Pharmacy Management System Use Case Diagram

Pharmacy Management System Use Case Diagram

The UML use case diagram is the behavioral diagram that summarizes activities done in the pharmacy management system and its user details. It depicts the structure of the system’s behavior.

Additionally, the diagram consists of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall workflow of the pharmacy management system.

The use case diagram in software engineering shows the sample adaptive behavior of the pharmacy management system. It encapsulates the project’s functionality by incorporating use cases, actors, and their interactions.

Moreover, the diagram assists you in defining and organizing project requirements. This also provides a clear picture of the user and system relationships. Therefore, this diagram depicts the high-level functionality of a system including how the user interacts with it.

Importance of UML Use Case Diagram

To help the developers and enterprises in developing the system is the importance of the UML use case diagram. It includes the procedures from the viewpoint of users.

Furthermore, the diagram is the analysis methodology used to identify, clarify, and organize project needs. This diagram works best with other UML Diagrams for Pharmacy Management System. Other UML diagrams include activity, class, sequence, deployment, and component diagrams.

The sample system use case diagram includes actors, processes (use case), and their relationships.

Pharmacy Management System General Use Case Diagram

This diagram shows the general processes or functions that the system could do. These processes are based on the transactions done by the admin in managing their customers and medical information.

The general use case is the most common application of a use case diagram. The use case diagrams depict the system’s main components as well as the flow of information between them.

Use Case Diagram using Include and Extend

Use Case Diagram using Include and Extend is used to elaborate the proceeding diagrams. The terms include and extend in the use case diagram are known as indicators.

The label include is used to indicate that the sub-processes of the main processes must be included to complete the task. The Extend, on the other hand, declares that the sub-processes can only be performed when needed.

Manage Customers’ Information and Status Use Case Diagram

This is where the admin of the system could manage and monitor their customers’ information and status. In this process, they were able to trace the transactions made by the customers and the orders or purchases they access.

This is the process where the admin will have to manage the revenues and services or orders availed by the customers.

The medicines must be set with the appropriate prize and categories for better services. It is also easy for the customer to purchase if the pharmacy management is organized and presentable.

How to draw a Use Case Diagram?

Time needed: 2 minutes.

Here’s the complete guide on how to draw a use case diagram for pharmacy management system.

  • Step 1: Familiarize Use Case Diagram Symbols

    For beginners in the field of designing the diagram, you need first to familiarize the symbols to be used.

  • Step 2: Determine the targeted users

    The next step is to determine your targeted users. They will be the ones to use your project.

    You may ask the users about the typical activities done in pharmacy management.

  • Step 3: Analyze the use cases included

    The gathered information from the users needs to be evaluated to know the general use cases.

    From the general use cases, you will see the sub-cases that are included. But, only the useful processes and circumstances related to the pharmacy management system.

  • Step 4: Plot the Use Case Diagram

    To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information from the users.

    You need to place first the users involved.

    Then place the figured use cases included in doing the process.

    After that, you will trace the association of the use cases to know the interactions between the user/s and the system.

    Finally, put the container in the plotted diagram to separate the objects’ (users and system) scope.


The use case diagram is one of the methods that contribute to the pharmacy management system design and development. It helps developers know the possible inputs and scenarios that the project should process and perform.

Furthermore, you will find out the needed processes and connect them to the other UML Diagrams. The diagram is also applicable in modeling the software’s use cases (processes). It also captures the system’s flow from one process to the next.
