Final answer:
A Database attribute includes a name, datatype, and atomic value, where the name is an identifier, the datatype defines the kind of data, and atomic value implies indivisibility in the relational model.
Step-by-step explanation:
The element that has three parts: name, datatype, and atomic value is typically referred to as a Database attribute. In the context of databases:
- A name identifies the attribute within its table.
- A datatype specifies what kind of data the attribute represents (such as integer, string, date, etc.).
- An atomic value means that the value is indivisible as far as the relational model is concerned.
These attributes are the building blocks of a Database schema, which defines the structure of the database and how data is organized. Database tuple, commonly known as a row, contains an instance of data for each attribute. The collection of tuples makes up a Database instance, representing the data stored in a database at a particular moment in time.
