Codd, where all data is represented in terms of tuples, grouped into relations.

Flat File and Custom Data Format Support
- Flat Files – such as comma- and tab-separated value files.
- Fixed-width Files – like dumps from databases or certain EDI-like formats.
- Tagged Files – which contain multiple row types within a single data stream.
- Hybrid Files – those that contain mixtures of the above qualities.
