Relevance Criteria for Concepts
It has been attempted to name only concepts that fulfill the following
four requirements.
- R1
- The concept must be specific to temporal databases.
Thus, concepts used more generally are excluded.
- R2
- The concept must be well-defined. Before attempting to name
a concept, it is necessary to agree on the definition of the
concept itself.
- R3
- The concept must be well understood. We have attempted
to not name a concept if a clear understanding of the
appropriateness, consequences, and implications of the
concept is missing. Thus, we avoid concepts from research
areas that are currently being explored.
- R4
- The concept must be widely used. We have avoided concepts
used only sporadically within the field.
