Product Overview

DB2 for VM and VSE architecture comprised several key components, including the Database Manager, System Services, and Data Communication Services. The Database Manager handled SQL processing and data access. System Services provided core functions like security and logging.

Data Communication Services managed network communication using SNA. These components communicated through internal interfaces and system calls. The database used VSAM (Virtual Storage Access Method) for data storage.

The system supported a native API for application integration, with languages like COBOL and Assembler. Given the end of support, organizations should migrate to modern architectures. Db2 for z/OS offers a similar architecture on a supported platform.

Open-source databases like PostgreSQL provide alternative architectures based on client-server models and standard protocols like TCP/IP. Migration involves re-architecting applications to align with the new database platform.
