Steps in creating a Sequence Diagram for Online Shopping System.
- Step 1: Familiarize Sequence Diagram Symbols
Sequence Diagram Symbols – are used to create a Sequence Diagram to emphasize the system’s interactions in terms of its’ message sequences. Their symbols and applications must be familiarized before you build the Sequence Diagram.
Each of the sequence diagram symbols shows the overall System interaction. Emphasizing the System’s behavior would be much easier by using these Sequence Diagram symbols. - Step 2: Determine the targeted users
After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.
Your project is Online Shopping System for school, then your users would be the Staff, Admin, and the students. You may ask them about the common activities that they do when doing tasks online shopping. This information will help you in proceeding with the next step. - Step 3: Analyze the activities included
Analyzation is very important in creating a sequence diagram. It will help you understand the work of the diagram and avoid unwanted errors.
The gathered information from the targeted users is very useful in creating a sequence diagram. You just need to evaluate these data and pick useful information. Then you’re ready for the next step. - Step 4: Plot the Sequence Diagram
To plot the sequence diagram you will need the objects, messages, and lifelines. You will base the sequence of events (interaction) from the evaluated information to have the exact Sequence Diagram.
To plot your Sequence diagram, you need to place first the objects involved and their lifelines.
Then start building the series of interactions or messages among the objects. If you encounter some decisions or constraints, you will place alternatives depending on the situation.
After that, you will review all the events and interactions you’ve made and check if there are still missing. Creating the sequence diagram will help you figure out the needs of your project and your concerns with it.
Conclusion
Online shopping is a type of electronic commerce that allows customers to buy goods or services directly from sellers over the Internet via a web browser or a mobile app. It is the act or activity of purchasing products or services from websites and it provides efficiency for the shoppers.
