1. Introduction

This is an Engineering ER Diagram. Here is your first choice for the engineering team to visualize and understand the systems and projects. You can simplify the engineers' workflow by creating project visuals. For example, using an ER diagram to analyze the database, a P&ID for process design, and a PERT chart for project management.

2. What is ER Diagram

Entity Relationship Diagram (ERD) or Entity Relationship Diagram (ERD) is a diagram that shows the relationship between entity sets contained in a database. In other words, ER diagrams aid in the explanation of database logical structure. Entities, attributes, and relationships are the three main notions that ER diagrams are built on.

Rectangles are used to represent entities, ovals are used to describe characteristics, and diamond shapes are used to show relationships in ER Diagrams.
