Discuss the difference between a composite key and a composite attribute.How would each be indicated in an ERD?
Attribute is the property of entity.The composite attribute is like address(where street no,house no,town name all include).Composite key is also an attribute,but only which attribute are work as a unique identifier. Example:> In an ERD if vendor placed with orders then order(order day, order number) vendor(vendor code,vendor address) Here, order and vendor both are entity and order number, vendor code both are Composite key(because those are unique)but vendor address is a Composite attribute and order day(may be not unique)is an attribute only. So, we can conclude that all attribute not Composite key.
What is a Composite attribute relating to database?
A composite attribute in a database is an attribute that can be divided into smaller sub-parts, each representing a distinct property. Instead of storing it as a single value, a composite attribute is broken down into its components to improve data organization and accuracy. This approach helps in reducing redundancy and ensures data integrity within the database.

What is example of partial dependency?
Partial dependency occurs in a database when a non-prime attribute is dependent on only a part of a composite primary key, rather than on the whole key. For example, in a table with a composite primary key consisting of StudentID and CourseID, if the attribute InstructorName is dependent only on CourseID, then this is a partial dependency. It indicates that the design can be improved by normalizing the database to eliminate such dependencies.
