Study Notes
AISPrE 2: REVIEWER - MODULE 1
- System Development is a systematic process encompassing phases like planning, analysis, design, deployment, and maintenance.
- System Analysis involves fact-gathering, problem identification, and breaking down systems into their components.
- System Design plans new systems or replaces existing ones, defining components for specific requirements.
What is a System?
- System is derived from Greek word Systema meaning an organized relationship between components achieving a shared purpose.
- A system is an orderly grouping of interconnected components that work collectively according to a plan to accomplish a particular goal.
Properties of a System
- Organization: Structured and ordered arrangement of components to achieve objectives.
- Interaction: How components operate with each other.
- Interdependence: Components relying on each other for functionality.
- Integration: Components’ connection within the system.
- Central Objective: A system's primary (stated or real) goal.
Elements of a System
- Inputs: Information entering the system for processing.
- Outputs: Results of the processing.
- Processor: Part transforming input into output.
- Control: Decision-making subsystem governing activities for processing input and producing output.
AISPrE 2: REVIEWER - MODULE 1
- Feedback: Provides control in dynamic systems; positive encourages performance, negative informs for action.
- Environment: The broader system influencing an organization; external elements influencing it.
Types of Systems
- Physical Systems: Tangible, touchable entities (desks, chairs).
- Abstract Systems: Conceptual or non-physical entities (formulas, models).
- Open Systems: Interact with their surroundings exchanging inputs and outputs.
- Closed Systems: Isolated from environment.
Adaptive and Non-Adaptive Systems
- Adaptive: Adjusts in response to environment, examples are human beings and animals.
- Non-adaptive: Doesn't change based on surroundings, examples are machines.
Permanent vs Temporary Systems
- Permanent: Enduring systems; examples are business policies.
- Temporary: Systems with a defined lifespan; examples are setups for programs like DJs.
Natural and Manufactured Systems
- Natural Systems: Systems created by nature; examples are solar systems.
- Manufactured Systems: Systems created by humans; examples are spaceships, dams, and machinery.
Deterministic vs Probabilistic Systems
- Deterministic Systems: Predictable behavior; outputs determined by inputs.
- Probabilistic: Uncertain behavior; outputs not entirely determined by inputs.
AISPrE 2: REVIEWER - MODULE 2
- System Development Life Cycle (SDLC): A structured approach to developing/modifying systems.
System Analysis
- System Planning: Defining goals and tasks for new system initiatives.
- Analysis: Understanding existing business needs before system development.
- Requirements Anticipation: Predictions about system characteristics based on previous experiences.
- Requirements Investigation: Assessing current system features and documenting.
- Requirements Specifications: Determining required features and capabilities describing new systems specifications and details.
- Information Gathering Techniques: Methods like interviews, questionnaires and observations used for gathering data.
AISPrE 2: REVIEWER - MODULE 3
- Software Development Methodology: A framework guiding system development processes.
Types of Methodologies
- Agile Software Development: Flexible method that allows changes.
- DevOps Methodology: Integration of development and IT operations.
- Waterfall Methodology: A linear, sequential, traditional approach.
- Prototype Methodology: Developing a prototype to demonstrate functionality to clients.
- Feature Driven Development (FDD): An iterative model good for transitioning from phase-based to iterative approach.
Rapid Application Development (RAD):
- An effective methodology focused on faster development and better quality outcomes.
Spiral Model:
- A model emphasizing early risk identification and mitigation.
AISPrE 2: REVIEWER - MODULE 4
- System Planning: Establishing the initial needs for a system before development.
- Requirements: The necessary specifications or components for a system that include the processes, data capture, data output, and overall data management system.
- Requirements Determination: Evaluating and collecting details about the existing system to identify what is required for a new or enhanced one.
AISPrE 2 :REVIEWER - MODULE 5
- Structured Analysis: A method for logically grasping systems and their operations.
- Decision Trees: Diagrams illustrating decision-making paths based on different conditions.
- Decision Tables: Matrixes delineating conditions and resulting actions.
- Structured English: A method for precise, procedural descriptions.
- Pseudocode: Using plain English to express system logic.
AISPrE 2: REVIEWER - MODULE 6
- Feasibility Study: Preliminary investigation into the viability and practicality of a new system.
- Types of Feasibilities: Economic, operational, behavioral and schedule.
- Data Flow Diagrams (DFD): Visual representations of data and their movement.
- Entity-Relationship Model (E-R Model): Technique used in database design for relating various entities of an organization.
AISPrE 2: REVIEWER - MODULE 7
- System Design: A critical phase bridging the problem domain and the functional system for managing expectations.
- Types of System Design: Logical design (data flow diagram) and physical design (actual processes, inputs and outputs detailed).
File Organization
- Serial: Stored sequentially by order.
- Sequential: Ordered by a unique identifier.
- Direct/Relative: Stored through a calculated address.
- Indexed: Sequential and random accessing of records.
File Access Methods
(e.g. Sequential, Random).
Modules Design Strategies
- Top-down strategy: Breaking down a system into modules from top to bottom.
- Bottom-Up Strategy: Developing the system from the basic functional components, upwards to the higher level modules.
- Transform-Centered: Transactions all follow the same path.
- Transaction-Centered: Transactions do not all follow the same path.
System Documentation
- Program Documentation: Details about inputs, outputs and processes.
- System Documentation: Technical details, requirements and specifications.
- Operations Documentation: Operations and distributed outputs.
