Answer 2

Subcategories of Attribute analysis are​?

Attribute has 6 subcategories which are as follows...

• Simple attribute
• Composite attribute
• Single-valued attribute
• Multi-valued attribute
• Derived attribute
• Complex attribute

Explanation:

Attribute refers to the quality or characteristic of an entity. An entity can have multiple types of properties. In all these properties, any one property is considered as a primary key, it is called an attribute.

For example, a student in a school database has attributes such as his name, his age, his roll number, etc. Here his/her roll number will be used as the primary key. A name can belong to more than one student. There can also be equality in age, but the roll number is not repeated. It is special to that student and has a unique identity.
