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.<\/p>\n\n\n\n
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.”<\/p>\n\n\n\n
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.<\/p>\n\n\n\n
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.<\/p>\n","protected":false},"template":"","categories-glossary":[313],"class_list":["post-164050","dictionnaire-dico","type-dictionnaire-dico","status-publish","hentry","categories-glossary-data-analytics-marketing-intelligence"],"_links":{"self":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/dictionnaire-dico\/164050","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/dictionnaire-dico"}],"about":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/types\/dictionnaire-dico"}],"wp:attachment":[{"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/media?parent=164050"}],"wp:term":[{"taxonomy":"categories-glossary","embeddable":true,"href":"https:\/\/digitionary.com\/en\/wp-json\/wp\/v2\/categories-glossary?post=164050"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
