The UML Notation

Just as detail-level business architectural modeling involves first creating views derived from high-level architecture frameworks, detail-level technical architecture modeling involves first creating views derived from technical architecture frameworks. There may be various types of diagrams within each view and an associated visual notation for representing these individual diagrams.

Just as Enterprise Architects have standardized on BPMN for capturing and representing detail-level business architecture, so have they standardized on UML as the visual modeling notation for capturing and representing detail-level technical architecture. UML has also been evolving for many years and has led to several specification updates from 1.x to 2.x versions.

For this Discussion, identify one significant difference between UML 1.x and 2.x, and answer each of the following questions:

1. How does this difference affect the use of the notation?
2. What are the benefits and drawbacks to this change?
3. Does this feature affect the user’s dependence on modeling tools? Explain your reasoning.

Be sure to defend and support your opinion, and remember to properly cite your sources according to APA guidelines.
