UML&OCL Modeling Languages


Introduction

Objects' types are called classes (i.e. sets of objects as precised in OCL later).


Objects & Classes' diagrams

Nb. The concept of a "Class" comes from set theory and corresponds to "set" of elements sharing common structure/attributes/relations and behavior/operations.

An "association", concept fully developped later, is then similar to a cartesian product,

An "inheritance" to a subset s' inclusion, etc.
