These definitions become very important asyou start to allocate responsibilities to those classes.The relationships to be identified are those needed to support the collaborationsmodeled in the use-case Interaction diagrams. The attributes to be identified are the“obvious” properties of the identified classes. More attributes may be defined duringlater Class Design.For each identified analysis class, determine if any of the analysis mechanisms apply.To make this decision, the Supplementary Specification may be needed.Refer to the following slides if needed:• Example: Finding Boundary Classes – p. 6-16• Example: Finding Entity Classes – p. 6-20• Example: Finding Control Classes – p. 6-24• Describe Responsibilities – p. 6-37• Finding Attributes – p. 6-42• Finding Relationships – p. 6-44• Example: Describing Analysis Mechanisms – p. 6-556 - 65
