Structured Systems Analysis and Design Method
Introduction
SSADM is a methodology for analysis and design of information systems.
SSADM techniques
- Logical Data Modeling: This is the process of identifying, modeling and documenting the data requirements of the system being designed. The data are separated into entities and relationships.
- Data Flow Modeling: This is the process of identifying, modeling and documenting how data moves around an information system. Data Flow Modeling examines processes, data stores, external entities and data flows.
- Entity Behavior Modeling: This is the process of identifying, modeling and documenting the events that affect each entity and the sequence in which these events occur.
Stages
- Stage 0 - Feasibility study
- Stage 1 - Investigation of the current environment
- Stage 2 - Business system options
- Stage 3 - Requirements specification
- Stage 4 - Technical system options
- Stage 5 - Logical design
- Stage 6 - Physical design
