Activity Diagram for Library Management System

The activity diagram example for library management system is a UML behavioral model. It shows the system’s behavior by presenting the flow of activities from one to another. The possible flow of activities can be in order, split, or continuous.

Importance of Library Management System

The importance of the Library System Activity Diagram is that it enables interaction between developers and clients. This is done by helping them visualize the system’s functionality in various degrees of detail.

Activity Diagram Library Management System using Swimlanes

The Activity Diagram for Library System using Swimlanes is given to expound its ideas. This Activity Diagram using swim lanes is shown in different scenarios and is based on its users.

Activity Diagram (Librarian) – This illustration shows the activities and scenarios done when the librarian accesses the system. All the actions and decisions included are all emphasized here.

Steps in creating an Activity Diagram for Library Management System.

  • Step 1: Familiarize Activity Diagram Symbols

    First, Activity Diagram Symbols – are used to create an Activity Diagram which was presented here. Their symbols and applications must be familiarized before you build the Activity Diagram.
    Activity Diagram Symbols
    Start – is the beginning of the action is symbolized by a filled circle. A dark circle represents the initial node.
    Action – is a stage of an activity in which users or software accomplish a certain task. Actions are represented by round-edged rectangles.
    Decision – represented by a diamond and is used to symbolize a conditional branch in the flow. It has two or more outputs and a single input.
    Swim Lanes – are the lanes drawn as boundaries, and the activities drawn in the same lane as the organization’s activities. Swim lanes must be arranged in a logical order.
    Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
    End or Terminator – is the last phase of the activity. An indicated black circle represents the final node.

  • Step 2: Determine the targeted users

    Second, After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.

  • Step 3: Analyze the activities included

    Third, analyzation is very important in creating an activity diagram. It will help you understand the work of the diagram and avoid unwanted errors.

  • Step 4: Plot the Activity Diagram

    Finally, to plot the activity diagram you will need the users, activities, decisions, and their flows (paths). You will base the flow of activities on the evaluated information to have the exact Activity Diagram.


You need to know the diagrams used to design and develop the Library Management System. This is due to the fact that without it, it is impossible to create a fully functional system.

But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, but you will identify the processes that are required and connect them to the other UML Diagrams.
