Sequence Diagram for E-Commerce Website

Sequence Diagram for E-Commerce Website

The SEQUENCE DIAGRAM for E-COMMERCE WEBSITE is a form of interaction diagram that shows how a group of entities interact and in a specific order. It is used to understand and describe a series of processes on the website.

The E-commerce Website Sequence Diagram is created based on Unified Modeling Language (UML) that depicts the flow of messages between objects in a scenario. It’s composed of entities connected by lifelines, and the communications they exchange over time.

The importance of Sequence Diagram for E-commerce Website 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 comes with user decisions that results to more effective interaction. Being a programmer, these are the important roles that the Sequence Diagram for E-commerce Website should have.

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

UML Sequence Diagram for E-commerce Website

The UML Sequence Diagram for E-commerce Website is one of the methods used for project development. It is a useful tool for documenting the E-commerce Website needs and fleshing out its architecture.

The e-commerce website 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. These are helpful for displaying collaborations between items, and for defining objects interactions precisely.

Benefits of Sequence Diagram for E-commerce Website

  • Clarifies the concepts from UML use case.
  • Models the logic of difficult procedures or processes.
  • Examine how objects and entities work in series to finish the process.
  • Strategize and include the specified function of a scenario.

Simple Sequence Diagram (UML) E-Commerce Website

The E-commerce Website Sequence Diagram with Explanation is given to expound its ideas. This sequence diagram is shown and is based on the concept of Website Management.

You’ll be able to understand and educate yourself on how the E-Commerce Website works by creating this diagram. Because it determines the needed objects, actors and messages and their interactions.

As you can see through the illustration, the conditions and interactions are emphasized. These interactions are essential for the E-Commerce Website development. The series of messages are shown and labeled to guide you in building an E-Commerce Website. You can modify the design if you have more ideas. You can also add more features to this design and use it as your project blueprint.

The sequence diagram given shows 4 objects which are: the customer, e-commerce website, account server, item database and orders and deliveries. These objects were based on practical activities that happens in website management. The sequence of messages then were plotted below the objects to determine how the process is being performed.

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

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

Time needed: 5 minutes.

Steps in creating a Sequence Diagram for E-commerce Website.

  • Step 1: Familiarize Sequence Diagram Symbols

    Sequence Diagram Symbols – are used to create 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 e-commerce website, then your users would be the buyers, Admin and the sellers. You may ask them of the common activities that they do when doing task in online shopping. These 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 the unwanted errors.

    The gathered information from the targeted users are very useful in creating a sequence diagram. You just need to evaluate these data and pick the 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 interaction or messages among the objects. If you encounter some decisions or constraints, you will place alternatives depending on the situation.

    After that, you will can 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 the concerns with it.

Conclusion:

It is essential for you to know the diagrams used to design and develop the E-commerce Website. That is because you cannot perfectly create a fully-functional system without it. But if you create this sequence diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

The sequence diagram can be used to model the system’s interactions. These systems are also captured in sequence diagram, which describes the flow from one object to another. By completing the Sequence Diagrams per module or per processes, you will easily achieve your desired system. Check out our Related and Recommended Articles for more Learnings and Information.
