A key which can not uniquely determine other values

Merging values from tables based on a common attribute

A two dimensional array of data

Supports Select, Product, and Join operations only

Extraction of values from a table

A named column

A concatentation of keys to form a unique identifier

An example is that all field names must be unique

The manner is which specific data is stored

Combines the results of two unrelated queries into a single output

Supports all algebraic operations as well as entity and referential integrity

A DBMS Approach that manages data as a collection of tables

A column in a relational table

Knowing the value of one key means you know the others

Only common values from related tables are included

An example is that a foreign key must have a valid entry in the referring table

Either a composite key of primary key

A key or combination of keys that may become a unique identifier

Supports all algebraic operations but not entity and referential integrity

The union of all possible combinations of table elements

When every nonkey is dependent upon a unique identifier

An entity instance

An example is that primary keys can not be null

A unique record identifier

A key which is used to relate tables together

Anything about which we wish to keep information
