Information system is a combination of…
Software, Hardware, Telecommunication networks
What does SDLC stand for?
System Development Life Cycle
Give a short defenition of planning stage
The planning stage (also called the feasibility stage) is exactly what it sounds like: the phase in which developers will plan for the upcoming project.
Give a short defenition of analysis stage
Is the second phase of the SDLC, where the objective is to gather and analyze the requirements of the software system to be developed.
Give a short defenition of design stage
In this phase, the requirement gathered in the SRS document is used as an input and software architecture that is used for implementing system development is derived.
How many basic types of information system?
5
What Are the 7 Phases of SDLC?
The new seven phases of SDLC include planning, analysis, design, development, testing, implementation, and maintenance.
What are the main activities of the planning phase?
During this phase, all the relevant information is collected from the customer to develop a product as per their expectation.
What tools can you use during analysis phase?
Word
Excel
PowerPoint
Apps for analysis
What are the main activities of the design phase?
Designing the system architecture
Creating data models and diagrams
Developing algorithms and
code structures
Designing the user interface
Identifying hardware and software
requirements
Creating test cases and planning for testing
What tools are an examples of information system?
Tools such as laptops, databases, networks, and smartphones are examples of information systems.
What Does SDLC Develop?
SDLC can be used to develop or engineer software, systems, and even information systems. It can also be used to develop hardware or a combination of both software and hardware at the same time.
What are the goals of the planning phase?
The purpose of the Planning Phase is to plan all project processes and activities required to ensure project success and to create a comprehensive set of plans, known as the PMP, to manage the project from this phase until project termination.
What are the main activities of the analysis phase? (at least 2 )
Requirements gathering
Requirements analysis
Feasibility study
Functional specification
Technical specification
What are the goals of the design phase?
Six Major Types of Information Systems ( at least 3 )
Transaction Processing System (TPS)
Office Automation System (OAS)
Knowledge Work System (KWS)
Management Information System (MIS)
Decision Support System (DSS)
Executive Support System (ESS)
Basic SDLC Methodologies ( at least 2 )
Waterfall Model
Iterative Model
Spiral Model
V-Model
Big Bang Model
Agile Model
What tools can you use during planning phase?
RealtimeBoard
Search engines
Different documents
Notes
What are the goals of the analysis phase?
The goal of the SDLC is to produce superior software that meets and exceeds all customer expectations and demands. The SDLC defines and outlines a detailed plan with stages, or phases, that each encompasses its process and deliverables
hardware alternatives
Hardware alternatives refer to the physical components that make up the system such as servers, desktops, laptops, mobile devices, and other computing equipment
Some broad categories that highlight types of information system applications ( at least 2 )
Communication. Information system applications allow rapid data sharing on a global scale.
Education. Information systems help make remote learning easier (particularly useful during pandemics) and make people more comfortable with tech advancements such as smartphones, tablets, and other network devices.
Employment. The advent of information systems has directly resulted in creating new positions such as data analyzers and cyber-security experts.
Finance. Information systems make the transfer of funds more manageable and more secure.
Healthcare. Thanks to information systems, healthcare providers can access vital medical records faster.
Security. Information systems make it easier to employ data safeguards to reduce the likelihood of a data breach or malware.
Benefits of SDLC ( at least 4 )
Clear Goal Descriptions
Proper Testing Before Installation
Clear Stage Progression
Member Flexibility
Perfection Is Achievable
No One Member Makes or Breaks the Project
What are the critical questions during this stage?
What is the goal of the new project?
What is the business hoping to get from the product?
Is the team going to write code from scratch, or are we upgrading an existing system?
Do we have any hard deadlines?
Do we have the necessary knowledge in-house, or will we have to outsource some part(s) of the project?
What is Technical specification?
This is a document that describes the technical requirements of the software system, such as hardware and software platforms, programming languages, and tools.
Software alternatives
Software alternatives refer to the programs and applications that run on the hardware such as operating systems, programming languages, databases, and other software tools
