What is Online Shopping Cart?
An online shopping cart software is part or equal to e-commerce software online. This software runs on a web server and allows visitors to choose things for purchase. Additionally, customers who shop online can create a wish list of products to buy using this software.
The goal of the software is to aid online merchants, particularly with big client records. It is done by providing them with at least a simplified self-service option. In addition, merchants can save time and money, and keep the customers happy by delegating the task to the shopping cart.
Define Activity Diagram
UML defines the activity diagram as an effective diagram in showing the shopping cart’s behavior. This flow chart illustrates the interaction between the software and its users. This is done by helping them visualize the shopping cart’s functionality in various degrees of detail.
UML activity diagram is also used to describe and emphasize the use case diagram and its processes. It models the software’s actions, functions, and processes. It is one of the Shopping Cart UML diagrams but only shows the shopping cart’s dynamic behavior.
Shopping Cart Activity Diagram
The example activity diagram expands the shopping ideas. It is shown in the detailed illustration to enlighten the programmers.
As seen in the illustration, we used the swimlane with three partitions. The left portion shows the customer lane.
The right partition is the seller’s lane which shows the seller’s control and activities.
Now, the shopping cart’s scope and activities were in the middle. This is to show that the software acts as the middleman between the seller and the customer. Therefore, the software is accessible to both users.
To access the shopping cart, the users must first have their account logged into the software. It shows the users and the system interaction and the activity flows.
You can add more to this concept and it is up to you how would you draw your activity diagram. But, make sure that you have precise information and include the important decisions (actions).

How to Draw Activity Diagram?
Time needed: 5 minutes
Here are the steps in developing (designing) the activity diagram.
- Step 1: Familiarize Activity Diagram Symbols
Programmers must first become familiar with the symbols in order to build an activity diagram. This pinpoints the system’s flow of interactions.
- Step 2: Identify the flow of actions.
The action flow must be identified in this step. It will be based on your use case diagram. Actions describe the series of activities when a user invokes the hotel room booking.
- Step 3: Involve the Actors (users) included.
Actors carry out their actions on things, transforming them into other objects or changing their state. This actor is someone or something that interacts with the system.
- Step 4: Trace the flow of activities.
To make a flow or path for activities, make sure you know that the flows can be sequential, branching, or run.
In conclusion, we have learned what is an activity diagram and its importance. An activity diagram is a crucial tool for building a shopping cart, to sum up.
Additionally, the activity diagram works best with the other UML Diagrams. See also the provided Related Articles.
