db-lib is the oldest and simplest API, and the only API supported by
both vendors, which has some relevance when porting applications that
use the vendors' libraries. db-lib was the first API implemented by
FreeTDS, and is still the best one supported. Anything that can be
done in FreeTDS can be done through db-lib.
Paths come from the repository package-file index for the observed builds. They describe archive/package associations, not every file that will exist on a running system after maintainer scripts, alternatives, generated state, diversions, or installation choices.
Each row is recorded package-index metadata for one version, architecture, suite, and repository. Names, URLs, and sizes are source-reported; a link is a potentially mutable retrieval location, not an OpenFactory redistribution claim or proof that OpenFactory retained the artifact bytes.
