Key Field: Database, Abstract Syntax Notation One, Binary Format Description Language, CODASYL - Brossura
Sinossi
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. A key field is a field or set of fields (a key is then said to be a composite key) of a database (typically a relational database) table which together form a unique identifier for a database record (a table entry). The aggregate of these fields is usually referred to simply as "the key". Key fields also define searches. Relational databases enforce referential integrity of their tables by matching primary keys with foreign keys. Keys can also be distinguished in technical keys (also known as surrogate keys) and business keys (also known as natural keys or domain keys).
