Chapter 1 - Introduction to System Analysis and Design

4. The physical layer of an information system, which includes servers, workstations, and networks.
5. A system development method that is a traditional technique focusing on processes and data flow.
6. A system development method that views the system in terms of objects that combine data and processes.
12. This type of system helps solve problems and make decisions by analyzing data and showing "what-if" scenarios.
16. The raw material that an information system transforms into useful information.
17. The final stage of the SDLC, where bugs are fixed, and the system is updated as needed.
18. The phase of the SDLC where code is written and system parts are connected.
19. An information system has five key components: hardware, software, data, people, and processes.
20. A system development method that is very flexible and efficient in dealing with change, stressing team interaction.

1. A system that records daily business activities, like sales and payments.
2. The creation of a specific timetable is part of the scheduling phase of project management.
3. This involves breaking a project down into a series of smaller tasks.
7. A development method that attempts to develop a system incrementally by building a series of prototypes and constantly adjusting them to user requirements.
8. A horizontal bar chart that represents a set of tasks and is used for project scheduling.
9. The phase where you plan how the system will work, including its layout and database.
10. This refers to the programs that control the hardware and produce the desired information or results.
11. The phase where the system is launched to real users.
13. An iterative development model that combines elements of both waterfall and prototyping methodologies.
14. Data that has been transformed into output that is valuable to users.
15. A linear sequential approach where phases are processed and completed one at a time and do not overlap.
