Final answer:
The notation 0..* signifies 'multiplicity zero or more', meaning that there can be zero or any number of instances in an association within data modeling contexts like UML.
Step-by-step explanation:
The notation 0..* is used in various data modeling contexts, such as Unified Modeling Language (UML), to indicate multiplicity. When it appears, for example, in an entity-relationship diagram or a class diagram, it represents the number of instances of one entity or class that can be associated with another entity or class.
The correct interpretation of 0..* is multiplicity zero or more. This means that there can be zero or any greater number of instances of the entity or class involved in the association. It signifies that the association is optional, and there is no upper limit to the number of entities that can participate in it. For instance, if we had an entity 'Book' and another entity 'Author', a multiplicity of 0..* next to 'Author' would indicate that a 'Book' may have zero or many 'Authors' associated with it.
