In life, the majority of our relationships are given to us by birth, there are only a few friends that we have the freedom to consciously choose.
In the business world, however, relationships are more transactional and goal-oriented. With technology, every business activity is comparable to a database, where relationships are geared to business ends. The more these relationships are fleshed out, the better is the result. It is at this stage that businesses find wide applicability of the Entity Relationship Diagram (ERD) concept.

FAQs on Entity Relationship Diagrams
What is an Entity Relationship Diagram?
Entity Relationships diagrams explain the logical structure of any database through a flowchart. These depict the graphical representation of entities and their relationships in any industry. ER diagrams include three things, entities, attributes, and relationships. An entity is an object or concept that is used to store data. Through relationships, the entities share the data between them. Different kinds of symbols are used to illustrate entities, attributes, and relationships. Ovals are used for attributes, rectangles are used for entities, and diamonds are used for relationships.
Why do you need to draw Entity Relationship Diagrams (ERD)?
When you want to make database applications impactful or to define role naming in the company, then you need an ER diagram. These diagrams are essential to design the company database as it is a must to get a clear picture of all entities, attributes, and their relationships. Â The major reasons ERD exists are:
- It is helpful in creating logical views of the database
- It handles versions of designs
- It visualizes data movement between different data assets
- It helps in collaborating with business processes and strategies
- It establishes good communication between business and technical stakeholders
- It centralizes governance of company data and information
Describe the basic components of an ER Diagram in detail?
We know that the main components of ER diagrams are Entities, Attributes, and their Relationships. Entities can be described as objects or concepts that gather information and are often represented as nouns. Attributes give information about a unique character of an entity. Relationships showcase how two entities are related to each other and are labeled as verbs.
How do you determine an Entity Relationship Diagram?
ER Diagram is a data model tool that gives you access to a vast range of enterprise-level capabilities, industry-leading responsibilities, data platform support, flow modeling, visual data lineage, business data objects, and business intelligence. Besides this, ERD forms a framework for creating new databases and modifying existing databases. Your company’s designers can use these diagrams to communicate with customers, developers, programmers, and end-users.
Additionally, ERD is easily transformed into relational tables to make databases, and data can be retrieved efficiently with a primary key and foreign key. These diagrams are used to describe operations and relationships within a company.
What kinds of symbols are used to make ER diagram?
There are many symbols like diamonds, rectangles, ovals, arrows, and connecting lines that are used to design and understand ERDs. Entities are represented with rectangles, attributes are represented with ovals, and relationships are represented with a diamond. The arrow symbol shows cardinality or transfers data from an entity whereas the connecting line symbol is used to visualize the attribute’s connection between entities and relationships.
What are the attributes in ER diagram?
Attributes are used to define the characteristics or properties of the entities. An entity may contain one, two, or more attributes. Numerous kinds of attributes are used in ER diagrams:
- Simple Attribute
This kind of attribute cannot be split into components, such as student IT, employee ID, product ID, department ID, etc.
- Composite Attribute
Unlike simple attributes, a composite attribute can be divided into components. Like an address that can be split into a house or flat number, street or society name, city, district, state, pin code, etc.
- Single-Valued Attribute
This occurs when an entity holds only one value. For example, an employee’s age, student’s age, etc.
- Multi-Valued Attribute
A multi-valued attribute contains more than one value for each entity. For example, contact details of employee – mobile number and landline number, etc.
- Derived Attribute
When you want to derive the data from other attributes then you use derived attributes. For example, annual and monthly salary of an employee.
- Complex Attribute
Nesting of multi-valued and composite attributes creates complex attributes. This kind of attribute is seldom used in Database Management Systems.
