The ER diagram for the bank management system in DBMS reveals the relationships of the bank management entities within its database.
This describes the logical structure of the system’s database or data storage. To do this, determine the online banking process entities, their properties, and how they interact.
The database design is sketched out using bank management system ER diagrams. This database sketch becomes the system’s data destination and source.

What is Bank Management System?
A bank management system is a way for financial transactions to be done online. In banking systems, people do things by hand. When we use online banking, we use a technique called “virtual machines,” which automates tasks that used to be done by hand.
Bank Management System Database Design
This bank management system er diagram in DBMS was made based on bank requirements. The system can encode customer information. The banking admin can have access to the customer status and information for important transactions. They manage customer and employee files and transactions.
What is an ER Diagram?
In DBMS, the ER Diagram is referred to as the bank management system database design. This ER Diagram is the graphical depiction of relationships between all the entities involved in the system. Its major components are entities, attributes, and relationships.
Importance of ER Diagram
The importance of the ER diagram for a bank’s management system is to help in modeling its data storage or database. It is the basis of the project’s database foundation for construction. This entity relationship diagram (ERD) also aids in defining the data types to be stored, such as their attributes and characteristics.
ER Diagram for Bank Management System
The Bank Management System’s ER Diagram shows entity relationships and their functions.
Based on the image above, the ER diagram for this system is the entity of the bank management system database. Which are presented by tables: customer, employee, reports, transactions, logs, and accounts. These tables meet the system’s requirements and provide more details about each entity.
Bank Management System ER Diagram Tables
These tables below provide the complete database table details such as field names, descriptions, data types, and character lengths. Each of these tables represents the characteristics and attributes of data storage.
Field lists each database’s attributes, description explains each, type lists their data type, and length lists their character lengths.
Table Name: Customer
|customer_ID (PK)||Customer ID||Int||11|
|fname||Customer First Name||Varchar||255|
|lname||Customer Last Name||Varchar||255|
Table Name: Admin
|admin_ID (PK)||Admin ID||Int||11|
|fname||Admin First Name||Varchar||255|
|lname||Admin Last Name||Varchar||255|
Table Name: Employee
|employee_ID (PK)||Employee Id||Int||11|
Table Name: Bank Account
|acc_ID (PK)||Account ID||Int||11|
|customer_ID (FK)||Customer ID||Int||11|
Table Name: Logs
|logs_ID (PK)||Login ID||Int||11|
|trans_ID (FK)||Transaction ID||Int||11|
Table Name: Transactions
|transaction_ID (PK)||Transaction ID||Int||11|
|employee_ID (FK)||Transaction Name||Int||11|
|customer_ID (FK)||Customer ID||Int||11|
Table Name: Reports
|report_ID (PK)||Report ID||Int||11|
|acc_ID (FK)||Account ID||Int||11|
|logs_ID (FK)||Logs ID||Int||11|
The tables given will be the basis for developers on how they will do the bank management system database design. It contains the complete database description and will be entered into the program or data storage as the table names. They will create a database with the attributes given as well as the value of each attribute.

How to create ER Diagram
Time needed: 5 minutes.
Steps in building the ER Diagram for Bank Management System with Cardinality Ratio.
- Step 1: Familiarize 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: 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 is 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: Finalize the entities included
Start designing your ER Diagram by finalizing the entities that must be included in your bank’s management system. You should leave plenty of room for this rectangle in future phases so you can add it to your design.
- Step 3: Add the attributes of each entity
After finalizing the entities, think about the qualities you’ll need to characterize each entity. The details of the various entities outlined in a conceptual ER diagram are supplied as attributes. All of these are examples of attributes. Multivalued attributes can be assigned to several values.
- Step 4: Describe the relationships (cardinality) between entities and attributes
To plot relationships between the ERD you will need the entities, their attributes, and relationships. You will base the data structure from the evaluated information to have the exact Entity Relationship Diagram.
You need to know the diagrams used to design and develop the bank management system. That is to help you create a fully functional system with the use of the ER Diagram. Creating it will help you perceive the back end of the software. This will hold all the data that’ll enter and exit the system.
