Collection template types
Keywords: collection
Collection template classes allow defining collections with different characteristics. In ODABA, those characteristics are stored as properties for the collection. Hence, collection template types are converted into corresponding collection properties, which could be defined as well.
When appropriate template classes have been implemented, one may define collection types for transient members. In this case, collection types are treated in the same way as user-defined template classes, which cannot be stored to the database.
