Decision tree modeling
How do you model logic using decision tree? Explain with an example. [5]
A decision tree is a tree-structured model used to represent decisions and their possible consequences. It models logical conditions (if-then-else logic) in a hierarchical, visual form that is easy to understand and implement. --- Component Description ----...
Full solved answer →Decision table with examples
Explain decision table with example. [5]
A decision table is a structured tabular representation used in software testing and requirements analysis to model complex business logic involving multiple conditions and their corresponding actions. It systematically lists all possible combinations of co...
Full solved answer →Documentation importance
Why documentation and training are important? [5]
--- Documentation refers to the written records that describe a system, its components, how it works, and how it should be used. It is important for the following reasons: - Documentation serves as a permanent reference for developers, users, and administra...
Full solved answer →Pseudocode definition and examples
Explain pseudocode with example. [5]
Pseudocode is an informal, high-level description of an algorithm that uses a mixture of natural language and programming-like constructs to describe the steps of a solution. It is not written in any specific programming language syntax, so it cannot be dir...
Full solved answer →System maintenance factors and maintainability
Explain different factors that influence maintainability of the information system. [5]
Note: The reference notes did not contain specific content on this topic. The following answer is based on standard Software Engineering and Information Systems curriculum as taught in BSc CSIT programs. --- Maintainability refers to the ease with which an ...
Full solved answer →Software testing importance
Why software testing in important? Explain any three software testing techniques. [5]
Software testing is a critical phase in the software development life cycle (SDLC). It is important for the following reasons: - Defect Detection: Testing identifies bugs and errors in the software before it is delivered to the end user, reducing the cost o...
