18 Questions
What does the state of a system represent?
Conditions about the system
What is the purpose of using state in the partitioning process?
To create detailed analysis for each state
In what type of software is the state approach commonly used?
Real-time software or process-control software
What characterizes the informal approach to analysis?
Strict adherence to defined methodology
How is information obtained in the informal approach to analysis?
Through interaction with clients and end users
What does the analyst do in the early meetings with clients and end-users in the informal approach to analysis?
Act as a listener and absorb information provided
What is the main reason for the usefulness of informal approaches to analysis?
They are not very risky in introducing errors.
Which technique is often referred to as the structured analysis technique?
Data Flow Modeling
What does a Data Flow Diagram (DFD) primarily aim to capture?
The flow of data through a system
In Data Flow Modeling, what is a 'process' or a 'bubble'?
A data transformation agent
What term is used to describe the repository of various data flows defined in a Data Flow Diagram?
Data Dictionary
Which approach is a top-down refinement technique used in structured analysis for producing specifications?
Structured analysis and specification
What is the main aim of problem analysis in software design?
To understand the needs of the clients and users
How is the complexity managed during software design?
Through decomposition and building structures as abstractions
What is the role of abstract requirements in software design?
To help in competitive bidding and feasibility analysis
What approach is commonly used to start problem analysis in software design?
Divide and conquer by partitioning the problem into sub problems
Why do clients and users often not fully understand all their needs for a new system?
Because the potential of the new system is often not fully appreciated
How does problem analysis help in understanding the total problem in software design?
By understanding each sub problem and its relationship to other sub problems
Test your knowledge on conceptual modeling-based approaches and informal analysis in system analysis and design. Explore the differences between the two methods and understand when an informal approach may be more practical. Identify the strengths and weaknesses of data flow modeling in the context of system analysis.
