问题 We're looking for free/cheap or open source UML tools. What tools have you used ? It's OK if there are 2 tools, one each for Flow charts and UML. If a UML tool or Flow Chart tool is cheap(we're a NON-PROFIT), and no open source is good enough, we're open to look at them. Thanks and BR, ~A 回答1: Simple and easy to use: JudeUML. There is a free Community Edition. This software is now released as astah community. 回答2: It's online, but I think yUML is the best free tool I've used. I've used Violet

阅读更多关于 How do I represent a loop in an activity diagram?

问题 I'd like to represent a loop in a UML activity diagram.

Multiplicity vs Cardinality

阅读更多关于 Multiplicity vs Cardinality

问题 When talking about data models and databases, the term Cardinality is often used to describe the number of allowed elements in a given set. UML often refers to the same property as Multiplicity . Is there any differences between these two terms or are they synonymous? 回答1: The simplest explanation would be to say: Multiplicity = Cardinality + Participation Cardinality: Denotes the maximum number of possible relationship occurrences in which a certain entity can participate in (in simple terms

Is TIME an actor in a use case?

阅读更多关于 Is TIME an actor in a use case?

问题 Alright, on a true false question: a)The actors of a system are only represented by humans or another software components. I said TRUE, and the teacher marked it as wrong, not because he considered that I missed hardware components (which I guess I would partially concede), but because, on his words: "TIME is also an actor." How would an use case diagram consider TIME as an actor?? Please refer to any bibliography which considers time an actor. I haven't found any, and truthfully I don't

UML Notation - Aggregations/Compositions vs “Vanilla” Associations

阅读更多关于 UML Notation - Aggregations/Compositions vs “Vanilla” Associations

I've recently spent a good deal of time performing detailed UML designs of various SW components that I have since written. Looking back on what I have recently finished and comparing that to when I first learned UML, I see that I now almost strictly use Aggregation and Composition relationships, and have virtually abandoned "vanilla" non-directed/directed relationships. I still of course use Generalizations and Realizations, but these are distinctly different than those above and are not considered part of this question. It seems to me that Aggregation/Composition implies the same meaning of

self message(non recursive) vs self recursive message

阅读更多关于 self message(non recursive) vs self recursive message

What is the difference of these two messages? I searched the web a bit and most what I could find is A self message is a message that an object sends to itself. It is a message that represents the invocation of message of the same lifeline. A self message can represent a recursive call of an operation, or one method calling another method belonging to the same object. What is the benefit of additional activation bar that recursive message brings? In graphical notation: non recursive self message: recursive self message what is the difference? You should use a self message when you are calling

How to represent a C# property in UML?

阅读更多关于 How to represent a C# property in UML?

Not quite an Attribute, not quite a Method. Stereotypes? <<get>> <<set>> ? I'm retro-modelling an existing system, so I need to clearly reflect that this is not the same as a readonly field or a methods pair (regardless of what the IL says), so I think I'll go with the stereotype, but I'll accept the language independant get_ set_ as a general solution. Thanks all for the sanity test. Properties are just a convenient way of writing get_MyValue() and set_MyValue(value) allowing assignment rather than the normal method calling (using parenthesis). What you are accessing is actually a .NET
