![]() ![]() The second Use Case is to Add Itemthat will be done by the Admin that needs to be taken care of. So, Select Use Case from the left and add it inside the Use Case Subject. As User will First Login and then He/She can proceed to order something. The first use case that is important for an Online Shopping System is Login. You can also change the Actors Line Color by Right Click -> Line Color. On the left side, pick the Actor Use case and just click wherever you want to add and change its name. So For Online Shopping, There are basically two Actors: Just click on it and Then Make it on the White Side and Give it the name Online Shopping System. The first step to draw a Use Case Diagram for Online Shopping is to Add a Use Case Subject From the left. Step 3: Draw a Use Case Diagram ✦ Add Use Case Subject: You can see on the left side all the use cases of the Use Case Diagram is shown and a whiteboard on the right side. Now you need to add a Diagram from Models -> Add Diagram -> Use Case Diagram. how the user actually interacts with the system.After Downloading, open Star UML and you can see a Blank View. Last point is separated because we are not going to model that. 2 minutes long The user can record message Recording of a message ends after 2 minutes or when the user stops recording Recording destroys the original message at chosen slot Sufficient level of battery is checked before recording message Message of a given slot can be replayed Sufficient level of battery is checked before replaying message Messages can be locked/unlocked Locked messages cannot be deleted or over-written by recording to the same slot User uses LCD display and buttons to interact with recorder More detailed description of system features. Software Engineering 12ġ3 Problem Statement The recorder stores up to 10 messagesĮach message is max. of 2 minutes Messages can be recorded, played back and deleted Messages can be locked/unlocked to prevent unwanted deletion/overwriting LCD display The first very basic description.
