Object diagrams & filmstrips

  • Object diagrams are a more refined and concrete representation of a class diagram. It helps to view the objects of the classes and the relationship between the objects. They help the user understand the complex relationships between objects. To understand this, they are used to capture snapshots of a particular time when or situation during program execution. Each object has an instance name and some attributes. 
  • E.g. An Object Company will have instance name XYZ with attributes company_size, company_location (company_name: Company). Another object will be employee with instance name as name of employee and attributes employee_name, employee_age (employee_name : Employee)
  • Sequence of object diagrams are referred to as Film strips. This is because the object diagram is considered as a snapshot. Like snapshot, an object diagram is taken for a particular situation.
