In the field of computer databases, a table is a structure similar to a chart that stores information about a specific subject. It represents a fundamental entity, designating a distinct, identifiable, and definable element, whether concrete or abstract. Often, this entity reflects a real-world element with unique characteristics that distinguish it from others.

The key components of a table include rows, also called records, which represent individual occurrences of the subject. For example, in a table dedicated to “Customers,” each row corresponds to a specific customer. Columns, on the other hand, designate specific fields of information related to the subject. For example, a “Customers” table might include fields such as “Last Name,” “First Name,” “Address,” or “Postal Code.”

An important characteristic is the primary key, a unique column that assigns a unique identifier to each row. Generally, this primary key is an automatically generated number to ensure the uniqueness of the records. Furthermore, each field is associated with a specific data type, such as text, numbers, or dates, ensuring the consistency and integrity of the stored data.

Databases are full of various tables, each dedicated to distinct entities such as “Customers,” “Products,” “Orders,” “Employees,” or “Invoices.” Each table plays a crucial role in organizing and managing data, providing a clear and organized structure for efficient access and easy manipulation of information.
