What is an Entity (Feature)?
Any thing in which the business has an interest? (too vague)
A synonym for a relational table?
- Implementation-specific; misses the point
An information container in 1st normal form which:
- Records a fixed set of attributes
- Holds 0 to n occurrences
- Is an abstraction of some real-world concept
- May or may not map to a physical table in the database
Entity: Any distinguishable person, place, thing, event, or concept about which information is kept.
