UML stands for Unified Modelling Language. ER Diagram stands for Entity Relationship Diagram. It is a general modelling language which is used to visualize the design of a software system. It is a pictorial representation of the real-world entities and their relationships with each other.
How can ER diagram be reduced?
The database can be represented using the notations, and these notations can be reduced to a collection of tables. In the database, every entity set or relationship set can be represented in tabular form.

With their enhanced features, you can plan databases more thoroughly by delving into the properties and constraints with more precision.
