UML Concept Drawings

tsinc80697 · 3 Jan 2008 at 16:34

I have to do one of these for Uni but I have been taught / told absolutely nothing about them(Its for a ASP.net web application)

i have a case study which shows a Logical design of the database and several tasks I have to do for the UML conceptual drawings.

My friend has told me a bit about them but he's as confused as I am about them all. He said he had looked on a few websites but the tutor has been showing us different drawings to what can be found on the web, I assume there are multiple ways to do it?

just wondering if anyone has done them before, has any advice and websites that might help me understand everything? I was told dependencies and multiplicities can be hard to understand?

Thanks

Well UML is a vast topic.

There are many different types of diagrams that make up UML. Popular ones I did at Uni were:

A Class Diagram will probably be your best bet for databases.
Use Case Diagram, used to show the functionality of a system.
And a Sequence diagram.

The above should help.

Thanks.

Ill have a google of those things then and post back here if I get stuck!

Also been given the use case diagram!

Extract from the PDF :

" The application must be web based and accessible to students over the Internet, allowing
them to easily sort out their timetable before the start of term. The application must also
allow academic staff to book additional equipment that they may need for specific teaching
sessions. The requirements were documented as use cases. The use case diagram (Illustration
B.1) provides an overview of who uses the system, and how they expect to use it. The use
case specifications give further details of the expected behaviour. Together, they form the
formal definition of user requirements for the Staff Directory web-database application"

Start with a Class Diagram.

They should really let you know exactly what they require, UML is such a big topic.

Argh, UML is awful and seemingly open to many interpretations. How many different ways can you write a program? Lots. Therefore there's lots of ways of showing that

Agile all the way.

Ah sounds great then :/
Liked PHP but not keen on ASP.Net as its more programming than web developing to me.

Definitely not liking this UML malarky though, confusing what I am meant to do, thats before I even start thinking about how to do!

Hate it too, sounds like we are doing similar courses.

Like the rest of them its just this pointless one, didn't know it would be like this otherwise I would have chosen a different one!
