Hi,
I wanna ask this :

"Is UML part of SDLC? "

I asked this because All I know was that SDLC is System Development Life Cycle, and in the part of it contain some step that need UML or DFD on it.

But, my lecturer said " UML is not in SDLC, if you use UML you should be use (something I fotgot)."

How's that?

Reason for my vote of 1
Dangerous state of mind. Do you think "SDLC is System Development Life Cycle" is knowledge? It is not, this is only the association between abbreviation and a full name of something, which does not carry any knowledge by itself.

If you going to think at the level of words, you are going nowhere.

Yes, I aware it,
This all because when I were at class, my lecturer gave us book (he's the author) saying SDLC is abbreviation of System Development Life Cycle and ONE of it was Water fall method. And the using DFD to created a class project.
But until now, I've never develop anything using one of them.

So this were we think :

SDLC is parents, DFD is eldest son, UML is \little brother of DFD.

Note : class in this point --> classroom.

No, this is not how it was historically developed, but you can always read about it in Wikipedia. You can easily find the history of these ideas in Wikipedia.

UML is not a part of SDLC.
DSLC is a development strategy for the project from initial requirements gathering to implementation and support.
UML is not a development lifecycle strategy. It is a language that could help you in your development lifecycle.

You can use the SDLC perfectly well without using UML at all.
UML is a modelling language.

In case you want to create class / sequence and other diagrams for your project during the design phase of your project, you can always use UML to create them.

UML can also be useful during the 'analysis' part of SDLC where business analysts can create use cases.

UML can be use with any standard project lifecycle like SDLC, Agile or OOAD.

how abaout DFD with SDLC?

Abhinav S 30-Apr-12 1:53am

DFD or UML can be used in SDLC. It depends on what you are comfortable with.
Both DFD and UML can be used together too - depends on what level of detail you are looking at.

as for SDLC and O2AD.
If I develop project with Microsoft Practices (i don't know if this OOP or anything else) which contain UI, BL, DAL, and Database. Which should I use?

I already aware that DFD focused on "data flow" and UML focused on "activity". So based on that knowing, I wanna ask you, which would you use?DFD or UML to describe your system in order to be tell to user.

ah, another question : which should I use better, UML or DFD? in case I develop software for multiclient usage using VB.net 2010

Invalid question; too bad you don't feel it. Your speculations look like you a falling into a misconception of verbal knowledge not aware of real notions and conceptions behind words.

Of course it is not; I cannot understand where such weird ideas come from; probably from the lack of understanding of either concept.
This is reasonable and sufficient explanation, my 5.
