    Glossary

    A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

    Alternate (candidate) Key
    A column or combination of columns, other than the primary key column(s), which may be used to uniquely identify a row in a table. The primary key is chosen from one of the candidate keys. As you can read from the article behind this term; if you have many candidate keys, you have a problem of selecting the best fit.

    Attribute
    An attribute is a part of the description of the entity. The entity itself is described by one or more attributes; together, they describe all things of importance about the entity. Example: Typhical attributes for a customer would be name, address, telephone, etc.
