Sequence Diagram for Online Shopping System

The sequence diagram for the online shopping system is an interaction diagram that shows the series of objects and messages and how they interact. This diagram helps software engineers and developers figure out what an online shopping system should look like and describes the process that is already in place.

A UML Sequence Diagram (also known as an interaction diagram) shows how online shopping operations are carried out. It captures the interaction between objects in a collaborative setting. The Online Shopping System Sequence Diagram is time-based and shows the order of interaction by using the vertical axis of the diagram to show time and the messages that are sent and received.

An online shopping system 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. The major goal of the online shopping system is to keep track of shopping, the internet, payment, bills, and customer information. It keeps track of all the information related to shopping, products, customers, and shopping.

The availability of internet businesses allows you to shop from the comfort of your own home. It’s difficult to find any in stores that are open 24 hours a day, seven days a week. Online Shopping systems can assist clients in obtaining merchandise and save time while shopping. The drawback of online shopping is the lack of trust.

Importance of Online Shopping System Sequence Diagram

The importance of online shopping system sequence diagram is that it could help understand the project requirements. This also helps in describing the existing processes of the project. The sequence diagram is quite valuable because it depicts the interaction between the items (object) and the system.

The sequence diagram involves major activities to define the workflow of the project. These activities come with user decisions that result in more effective interaction. Being a programmer, these are the important roles that the Online Shopping System should have.

A sequence diagram aims to define the sequence of events in the system to achieve the desired outcome. It is useful when you need to examine the behavior of various events in a single-use case.

UML Sequence Diagram for Online Shopping System

The UML Sequence Diagram for Online Shopping System is one of the methods used for project development. It is a useful tool for documenting the Online Shopping System’s needs and fleshing out its architecture.

The system’s sequence diagram is designed to represent a timeline that shows the series of interactions. Each object has a column, and the arrows indicate the messages that are sent between them. Sequence diagrams help display collaborations between items, but not so much for defining behavior precisely.

Developers frequently use sequence diagrams to model the interactions between items in a single-use case. They show how the various pieces of a system communicate with one another to perform a function, as well as the order in which the interactions take place when a specific use case is executed.

Sequence Diagram (UML) for Online Shopping System

The Online Shopping System Sequence Diagram with Explanation is given to expound its ideas. This sequence diagram is shown and is based on the concept of Online Shopping. The diagram presented here will show you a detailed illustration of the sequence of events that happen in the Online Shopping System. This designed sequence diagram can show programmers and readers the sequence of messages between the actor and the objects.

Sequence Diagram for Online shopping System in UML

The diagram shows the series of messages that occurred to complete the task of managing online shopping. The diagram portrays a single scenario which is very common for online shopping systems. This scenario is presenting the sequence of events and messages when a borrower borrows a book.

The sequence diagram given shows 4 objects which are: the system, system server, product database, and order product. These objects were based on practical activities that happen in online shopping. The sequence of messages was plotted below the objects to determine how the process is being performed.

You can add more to this and it is up to you how will you create your sequence diagram. Only be precise with your information and consider the decisions that should be included.

Steps in Building the Sequence Diagram for Online Shopping System

The tools used to build the sequence diagram were explained here.

Time needed: 5 minutes.

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.

Additional Knowledge on Sequence Diagram:

The Online Shopping System is a sort of interaction sequence diagram that shows how a group of items interacts and in what order. Software engineers and business experts use these diagrams to understand the requirements for a new system or to describe an existing process.

The Online Shopping System must have a designed diagram to define event sequences that will result in the desired outcome. The series in which communications appear is more important than the message itself. On the other hand, the majority of sequence diagrams will show what messages are transmitted and in what order they usually occur.

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. That is why the sequence diagram is designed to help programmers develop the system.

It offers its consumers a very convenient option by allowing them to save items in their shopping bags and purchase them later. Shopping on the internet is only possible for those who have a valid credit card, debit card, or internet bank account. You can expand your reach by selling directly online.
