The proximal row of carpal bones moving from radial to ulnar are the scaphoid lunate triquetrum and. Redundancy in relation may cause insertion deletion and update anomalies.

These anomalies affect the process of inserting deleting and modifying data in the relations. This is still a weak design introducing unnecessary duplication and what is called data insertion anomalies which means that it could contribute to inconsistent data. Prerequisite Database normalization and functional dependency concept.

The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. Such figures may be easily caused accidentally. So it helps to minimize the redundancy in relations.

Retroviral insertion in the proximity of the LMO2 gene leads to aberrant transcription and expression of LMO2. Update anomalies which are classified as insertion deletion or modification anomalies. There are two main types of insertion anomalies which we illustrate using this table.
