[]use Case of software engineering management

• Use Case id:satellite#1
• Use case Name:read the satellite input data
• Actor that initiates the use case:

–actor 1:engineer

–actor 2:programmer

• Other actors, if Any:none
• Statement of the purpose of this use case:

This is the engineer input the satellite data into the system

• Preconditions (must be true before the-case can be "executed"):

, Haven Engineer can login in the system and can input the data, can receive the successful return message

• Primary scenario (to describe the main action of the):

–open the main menu and click at "Input data"

, Haven System can return the successful message to the screen

• Post-conditions (What must is true after the "executes"):

, Haven Engineer can log out or return to main menu.

• Alternative scenarios (Exception handling):

–give The engineer the warning message

• Comments:response time shall is less than 1 seconds.

• Use Case id:satellite#2
• Use case name:update satellite data
• Actor that initiates the use case:

–actor 1:engineer

–actor 2:programmer

• Other actors, if Any:none
• Statement of the purpose of this use case:

The engineer update (change or delelte) of the satellite data in the system

• Preconditions (must be true before the-case can be "executed"):

, Haven Engineer can login in the system and can has the power to update the data, if the data has already updated th En return a successful message

• Primary scenario (to describe the main action of the):

–open the main menu and click at "Update Data"

, Haven System can return the successful message to the screen

• Post-conditions (What must is true after the "executes"):

, Haven Engineer can log out or return to main menu.

• Alternative scenarios (Exception handling):

–give The engineer the warning message

• Comments:response time shall is less than 1 seconds.

• Use Case id:satellite#3
• Use case name:give warning for potential satellite collision
• Actor that initiates the use case:

–actor 1:the System

• Other actors, if Any:none
• Statement of the purpose of this use case:

This is the case of the system to give a warning message to the user for potential satellite collision

• Preconditions (must be true before the-case can be "executed"):

, Haven user can login in the system and has input the right satellite data, if there would a potential satellite coll Ision then return a warning message

• Primary scenario (to describe the main action of the):

–open the main menu and input the satellite data

–click the "Detect" button and the system would calculate the input data

, Haven System can return the message to the screens, whether or not there would be a satellite collision

• Post-conditions (What must is true after the "executes"):

, haven user can log out or return to main menu.

• Alternative scenarios (Exception handling):

, Haven Engineer Test the system at regular intervals

• Comments:response time shall is less than 1 seconds.
