In a similar way to identifying entities, look for nouns or noun phrases in the users’ requirements specification. The attributes can be identified where the noun or noun phrase is a property, quality, identifier, or characteristic of one of the entities or relationships that you’ve previously found.
By far the easiest thing to do when you’ve identified an entity or a relationship in the users’ requirements specification is to consider “What information are we required to hold on . . .?”. The answer to this question should be described in the specification. However, in some cases, you may need to ask the users to clarify the requirements. Unfortunately, they may give you answers that also contain other concepts, so users’ responses must be carefully considered.
