Sequence 139 — T10 - CSV representation and encoding pitfalls
Context: Technology Gate B - Programmatic Data Management | Technology Gate
Source: CDMP Master Execution Manual
When / purpose
Understand why flat-file representation can create integration/quality problems.
What you should learn
- Delimiter/quoting.
- Headers.
- Encoding awareness.
- Blank vs null vs zero.
Resources / limits
Technology Competency Roadmap: active T6–T10 only. Detailed Technology Competency Reference: topic detail/readiness only.
Do this in order
- Inspect one Meridian CSV in a text editor and pandas.
- Create a harmless working-copy delimiter or quoting defect.
- Diagnose it without changing the canonical source.
Meridian application
Use Meridian synthetic files and database only for bounded practice.
Create / save
CSV defect note.
Stop / boundary
Stop before production data engineering, application development, advanced OOP, orchestration or distributed processing.
Completion gate
You can explain how representation affects parsing and quality.
