Q2. i. Describe the key guidelines for data design

1. Explain the different functions of architectural design. 5+5

Ans 2.

(i) Key Guidelines for Data Design

Data design defines how information is structured, stored, and accessed throughout the software system. Effective data design ensures consistency, accuracy, reliability, and efficient handling of input and output operations. One essential guideline is understanding the data requirements clearly before creating models. Designers must analyze what data needs to be captured, how it flows, and how it will be used across modules. Normalization rules help eliminate redundancy and ensure data

 

Q3. Briefly describe the various approaches to software process assessment and improvement. 10   

Ans 3.

Approaches to Software Process Assessment and Improvement

Software process assessment and improvement aim to evaluate existing development practices, identify weaknesses, and enhance the overall efficiency, quality, and predictability of software projects. Organizations adopt structured frameworks to measure process maturity and implement improvements systematically.

2. White Box Testing
3. Regressing Testing 5 + (2.5+2.5)

Ans 4.

Characteristics of Software Testing

Software testing is an essential activity in the software development life cycle because it ensures that the final product is reliable, accurate, and aligned with user requirements. One important characteristic of software testing is that it aims to detect defects rather than to prove that software is error-free. Testing works on the principle that the presence of defects can be revealed through systematic evaluation,

 

 

Q5. Define Software maintenance and explicate its various tasks. 2 + 8 

Ans 5.

Software Maintenance and Its Various Tasks

Software Maintenance

Software maintenance refers to the continuous process of modifying, enhancing, correcting, and updating software after it has been delivered to the user. It ensures that the software remains functional, secure, efficient, and adaptable to new business needs, technological advancements, and user expectations. Maintenance is an essential part of the software life cycle because software often operates for many

 

Q6. i. Briefly describe the Process of Agile Software Development.

1. Distinguish between traditional software engineering and modern software engineering. 5 +5

Ans 6.

Agile Software Development Process & Traditional vs Modern Software Engineering

Process of Agile Software Development

Agile software development is an iterative, flexible, and customer-centric approach that focuses on delivering small, workable parts of software at frequent intervals. The process begins with gathering high-level requirements in the form of user stories that express what users expect from the system. These stories are prioritized based on business value, and the project is divided into short, time-boxed cycles
