Final answer:
The question deals with retrieving information from database tables using referenced fields, typically through SQL queries. Reference fields, like primary and foreign keys, are crucial for linking records across different tables in a relational database system.
Step-by-step explanation:
The concept described in the question refers to the process of retrieving information from databases using referenced fields. This is a fundamental aspect of database management and is commonly executed through Structured Query Language (SQL), which is a standardized language for managing and manipulating databases. To get information from tables, specific SQL statements like SELECT queries are used. These queries can leverage primary keys, which are unique identifiers for records in a table, to access related information in other tables through foreign keys.
For example, if you have a 'Customers' table and an 'Orders' table in a database, and each order is linked to a customer through a customer_id, you can use this referenced field to retrieve all orders for a specific customer. References such as these are also a principle behind the relational database model, which organizes data into one or more tables (relations) of columns and rows, with a unique key identifying each row.
