platform. Communication between components occurs through internal system calls and memory structures.

The dataset management module interacts directly with the compression engine to perform compression and decompression operations. The API interface communicates with both the compression engine and the dataset management module to facilitate data compression and access. PRESSTO does not use external databases or storage mechanisms for its core operations.

It relies on the z/OS system services for data storage and management. The product integrates with the z/OS security infrastructure, such as RACF, to manage access control and permissions. There are no specific network ports or external network requirements for the core compression operations.

All operations are performed within the z/OS environment, utilizing internal system resources.
