1 primary key
"One or more fields that uniquely identify each record in a table. In the same way that a license plate number identifies a car, the primary key uniquely identifies a record." -
2 primary key
A candidate key that is selected to be the principle identifier for uniquely identifying records in a database table. -
3 primary table
"The ""one"" side of two related tables in a one-to-many relationship. A primary table should have a primary key and each record should be unique." -
4 key
"A column or group of columns that uniquely identifies a row (primary key), defines the relationship between two tables (foreign key), or is used to build an index." -
5 foreign key
"A key in a database table that comes from another table (also know as the ""referenced table"") and whose values match the primary key (PK) or unique key in the referenced table." -
6 referencing key
"A key in a database table that comes from another table (also know as the ""referenced table"") and whose values match the primary key (PK) or unique key in the referenced table." -
7 alternate key
A candidate key that is not designated as the primary key and is used to uniquely identify records in a database table. -
8 foreign key
A set of fields whose values are migrated from a primary key or an alternate key from a parent table. -
9 natural key
A primary key or alternate key whose values identify objects in the real world. -
10 color key
"A color used for transparent or translucent effects. An overlay surface is displayed in the region of the primary surface that contains the color key. In video production, color keys are used to combine two video signals." -
11 FK
"A key in a database table that comes from another table (also know as the ""referenced table"") and whose values match the primary key (PK) or unique key in the referenced table."FK -
12 one-to-many relationship
An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of many records in the related table. -
13 one-to-one relationship
"An association between two tables in which the primary key value of each record in the primary table corresponds to the value in the matching field or fields of one, and only one, record in the related table." -

"An approach to public key cryptography based on properties of elliptic curves. The primary advantage of ECC is efficiency, which becomes important as devices get smaller and security requirements get more demanding. For example, ECC keys between 163 bits and 512 bits are one-sixth to one-thirtieth the size of equivalent security-level RSA keys. As key size increases the relative efficiency of ECC increases." -
