Can you name the different elements with the collaboration diagram?

There are basically three types of elements of a collaborative diagram:

• Object - the interaction in a system always takes place between two objects. An object is always depicted by a rectangle with the name of the object. This is preceded by a colon and an underline.
• Relation - it is also known as an association which is always among the objects which are linked with the connection in a system. They are depicted by placing the qualifiers on both ends.
• Message - An instance of communication from one point to the other significant point or destination is a message. It always depicts the interaction that is offering between the objects in a system. The sequence of this interaction is directly shown by the number.
