How to create an Entity-Relationship (ER) Diagram

Time needed: 5 minutes

Here are the steps on how to build Payroll Management System ER Diagram with Cardinality Ratio.

  • Step 1: Become acquainted with the ER Diagram (Entity Relationship Diagram). Symbols and Cardinality

    The Entity Relationship Diagram shows the structure of data types in a project. It uses symbols to clarify its parts and relationships. Their symbols and applications must be familiar before you build the ER Diagram.

    ER Diagram Symbols:
    Fields are the parts of a table that define the entity’s characteristics. In the database that the ERD models, attributes are commonly thought of as rows. 

    Keys are a technique to categorize data quality. It is used to organize ER diagrams and assist users in modeling their databases to ensure that they are efficient. This is also used to connect different tables in a database. 

    A primary key identifies a single entity instance, which means a unique attribute or set of attributes. 
    A foreign key is produced when data attributes have one too many relationships with other entities.

  • Step 2: Complete the entities that will be included.

    Begin designing your ER Diagram by finalizing your railway reservation system’s entities. These are rectangles. You must leave room in future phases so they can be incorporated.

  • Step 3: Add the attributes of each entity

    Upon finalizing the entities, analyze their attributes. As characteristics, ER diagram entities are described. All these are characteristics. Multivalued characteristics have several values.

  • Step 4: Describe the relationships (cardinality) between entities and attributes

    Entities, characteristics, and relationships are needed to draw ERD relationships. The data structure and entity relationship diagram are based on evaluated information.


The Payroll Management System was designed and built with the help of several diagrams, including the ER (entity-relationship) diagram. Each diagram you make and design will help you explain your ideas and show off your skills.
