Primes¶
- Equivalence-Preserving Rewriting
- A second compression follows: the equivalence relation, once made explicit, is reusable across many cost criteria — the same relational-algebra equivalences serve cost models for spinning disk, SSD, distributed shuffle, and in-memory engines, and the same logical-equivalence laws serve proof shortening, proof clarification, and prover-friendly rewriting.
This sourceStandard database text covering cost-based query optimization, relational-algebra equivalences, set-versus-bag (duplicate-preserving) semantics, and cost models parameterized by storage/access characteristics — supports both the reusability of equivalences across cost models and the set-vs-bag grain hazard.

- Return Path
- It is a distinct designed subsystem, not the forward channel run in reverse.
This sourceTreats transactions, rollback, and recovery (Ch. 17–19) as machinery distinct from the forward commit path.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
