## Entries

- [Sequential Access](https://banes-lab.com/records/architecture/sequential-access.md): A design pattern that reads a source in its stored order through a cursor or scan, instead of looking records up one by one.
- [Forward-Only Processing](https://banes-lab.com/records/architecture/forward-only-processing.md): A rule or precondition that a stream is read once in order, keeping only rolling state, so no decision ever needs to revisit earlier input.
