Trigger
Cron, event, manual dispatch or a condition on a source.
Narrative example
How public data becomes a publication.
- 1. The workflow acquires the value and its reference date.
- 2. It checks missing values, freshness and consistency.
- 3. It computes indicators or applies a model.
- 4. It compares the output with relevant gates and baselines.
- 5. It generates the card, alt text, provenance and duplicate hash.
- 6. It publishes or records an explicit skip/block.
From plain language to technical language
The same stages, with two sets of names.
| Plain language | Technical term |
|---|---|
| The system starts the work | Trigger |
| It retrieves information | Acquisition |
| It checks that it can be used | Validation / quality gate |
| It performs calculations | Compute |
| It decides whether to proceed | Decision |
| It stores results and information | Persistence / provenance |
Progressive path
From visible output to implementation.
Each level adds detail without forcing the reader to restart: enter at the most useful point and continue progressively.
Before method
Need a map of AI, data and algorithms?
The intermediate level explains data types, regression, classification, clustering, neural networks and automation.
General diagram
Choose the depth
One method, five reading levels.
The path starts with concepts and examples, moves through operational logic and software architecture, and reaches validation, frameworks and failure modes.
Level 1 — For everyone
- Where data comes from
- Why controls matter
- What a model produces
- Why supervision remains necessary
Level 2 — Operational
- Ingestion and normalisation
- Quality gates and scheduler
- Error handling
- Versioning and publication
Level 3 — Technical
- Feature engineering
- Temporal splits and baselines
- Bootstrap and calibration
- Metrics and drift
RPA in practice
Automation is not only execution: it is exception management.
Acquisition
APIs, feeds, files or pages with retries, timeouts and source dates.
Decision
Rules, models, quality gates and supervision determine publish, skip or block.
Trace
Logs, state, provenance, hashes and history make the process auditable.
