Library Management System database design

This page provides material on the architecture of the Library Management System database. The database, in turn, is further explained in-depth with all fields used for data types, limitations available, primary key, and foreign key.

What is a database management system :

The database architecture is used to handle a vast volume of information. The database is a list of information that is uniformly placed in rows and columns in tables. The database table has a special name that describes its contents. In this database, we define the 4 tables available in the program that is used to store all information.

Data types and its description:

The data form fields in the database table used in the database table are explained below.

  1. Integer: one optional character (+ or-) followed by at least one digit (0-9). Leading and trailing blanks would be overlooked. There is no other character permitted.
  2. Varchar: This is used to store alphanumeric characters. In this data type, the maximum number of characters up to 8000 ranges can be set by default as the size of the SQL server is set to 50 character range.
  3. Date/Time: The date/Time data form is used to represent the date or time.

Entity Relationship Diagram:

In contemporary database information engineering, Object Relationship Diagram is used to explain the conceptual structure of the database. It is a relational schema database simulation approach that is used

Modeling the method and the solution. This technique is widely used in the architecture of databases. The diagram generated using this approach is called the ER diagram.

The ER-diagram illustrates the separate relationships between entities, treating each object as an individual. An entity is represented as a rectangular shape and a partnership is represented as a diamond shape. It shows the relationship with the data object. The ER-diagram is a notation used to perform the task of data modeling.

Entity: Entity is the kind of thing we want to store knowledge. It is a fundamental building block for preserving knowledge about the market process. An individual is an object specified in the information system that you choose to store information about. Entities are different things in an organization.

Relationship: A relationship is a natural link or affiliation between entities used to refer to two or more entities with certain similar characteristics or a substantive contact between the entity.

Attributes: Attributes are the characteristics of the object and the entity’s association descriptor. Attributes are elementary bits of knowledge that are connected to an individual.

    Here’s example code to create the tables using SQL (including MySQL):
    CREATE TABLE bookdetails (
    Accno VARCHAR(50) NOT NULL PRIMARY KEY,
    Author VARCHAR(50) NOT NULL,

    No_of_copies INT NOT NULL,

    Price DECIMAL(18,2) NOT NULL,
    Status VARCHAR(50) NOT NULL
    ) DEFAULT CHARACTER SET utf8;

    I suggest looking at the MySQL Reference Manual for more information:
