WebAbstract. Cardinality constraints are one of the most important kinds of constraint in conceptual modeling. In addition to constraining the population of relationship types, … In data modeling, collections of data elements are grouped into "data tables" which contain groups of data field names called "database attributes". Tables are linked by "key fields". A "primary key" assigns a field to its "special order table". For example, the "Doctor Last Name" field might be assigned as a primary key of the Doctor table with all people having same last name organized alphabetically according to the first three letters of their first name. A table can also have a forei…
