The correct answer is C. Relationship.
A database is a collection of data that is organized so that it can be easily accessed, managed, and updated. The data in a database is typically stored in tables, which are made up of rows and columns. Each row in a table represents a single record, and each column represents a single attribute of that record.
A relationship is an association between two or more tables in a database. Relationships are used to model the real-world connections between entities. For example, a relationship between a “Customer” table and an “Order” table would represent the fact that customers can place orders.
While relationships are an important part of database design, they are not essential. A database can be created without any relationships, and it can still be used to store and manage data. Therefore, the term “relationship” is the least related to database among the given options.
Here is a brief explanation of each option:
- Attributes: An attribute is a characteristic of an entity. For example, the “Customer” table might have attributes such as “Name”, “Address”, and “Phone Number”.
- Tuples: A tuple is a row in a table. Each tuple represents a single record in the database.
- Columns: A column is a vertical row in a table. Each column represents a single attribute of a record.
