Explain the concept of normalization in database management.

• Normalization is only applicable to non-relational databases.

• Normalization in database management is the process of organizing data in a database efficiently by breaking down a database into smaller, related tables to minimize redundancy and dependency.

• Normalization involves combining all data into a single table for simplicity.

• Normalization is the process of adding redundancy to a database to improve performance.

What is the purpose of a test plan in software testing?

• To waste time and resources

• To provide entertainment during testing

• To confuse the testing team

• The purpose of a test plan in software testing is to outline the scope, approach, resources, and schedule for testing activities.

How do you ensure quality assurance in software development?

• By ignoring coding standards

• By never testing the software

• By not monitoring the development process

• By following a structured testing process, conducting code reviews, implementing automated testing, using version control systems, adhering to coding standards, and continuously monitoring and improving the development process.
