Faceted classification - Faceted classification organizes information through several distinct characteristics, called facets, that can be combined to describe or retrieve an item.
Fact table - A fact table is a table in a dimensional data model that records measurable business events, observations or relationships at a defined level of detail.
Fail-stop - Fail-stop describes a failure behavior in which a component halts instead of continuing to produce externally visible erroneous results.
Failure detector - A failure detector is a mechanism that provides information about whether components in a distributed system may have failed.
