A field is a column in a table that contains a specific category of data within a record




How a relational database is organized: Tables of rows and columns Row (record) - example: a person’s address

Column (field) - example: the person’s last name




How various records can be linked: Key field - a field that is used to sort data Primary key - holds a unique value for each record Foreign key - used to cross-reference data among

relational tables
