Data modernization
How mainframe data reaches modern systems without losing accuracy or control: moving VSAM and IMS data to relational tables, replication and change data capture, virtualization and streaming for analytics, EBCDIC and packed-decimal pitfalls, and keeping one system of record.
What you will be able to do
- Explain how VSAM records and IMS hierarchies map to relational tables and what changes for programs
- Compare change data capture, virtualization, streaming and batch extracts for analytics access
- Convert mainframe data correctly by handling EBCDIC, packed, zoned and binary fields field by field
- Apply data quality, governance and security practices while keeping a single system of record
Lessons
- From VSAM and IMS to relationalMoving data from VSAM files or IMS databases into relational tables means redesigning record layouts as tables, keys and relationships, and changing how programs read and write…
- Replication, change data capture and analytics accessMany systems need mainframe data without changing where it lives. Change data capture copies committed changes as they happen; virtualization lets tools query the data in place;…
- Conversion pitfalls, quality, governance and the system of recordMainframe data uses EBCDIC text and numeric formats such as packed decimal that other platforms do not understand. Converting it wrongly corrupts data silently.
