Part 3  Implementation

Summary

1 

Analysis of business and user requirements for digital business systems is impor-

tant in delivering usable and relevant systems.

2 

Process modelling is used to assess existing business processes and suggest 

revised processes. Techniques such as task analysis and flow process charts from 

workflow design are useful in understanding tasks that must be supported by the 

system and weaknesses in the current process.

3 

Data modelling for digital business systems mainly involves traditional entity rela-

tionship approaches.

4 

Architectural designs involve assessing appropriate integration between legacy 

systems and new e-commerce systems. Such designs are based on the  client– 

 server  approach.

5 

User interface design can be improved through using structured approaches such 

as  use-  case and following evolving standards for site structure, page structure and 

content.

6 

Security design is important to maintain trust amongst the customer base. Security 

solutions target protecting servers from attack and prevent interception of mes-

sages when they are in transit.
