System Development Life Cycle
Candidates should understand the main components of the SDLC and how they may be applied to the development of a computerised solution as listed below.
System Investigation - Analysis of existing system and feasibility report
(a) Existing Hardware and Software
(b) Definition of the scope of the present system
(c) Major data processing functions and processes
(d) Identification of problems with the present system
(e) Identify user requirements for the new system
(f) Analysis of costs and benefits of the new system
System Analysis - Identify and understand tools and techniques used to analyse a system.
Identify external and internal components to a system and the flow of data between them including Data Flow Diagrams (DFDs), including High level (contextual view) DFDs and low level (detailed view) DFDs, decision tables and systems diagrams.
Candidates must be able to use all of the elements of a Data flow diagram correctly including:
Data dictionaries.
Entity Relationship diagrams.
Candidates should understand that a ‘Data Model’ includes an:
Entity relationship modelling - candidates should be able to draw and interpret ERM diagrams: one to one, one to many, many to many.
System Design
Design of hardware, software, data and file structures, information systems, network and data transmission issues, personnel issues and security processes and procedures.
System Investigation - Analysis of existing system and feasibility report
(a) Existing Hardware and Software
(b) Definition of the scope of the present system
- Organisational chart
- Define sources of data
- Methods of data capture
(c) Major data processing functions and processes
- High level (contextual view) data flow
(d) Identification of problems with the present system
(e) Identify user requirements for the new system
(f) Analysis of costs and benefits of the new system

Candidates must be able to use all of the elements of a Data flow diagram correctly including:
- flow direction line
- process
- entity
- data store
Data dictionaries.
Entity Relationship diagrams.
Candidates should understand that a ‘Data Model’ includes an:
- Entity - Places, object or people represented by data in a spreadsheet or database
- Attribute - Information of facts about an entity
Entity relationship modelling - candidates should be able to draw and interpret ERM diagrams: one to one, one to many, many to many.
