Additionally, the structure, content, and relationships of the data stored in each table are unique and specific to the type of information being stored. Constraints and indexes can also provide uniqueness within a table.
A common field in a database is the "primary key". It is a unique identifier for each record in a database table and is used to uniquely identify each row. It is typically a numerical value or a combination of values that ensures each record is distinct from all others.
A database field name is a unique identifier for a particular piece of data within a database table. It helps to organize and distinguish different types of information stored in the database. Each field name typically corresponds to a specific attribute or characteristic of the data being stored.
