Overview: UML® (Unified Modeling Language™) and SysML® (Systems Modeling Language™)

This presentation will provide an overview of both UML (Unified Modeling Language) and SysML (Systems Modeling Language) and demonstrate how they are successfully applied in practice. You will also learn about the exciting work going on as these standards continue to evolve, including the expanding suite of standards defining precise, executable semantics for UML and SysML and the broad industry effort ongoing to develop SysML v2. Presentation recorded in Ottawa, Canada September 2018.

Presenter: Ed Seidewitz, CTO, Model Driven Solutions, co-chair of OMG fUML, Alf and PSCS RTFs, and Model Interchange SIG

for me this is one of the best introductions into UML and SysML -!!

[informatik]

Very informative.
This lecture allowed me to look at UML under different angle and now UML looks to me quite attractive and (what is the most important) *practical* 👍

[RichardWheeler-SE-BA-PM]

This was very, very helpful. It looks like I'll have to look for the rest of the video on the OMG website because the full version still hasn't replaced the truncated version here. I see that I'll need more than an overview to start using UML or SysML, anyway.
Judging by the terminology used, the audience comprised software folks because definitions of UML terms depended on understanding OOP terms. For example, the section on Class Diagrams used OOP terms to define UML terms. For systems engineers who aren't programmers, the boutique terminology is ambiguous and confusing. The implication that I need to study OOP in order to understand UML and study UML in order to understand SysML is very discouraging.

very informative and easy to understand video

I'm trying to sunset quite a large framework, this will be helpful

[mervenlbnt]

is there any source that we can reach this slide?

19:32 Class Diagram: Order Information Model

[JarekZelinski]

I see some logic fails, e.g. including UC as a nonworking part, why does the author connect this to the actor? In UML we can read UC model is not an internal structure, why author show internal parts of the code (extends, include)?? and so on...

[susabara]

uml --- the language that has no machine- and human readable text form. no, the xml serialization of uml models is _not_ human-readable...

and the specification that is deliberately underspecified and _needs_ specialization (to SysML or AUTOSAR or whathaveyou) --- which in theory are free to redefine everything if they deem it necessary.

So to understand one of the derivatives, you need to dig through the UML, then the derivative and then revisit UML again for the fine print.

that said, uml has a few very clever concepts, like redefining and splitting attributes on refinement, and partial diagrams, the unification of which gives the complete picture.

I think it took a very wrong turn when it thought drawing diagrams was the future of construction and implementation of software systems.

[JarekZelinski]

OMG have BPMN for business process modelling, now UML prepares activity diagrams for algorithms (methods) not for business processes...

[philwilkinson]

Any answer on the second part? It is a great introduction to sysml by the way

[francescobenacci]

The video isn't complete. Is the 2nd part provided?

[JarekZelinski]

Class diagram as a database? Again? Mixing domain model (namespace) with code architecture? Again? Hm...

[yoyoyodaboy]

As a student who doesn't yet have any experience in professional software development, I found this lecture inaccessible.

If I could better see the slide when the camera is zoomed out, then it might have been slightly easier to grasp. Then again, the benefit of that could well be trivial anyway.

Please pardon my frustration. I was assigned this video by my professor and am annoyed to have no idea what he expects me to take away from it.

I dig the cringe jokes - too bad the audience was too stuffy to yield to the hilarity.
