3Introduction to UMLHue UniversityCS 578 Software Architecture -- From Architecture to Design: Role Of UML12 September 2009 2001-3 Neno Medvidovic & Edward Colbert3Walk the audience through the timeline. Point out that the UML is the natural successor to the notations.1. Late 80s and early 90 - there are many (50+) OO methodologies2. Among the first generation methodologies, Booch and OMT stood out3. Around 1993, second generation methodologies came out - Booch 93 and OMT-II. Methodologist borrowed good concepts from each others so many concepts were the same across the methodologies, but different notations.4. Oct. 1994 - Dr. James Rumbaugh joined Rational to unify Booch & OMT. 5. At OOPSLA 95, Grady and Jim announced Unified Method 0.8.6. Use Case technique developed by Dr. Ivar Jacobson was adapted by all methodologies by then.7. Rational acquires Objectory in fall of 95 - Dr. Ivar Jaconson joins Rational.8. Jun of 96 - Rational submits UML 0.9 to OMG.9. UML gains industry support from HP, Microsoft, Oracle + 16 others10. UML is the de facto standard for OO and component technologies11. The final submission goes in Sep. 97 - expect the announcement in Dec....UML l g?N l mt ngn ng m hnh ha, khng phi l mt phng phpMt phng php thng thng bao gm mt tp cc quy tc, mt ngn ng m hnh ha v mt quy trnh m t nhng cng vic cn lmMt ngn ng m hnh ha bao gm cc k hiu v cc cch thc s dng cho vic thit kQuy trnh l nhng s hng dn cc bc trong qu trnh thit kNgn ng m hnh ha l thnh phn quan trng nht trong mt phng php, l yu t kt ni gia cc thnh phn4Introduction to UMLHue UniversityTi sao li s dng UML?Gip cho vic phn tch v thit kL cng c giao tip (Communication)S dng cc u im ca OOTi liu ha (Documentation)
