OCUP 2 Foundation case studies
OCUP 2 Foundation · Put your knowledge to work in context.
The UML 2 Foundation exam, part of the OMG's OCUP2 certification program, is the entry-level credential in a three-exam UML 2 series (Foundation, Intermediate, and Advanced). OMG describes its UML certifications as an industry stamp of approval of an individual's UML modeling and analysis ability, and the Foundation level certifies practitioners whose UML knowledge supports proficient model building and interpretation. The exam tests a subset of the most used UML behavioral and structural diagram types, plus the UML elements and attributes needed to design and implement real, practical, everyday systems. It also covers why certain domains use software modeling and the benefits they derive from it. The OCUP 2 Foundation case studies are 5 cases and about 3,209 words.
