A table in a database is a structured arrangement of data organized into rows and columns, forming a grid. Each row represents a single record, while each column represents a specific field or attribute of the data1. Tables are fundamental components of relational databases, enabling efficient data storage, retrieval, and manipulation.
Components of a Table
Columns
Columns, also known as fields or attributes, represent the vertical divisions in a table. Each column has a unique name and a specific data type that defines the kind of data it can store. For example, a column named FirstName might store string values representing individuals' first names2.
Rows
Rows, also known as records or tuples, represent the horizontal divisions in a table. Each row contains a unique set of data for each column, forming a complete record. For instance, a row might contain the first name, last name, age, and address of a person2.
