What is cloning in database?

Database cloning is the process of creating a point-in-time copy of a production database or its backup set. Cloned databases can be used for multiple purposes: During application development cycles for testing functionality that has to be implemented using the current database structure and content.

How can cloning be used?

Therapeutic cloning involves creating a cloned embryo for the sole purpose of producing embryonic stem cells with the same DNA as the donor cell. These stem cells can be used in experiments aimed at understanding disease and developing new treatments for disease.

What two methods can achieve cloning?

Many people first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Artificial cloning technologies have been around for much longer than Dolly, though. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.

Does cloning require fertilization?

Absolutely not. Despite science fiction books and movies, clones are born just like any other animal. The only difference is that clones don’t require a sperm and egg to come together to make an embryo.

Where does cloning come from?

As cells grow and divide, they naturally create clones using cellular division, a process called mitosis. The cells use proteins and enzymes coded in their genes to copy their genetic material.

Why do we need to clone databases?

DBA’s occasionally need to clone databases to test backup and recovery strategies or export a table that was dropped from the production database and import it back into the production databases. Cloning can be done on a different host or on the same host even it is different from standby database.

What is the purpose of the DBCC clonedatabase?

The new database generated from DBCC CLONEDATABASE is primarily intended for troubleshooting and diagnostic purposes. In order for the cloned database to be supported for use as a production database, the VERIFY_CLONEDB option must be used. All files in the target database will inherit the size and growth settings from the model database.

How are genes cloned for genetic research?

Researchers routinely use cloning techniques to make copies of genes that they wish to study. The procedure consists of inserting a gene from one organism, often referred to as “foreign DNA,” into the genetic material of a carrier called a vector.
