What role does indexing play in query optimization?
- Adds redundancy to the database
- Improves search performance by providing faster access to data
- Reduces data integrity
- Slows down query execution
Indexing plays a crucial role in query optimization by improving search performance. Indexes provide faster access to specific rows in a table, reducing the time it takes to retrieve data and optimizing query execution.
What is one potential risk associated with live data migration?
- Data Consistency Issues
- Data Corruption
- Data Duplication
- Downtime
One potential risk associated with live data migration is the possibility of data corruption. During the migration process, there is a chance that data may become corrupt or incomplete, leading to inconsistencies and potential issues in the new system. This risk underscores the importance of thorough planning and testing to minimize such occurrences.
A client wants their website to be accessible on all devices without compromising user experience. How would you approach this requirement in your responsive design?
- Conduct thorough testing on various devices
- Employ fluid grid layouts
- Implement responsive breakpoints
- Use a mobile-first approach
A mobile-first approach ensures that the design starts with the smallest screens, providing a solid foundation for responsiveness across all devices.
You're working on an application that requires efficient handling of real-time data streams. Which data structure and algorithmic approach would you employ?
- Circular Buffer with Sliding Window
- Linked List
- Recursive Descent Parsing
- Stack Data Structure
A Circular Buffer with a Sliding Window is effective for handling real-time data streams. It allows continuous data processing with constant time complexity, making it suitable for scenarios where data arrives in a continuous stream.
What is the purpose of a pull request in version control systems like Git?
- Checking out code
- Committing code directly
