The loan management system ER diagrams shows the relationships of the loan management entities within its database. This describes the logical structure of the system’s database or data storage. It is done by identifying the loan management process entities, their properties, and the interactions between them.
The database design is sketched out using loan management system ER diagrams. This database sketch becomes the actual basis of the system’s data storage that will serve as data destination and source.

What is Loan Management System?
The entire loan lifecycle is automated via an online loan management system. Lenders might use it for the entire process or just certain sections of it. The system provides assistance at every level, from processing new customer information to collection management.
What is an ER Diagram?
Entity Relationship Diagrams (ER Diagrams) depict how “entities” in a system relate to each other. ER Diagrams are used to construct or fix relational databases in software engineering, BIS, teaching, and research.
ERDs or ER Models use rectangles, diamonds, ovals, and connecting lines to depict how entities, relationships, and attributes are related. Entities are nouns and relationships are verbs, just like in real language.
Importance of ER Diagram
Entity relationship diagrams are a visual way to start designing a database. They can also be used to help figure out what an organization’s information system needs are.

The tables given will be the basis for developers on how would they do the loan management system database design. It has the complete description of the database and they will put this into the program or data storage the same as the names given to each of the tables. They will create a database with the attributes given as well as the value of each attribute.

Steps in building the ER Diagram for Loan Management System with Cardinality Ratio.
- Step 1: Familiarize the ER Diagram (Entity Relationship Diagram) Symbols and Cardinality
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 familiarized before you build the ER Diagram.
ER Diagram Symbols:
• Field – 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 qualities. 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.
– Primary Key: identifies a single entity instance which means a unique attribute or set of attributes.
– 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 loan 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. Characteristics of an entity, a many-to-many relationship, or a one-to-one relationship are all 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.
Conclusion:
You need to know the diagrams used to design and develop the Loan Management System. That is to help you create a fully-functional system with the use of 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.
