Study Notes
Waterfall Methodology
- Waterfall Methodology is made up of 7 phases: Requirements, Design, Implementation, Integration and Testing, Deployment and Maintenance.
- The Requirements phase involves capturing all system requirements and documenting them into a System Requirement Specification (SRS) Document.
- The Design phase studies the SRS and defines the overall system's architecture.
- The Implementation phase develops the system in small programs called units, which are integrated in the next phase, with each unit tested for functionality.
- The Integration & Testing phase involves integrating all units into a system, testing each unit, and then testing the whole system for any errors or failures.
- The Deployment phase deploys the system into the customer environment or releases it to the market. This happens after testing.
- The Maintenance phase focuses on fixing any issues that arise in the customer environment.
- It also aims to enhance the product and release better versions.
Structured Systems Analysis and Design Methodology (SSADM)
- SSADM was a popular methodology used in the late 80s and is a rigid and document-led approach to system design.
- SSADM is known for its strong approach to complex database designs and has strategies to align business needs with system development
- SSADM can be broken down into 5 phases: Project Definition, Feasibility Study, Requirements Analysis, Logical Design, and Physical Design
SSADM Phases
- The Project Definition phase establishes project objectives and involves the areas of the business within the project.
- It involves creating a Project Initiation Document, outlining the terms of reference.
- The terms of reference defines the objectives and scope of the investigation, the available resources and timescales, and any limitations and constraints.
- The Feasibility Study decides if the project is viable before too many resources are committed.
- The Feasibility Study aims to understand the present system and its problems, identify new system requirements, identify a range of potential solutions, and assess cost/benefit implications.
- The Requirements Analysis phase refines the requirements based on the chosen business system option.
- The Logical Design phase specifies the physical data, processes, inputs, and outputs.
- The Logical Design is broken down into Dialogue Design, Define Update Processing, and Define Enquiry Process.
- The Physical design includes tasks like: Create Physical Design Strategy, Overview of Physical Data and Process Design, Space and Performance, and Physical Process Specification.
V-Model
- The V-Model is based on the Waterfall model but has been modified and derived from it.
- The V-Model has bent phases upwards, forming a 'V', to show the testing phases associated with each phase.
- The horizontal dimension represents the project completeness, and the vertical dimension represents the system's multiple levels, with the topmost level being the system's context and the bottommost level being the parts that are defined as a black-box view.
