Parent Issue

Part of #549 - New learning session on data engineering

Phase

Phase 2 - Restructure Existing Sessions (FINAL STEP)

Description

Complete the final renumbering and restructuring to transform S11 into S4 and renumber all modules throughout the course. This is a comprehensive refactor that touches many files and should be done carefully in one pass.

Tasks

Session Restructuring

• Rename s11_data_engineering/ → s4_data_engineering/
• Delete empty s4_debugging_and_logging/ directory (all modules moved out)
• Verify S5-S10 directory names remain unchanged

Module Renumbering

Renumber ALL modules throughout the course:

S1 (M1-M4 → M1-M5)

• M1-M4 stay the same (Command line, Package Manager, Editor, Deep Learning)
• New M5: Boilerplate (moved from old M15)

S2 (M5-M9 → M6-M10)

• M5 → M6: Git
• M6 → M7: Code Structure
• M7 → M8: Good Coding Practice
• M8 → M9: DVC
• M9 → M10: CLI

S3 (M10-M11 → M11-M13)

• M10 → M11: Docker
• M11 → M12: Config Files
• New M13: Logging (moved from old M14)

S4 (New → M14-M15)

• M14: Data Labeling (new)
• M15: Data Pipelines (new)

S5 (M16-M19 → M16-M19) - NO CHANGE

• Verify M16-M19 stay the same

S6 (M20-M21 → M20-M21) - NO CHANGE

• Verify M20-M21 stay the same

S7 (M22-M26 → M22-M26) - NO CHANGE

• Verify M22-M26 stay the same

S8 (M27-M28 → M27-M28) - NO CHANGE

• Verify M27-M28 stay the same

S9 (M29-M31 → M29-M32)

• New M29: Profiling (moved from old M13)
• M29 → M30: Data Loading
• M30 → M31: Distributed Training
• M31 → M32: Inference

S10 (M32-M34 → M33-M36)

• M32 → M33: Documentation
• M33 → M34: Hyperparameter Optimization
• M34 → M35: High Performance Clusters
• New M36: Debugging (moved from old M12, optional)

File Updates

• Update all markdown files with new module numbers
• Update all session README files
• Update all cross-references throughout the course
• Update timeplan.md with final structure (S4 = Data Engineering)
• Update main course overview/README
• Update any navigation/index files
• Remove temporary S11 references

Verification

• Run link checker to ensure no broken links
• Verify module numbers are sequential and correct
• Verify all cross-references work
• Ensure timeplan reflects new S4 as Data Engineering (Day 4)

Dependencies

• Blocks ALL: Sub-Issues [Refactor] New learning session on data engineering #549.5, [Refactor] New learning session on data engineering #549.6, [Refactor] New learning session on data engineering #549.7, [Refactor] New learning session on data engineering #549.8 (all modules must be moved first)
• Should be the LAST task in the entire refactor

Acceptance Criteria

• S11 successfully renamed to S4
• Old S4 directory removed (empty)
• All modules correctly renumbered throughout entire course
• All cross-references updated and working
• Timeplan shows S4 as "Data Engineering"
• No broken links in entire codebase
• Module numbering is sequential (M1-M36)
• Course structure matches the new plan from issue [Refactor] New learning session on data engineering #549

Notes

• This is a large, comprehensive change
• Consider creating a backup or working in a separate branch
• Test thoroughly before merging
• Update any CI/CD configurations if they reference specific modules
