Data design can incorporate supertype and subtype tables in the document. In the flow chart, the organization will determine the order and usefulness of each type.
it just separates the sub type and supertype entity
In database design, a subtype is a specialized entity that inherits attributes and relationships from a higher-level entity called a supertype. Subtypes represent specific categories or types within a broader classification. The attributes and relationships unique to each subtype are represented in addition to those inherited from the supertype.
Completeness Constraint. * The Completeness Constraint addresses the issue of whether or not an occurrence of a Supertype must also have a corresponding Subtype occurrence. * The Total Specialization Rule specifies that this is the case. This is diagrammed with a double line from the Supertype to the circle as shown here. * The Partial Specialization Rule is the one we have followed thus far in the notes (single line to the circle) -- no such constraint exists. You can have a Supertype named VEHICLE and a Subtype named AUTO, but an occurrence of a vehicle need not be an automobile.
Taxonomy is the practice and science of classification. The word comes from the Greek τάξις, taxis (meaning 'order') and νόμος, nomos ('law' or 'science'). Taxonomies, or taxonomic schemes, are composed of taxonomic units known as taxa (singular taxon), or kinds of things that are arranged frequently in a hierarchical structure. Typically they are related by subtype-supertype relationships, also called parent-child relationships. In such a subtype-supertype relationship the subtype kind of thing has by definition the same constraints as the supertype kind of thing plus one or more additional 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 thing needs to satisfy more constraints to be a car than to be a vehicle.
Taxonomy(from Ancient Greek: τάξις taxis "arrangement" and Ancient Greek: νομία nomia "method"[1]) is the practice and science ofclassification or the result of it. Taxonomy uses taxonomic units, known as taxa(singular taxon). A resulting taxonomy, a taxonomy, or taxonomic scheme, is a particular classification ("the taxonomy of ..."), arranged in a hierarchical structure or classification scheme. Typically this is organized by supertype-subtype relationships, also called generalization-specialization relationships, or less formally, parent-child relationships, typically indicated by the phrase 'is a kind of' or 'is a subtype of'. In such an inheritance relationship, the subtype by definition has the same properties, behaviours, and constraints as the supertype plus one or more additional properties, behaviours, or constraints. For example: a bicycle is a kind of vehicle, so any bicycle is also a vehicle, but not every vehicle is a bicycle. Therefore a subtype needs to satisfy more constraints than its supertype. Thus to be a bicycle is more constraint than to be a vehicle. If other kinds of relationships between concepts are also included, a taxonomy is extended into an ontology. Thus various ontologies also include a taxonomy. This holds especially for the upper level ontologies (arrangements of generic concepts).
It is not a Tuner monster - Tuner is a monster subtype and will be displayed with the monster's type (Dragon/Warrior, etc) and supertype (Effect/Normal, etc). It is not enough just for it to have Tuner in its name, that is not the definition of a Tuner monster. You are free to use Powered Tuner as a Synchro component, but only as a non-Tuner monster.
