Understanding the WSDL File

-

Due to the maturity of Web Services toolkits, many developers do not make the effort to understand and interpret the WSDL file. This is especially so in a code-first development environment where the WSDL is automatically generated.

For those who cannot afford time to read the specifications, I’ve tried to summarise the salient concepts for both WSDL 1.1 and WSDL 2.0 in the following UML Class Diagrams.

In the following diagrams, the colour annotations follows:

  • Blue denotes type/ schema definitions
  • Orange denotes abstract interface definitions
  • Yellow denotes concrete definitions
  • Green denotes message definitions

WSDL 2.0 Conceptual Model

You should note that the main differences between 1.1 and 2.0 are:

  1. Definition is now Description
  2. PortType is now Interface
  3. Message definitions have been deprecated and so have the message bindings
  4. Port is now EndPoint
  5. Address, formerly a standalone element, is now an attribute of EndPoint
  6. Fault is now at the Interface level (instead of Operation) and is reusable

Understanding ITIL Service Management the UML way…

I originally had a great deal of difficult reconciling the differences amongst ITIL Change Management, Incident Management, and Problem Management. Having researched on the subjects and understanding them better now, I’ve tried to put the concepts together using a UML class diagram to capture my understanding and to keep it imprinted. Similarly, I wanted to differentiate the various categories of changes (Standard, Emergency, Normal) using an easy to understand & self-explanatory manner – a UML Activity Diagram!

How to depict (Professional-Looking) Logical Network Diagrams in Astah

I have always had to create (professional-looking) UML diagrams using Visio-like icons. You’ve got to admit that showing a bunch of boring UML boxes hardly interests anyone less technical (like anyone whose designation has the words “manager” or “director”). This is actually possible in Astah! I’ve created a template for future projects that allows me to produce logical network diagrams that look like the following: To create this diagram, you need to do the following: Assign various icons to stereotypes. I created the following for my use: Create a new UML Deployment Diagram Every element in the diagram is created as a Node The nodes are subsequently assigned the appropriate <<stereotype>>. E.g. Internet is <<internet>>, WebZone FW is <<firewall>>, Web LB is <<loadBalancer>> Ensure the “Icon Notation” is set to “Customized Icon” for each node Instead of the boring boxes, the corresponding icons automatically gets displayed!
