The basic steps are the same regardless of where you’re working. One of the first steps is to determine “what” your system is. A rectangle represents the entity and should have plenty of room. After that, add ovals to represent attributes and connect them with the entity. In the end, leave a space between the rectangle and the oval.
Each of the entities on one ER diagram is known as an attribute. An attribute is a characteristic, trait, or characteristic that an individual entity has. In the case of an ER diagram an inventory Item Name is an attribute that belongs to the inventory of an entity Item. The entity may possess any number of attributes it needs, and each attribute has particular characteristics. For example, a customer’s address may have an address, street number, city, and state. These are all composite attributes which means there aren’t restrictions on the number of each.
The next step to analyze an ER diagram will be to determine how much information each entity contains. The cardinality of every person is the number of factors that exist between two entities. A customer, for instance, might purchase multiple phones using one service for cell phones, while the cell provider maintains numerous phones on the same bill. The ER diagram could make it easier to determine the links between the entities. Furthermore, it could help you determine the information that connects all the entities.

The person on the ER diagram is an adjective. In the same way, the city exists as an instance. So, the connection between two entities is a noun.
The characteristics that make up the ER diagram should be labeled. For example, a teacher entity can have multiple values for a subject. Students may have several subjects. The relationship between two people is illustrated by diamond shapes. Usually, these lines are labeled by verbs. Then, they are identified as entities. If a student is unclear on the meaning of an attribute, the ER diagram can help them understand the relation between two things.
