Explanation
Data modeling is the process of creating a blueprint for a database. The ingredients or components of data modeling include:Entities/Objects: Entities represent the real-world things you want to store information about in your database. For example, in a library database, an entity could be "Book" or "Author".Attributes: Attributes are the specific characteristics or properties of an entity. Going back to the library example, some attributes of the "Book" entity could be "title," "author," and "ISBN."Relationships: Relationships define the connections between entities. In the library example, there could be a relationship between "Book" and "Author" that shows which books were written by which authors.All three of these components are essential for building a comprehensive data model.
