# Concepts

- [Machine data](https://docs.enlyze.com/en/concepts/understanding-machine-data.md): What machine data is, how it is recorded, and why context matters.
- [Data sources](https://docs.enlyze.com/en/concepts/understanding-machine-data/data-sources.md): What data sources in manufacturing are and how ENLYZE captures machine data.
- [Variables & time series](https://docs.enlyze.com/en/concepts/understanding-machine-data/variables-and-time-series.md): What variables and time series are and how ENLYZE records machine data.
- [Production context](https://docs.enlyze.com/en/concepts/production-context.md): How order data gives meaning to machine data and what analyses this enables.
- [Downtimes](https://docs.enlyze.com/en/concepts/downtimes.md): What downtimes mean in production and how ENLYZE detects and classifies them.
- [Detection](https://docs.enlyze.com/en/concepts/downtimes/detection.md): How ENLYZE automatically detects downtimes from machine data.
- [Categories & assignment](https://docs.enlyze.com/en/concepts/downtimes/categories-and-assignment.md): Downtime categories and how reasons are assigned to downtimes.
