What is the purpose of sequence diagram?
The sequence diagram is a good diagram to use to document a system’s requirements and to flush out a system’s design. The reason the sequence diagram is so useful is because it shows the interaction logic between the objects in the system in the time order that the interactions take place.
What is sequence diagram in database?
A sequence diagram is a Unified Modeling Language (UML) diagram that illustrates how a group of objects interact and operate with each other sequentially. The sequence diagram consists of a group of objects that are represented by lifelines and the messages that they exchange over time during the interaction.

Where do we use sequence diagram?
You should use sequence diagrams when you want to look at the behavior of several objects within a single use case. Sequence diagrams are good at showing collaborations among the objects; they are not so good at precise definition of the behavior.
How do you define an object in a sequence diagram?
Object. In the UML, an object in a sequence diagram is drawn as a rectangle containing the name of the object, underlined.
