Fields in a Relational Schema
In a relational schema, each tuple is divided into fields. These fields are also known as attributes or columns in a database table. Each field represents a specific piece of information about the entity being stored in the database.
Domains
Domains are the set of possible values that a field can take. They define the type of data that can be stored in each field. For example, a field for a person's age may have a domain of integers between 0 and 150. Domains help ensure data integrity by restricting the type of values that can be stored in a field.
Division of Tuples
When a tuple is divided into fields, each field corresponds to a specific attribute of the entity being represented. For example, in a table storing information about students, fields may include student ID, name, age, and grade. Each field holds a single piece of data related to the entity.
Importance of Fields
Fields play a crucial role in organizing and structuring data in a relational database. They allow for efficient storage and retrieval of information, as well as enforcing data consistency and integrity. By dividing tuples into fields, databases can store and manage large amounts of data in a structured and organized manner.
