Partial Key:

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

Alternate Key:

All Candidate Keys excluding the Primary Key are known as Alternate Keys.

Artificial Key:

If no obvious key, either stand alone or compound is available, then the last resort is to simply create a key, by assigning a unique number to each record or occurrence. Then this is known as developing an artificial key.

Compound Key:

If no single data element uniquely identifies occurrences within a construct, then combining multiple elements to create a unique identifier for the construct is known as creating a compound key.

Natural Key:

When one of the data elements stored within a construct is utilized as the primary key, then it is called the natural key.

A derived key comes from a sequence. Usually it is used when a concatenated key becomes too cumbersome to use as a foreign key.

When a PC is turned on, it begins carrying out software instructions from its BIOS program. This small program is permanently stored in the ROM BIOS memory IC located on the system board. The information stored in this chip represents all the inherent intelligence that the system has until it can load more information from another source, such as a disk drive or remote server computer.

A transgenic organism is one whose genome has been subject to artificial
modification. A transgenic organism may result when foreign DNA is inserted into
the nucleus of a fertilized embryo. Bacterial transformation is another example of a process that leads to a transgenic organism.
