Learning Outcome 2

Learners will be able to:

appreciate the architecture of Web-based systems
model Web-based systems
use a generalised notation to present their models (UML)
appreciate issues surrounding the implementation of Web-based systems
prototype Web-based systems using appropriate technologies

What event will trigger the application of the learning?	What degree of success will learner accomplish?
When the learner needs to gather user requirements, to produce software specification for Web-based e-Business applications, and to to demonstrate functionality of these applications through prototyping.	Learner will be able to explain the characteristics of client server architectures, to use UML diligently to model Web-based systems, and to programme software components in Java and Net framework.

Learning Objectives in the 'Mandatory Objectives' column refer to the bare minimum you need to learn to pass. It is essential that this learning is undertaken.

Successful completion of the 'Honours' column, together with the 'Mandatory Objectives' column, will prepare you more thoroughly.

If you complete all of the learning in each column, then you will be in the best position to obtain a high mark during the assessments.

For each category, click on individual Learning Objectives to access the relevant learning material.
