• System: Use cases seize purposeful necessities that specify the intended behavior of the machine.
• Goals: Use Instances are normally iNitiated by a user to meet desires describing the sports and editions worried in attaining the intention.

Actors are represented using lines with the name of the actor written below the road. To Constitute an actor’s participation in a device, a line is drawn between the actor and the use case. Boxes around the use case constitute the machine boundary.

Characteristics associated with use cases are:

• Organizing useful requirements
• Modeling the desires of system consumer interactions
• Recording situations from cause occasions to last dreams
• Describing the fundamental direction of moves and first rate go with the flow of Events
• Permitting a user to get entry to the capability of any other occasion

The steps in designing use cases are:

• Identify the users of the system
• For every category of users, create a person proFile. This includes all roles played via the customers applicable to the device.
• Identify sizeable dreams related to each position to assist the device. The gadget’s cost proposition identifies the sigNiFicant position.
• Create use cases for every aim related to a use case Template and maintain the equal Abstraction degree for the duration of the use case. Higher level use case steps are handled as desires for the lower degree.
• Structure the use cases
• ReView and validate the users
