This chapter provides tutorial notes and examples on UML sequence diagram and notations. Topics include introduction to UML sequence diagram; graphical notations to describe object lifeline, communication messages, execution specification, sequence frame, etc.
A Sequence Frame Notation is a graphical notation used in a UML Sequence Diagram to provide a boundary to enclose all messages and lifelines of a communication sequence.
A Sequence Frame Notation is drawn as a large rectangle with a pentagon at the top left corner. "sd" followed by the sequence name are written in the pentagon.

to perform a user login process can be described as a communication message sequence with sequence frame.
This frame can be drawn with a Sequence Frame Notation in a UML sequence diagram as shown below:
