Library Management System Sequence Diagram | UML

Library Management System Sequence Diagram

LIBRARY MANAGEMENT SYSTEM SEQUENCE DIAGRAM is created with the Unified Modeling Language (UML) that depicts the flow of messages between objects in a scene. It is made up of objects connected by lifelines as well as the messages they exchange overtime during the interaction.

The Sequence Diagram for Library Management System represents the scenario and the messages that must be passed between objects. This is done for the scenario’s functionality to be realized. It’s an interaction diagram that shows how activities are carried out, including when and how messages are sent.

Importance of Library Management System Sequence Diagram

The importance of Library Management 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 Library Management 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 Library Management System

The UML Sequence Diagram for Library Management System is one of the methods used for project development. It is a useful tool for documenting the Library Management 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.

Users of College Library Management System Sequence Diagram

The users of the College Library Management System Sequence Diagram are the following:

  • School Librarian : The school librarians will be the ones to use the system most of the time. They will monitor the books from time to time and will cater to the borrowing and returning of books. They were also responsible for all the activities related to the library.
  • Book Borrowers : Book borrowers were not just the students but also the professors or instructors. They will also have access to the system and to do that, they will have to log into the system. This will help the librarian and the admin monitor the book borrowers.
  • School Admin : The Library Management System can be a stand-alone project or a part of a bigger project. Nevertheless, it always has the admin which can access all of the library information. This is done when there are serious scenarios or problems.

Library Management System Sequence Diagram with Explanation

The Library Management System Sequence Diagram with Explanation is given to expound its ideas. This sequence diagram is shown and is based on the concept of Library Management.

The diagram shows the series of messages that occurred to complete the task of managing Library. The diagram portrays a single scenario which is very common for library management system. 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 student, library server (computer), account database, and book database. These objects were based on practical activities that happen in library management. 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.

Time needed: 5 minutes.

Steps in creating a Sequence Diagram for Library Management 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 Library Management 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 in library management. 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.

Conclusion:

You need to know the diagrams used to design and develop the Library Management System. 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 a sequence diagram, which describes the flow from one object to another. By completing the Sequence Diagrams per module or per process, you will easily achieve your desired system. Check out our Related and Recommended Articles for more Learnings and Information.
