A startup requires a NoSQL database with minimal maintenance. Which database is the best option?

• A. Amazon DynamoDB
• B. PostgreSQL
• C. SQLite
• D. MariaDB

Answer: (A)

Amazon DynamoDB is the most suitable choice for a startup looking for a NoSQL database with minimal maintenance. DynamoDB is a fully managed, serverless database service that automatically handles scalability, replication, and backups without requiring direct intervention from users. This allows startups to focus more on developing their applications rather than managing database infrastructure.

DynamoDB's design is optimized for performance and scalability, enabling it to handle large volumes of traffic and data seamlessly. Its serverless model means that the startup does not have to provision or manage servers, and it automatically scales up or down based on the demand for its services. This feature greatly reduces the operational burden, making it an ideal solution for teams that may not have extensive database management experience or resources.

In contrast, PostgreSQL, SQLite, and MariaDB are relational database management systems that typically require more maintenance in terms of schema management, querying performance tuning, and manual scaling. They also involve more complex setup and configuration, which may not be ideal for a startup aiming for rapid development and deployment.
