1.2. Spiral model
1.3. Iterative and incremental development
1.4. Agile model
1.5. Prototyping model
1.6. Rapid Application Development (RAD)
1.7. Joint Application Development (JAD)
2. Project management activities
2.1. Initiation: Define the project, set objectives, and identify stakeholders.
2.2. Planning: Develop detailed plans, including scope, schedule, budget, and resources.
2.3. Execution: Implement the plan, manage teams, and complete project tasks.
2.4. Monitoring and Controlling: Track progress, manage changes, and ensure quality.
2.5. Closure: Finalize and deliver the project, obtain approvals, and document lessons learned.
3. Define the meaning of information and information system?
3.1. Information is processed data that is meaningful and useful for decision-making and problem-solving.
3.2. An Information System is a coordinated system consisting of hardware, software, data, procedures, and people that collects, processes, stores, and disseminates information to support decision-making and organizational processes.
4. Describe the information system components?
4.1. Hardware: The physical devices and equipment used in the system, such as computers, servers, and networking devices.
4.2. Software: The programs and applications that process data and manage system resources.
4.3. Data: The raw facts and figures that are processed to produce meaningful information.
4.4. Procedures: The policies, methods, and rules governing the operation and use of the information system.
4.5. People: The users and IT professionals who interact with and manage the system, including administrators, analysts, and end-users.
5. Identify the various types of information system?
5.1. Transaction Processing Systems (TPS): Systems that manage and record daily routine transactions, such as sales order entry and payroll.
5.2. Management Information Systems (MIS): Systems that provide summarized and structured information to managers to support decision-making and organizational control.
5.3. Decision Support Systems (DSS): Systems that assist in making non-routine decisions by analyzing large volumes of data and presenting potential solutions.
5.4. Executive Information Systems (EIS): Systems designed to provide top executives with easy access to internal and external information relevant to strategic decision-making.
6. system development method
6.1. Structured Analysis
6.1.1. Uses a top-down approach to break down a system into parts, with a focus on detailed documentation and diagrams to represent processes and data flows.
6.2. Object-Oriented Analysis
6.2.1. Models systems as interacting objects, emphasizing encapsulation, inheritance, and polymorphism to enhance modularity and reusability.
6.3. Agile/Adaptive Method
6.3.1. An iterative and incremental approach prioritizing flexibility, customer collaboration, and rapid delivery, allowing for continuous feedback and adaptation to changing requirements.
7. System Development Life Cycle (SDLC)
7.1. Planning :
7.1.1. Identify the need for a new system, define project scope, and conduct feasibility studies.
7.2. Analysis :
7.2.1. Gather and analyze system requirements from stakeholders to understand what the new system should achieve.
7.3. Design :
7.3.1. Develop the system's architecture, including user interfaces and data models, based on gathered requirements.
7.4. Implementation :
7.4.1. Convert design specifications into a working system through coding and integration of system components.
7.5. Testing :
7.5.1. Check the system for defects and verify that it meets the required specifications.
7.6. Deployment :
7.6.1. Install and configure the system in the production environment and train users.
7.7. Maintenance :
7.7.1. Continuously monitor, update, and enhance the system to ensure it remains effective and relevant.
