Basic Taxonomy

Taxonomy is the practice and science of classification. It is originated from Greek. It uses taxonomic units called taxa ( singular,taxon ). A taxonomy, or taxonomic scheme, is a particular classification , arranged in a hierarchical structure.Typically this is organized by supertype-subtype relationships, also called generalization-specialization relationships, or less formally, parent-child relationships. In such an inheritance relationship, the subtype by definition has the same properties, behaviors, and constraints as the supertype plus one or more additional properties, behaviors, or constraints. For example, car is a subtype of vehicle. So any car is also a vehicle, but not every vehicle is a car. Therefore, a type needs to satisfy more constraints to be a car than to be a vehicle.
