An entity-relationship diagram (ERD) is a data modeling technique that graphically illustrates an
information system's entities and the relationships between those entities.
An ERD is a conceptual
and representational model of data used to represent the entity framework
infrastructure.
Cardinality refers to the uniqueness of data values contained in a
column. High cardinality means
that the column contains a large percentage of totally unique values. Low cardinality means that the column
contains a lot of “repeats” in its data range.
Degree is defined as the degree of a relationship type concerns the number of entities
within each entity type that can be linked by a given relationship type.
