What type of database is Amazon DynamoDB?

1. Relational Database

2. NoSQL Database

3. Graph Database

4. Time Series Database

The correct answer is: NoSQL Database

Amazon DynamoDB is classified as a NoSQL database, making it well-suited for applications requiring high performance, scalability, and flexibility in data models. NoSQL databases are designed to handle large volumes of unstructured and semi-structured data, which can be distributed across many servers. This architecture allows DynamoDB to provide low-latency access to data at any scale. DynamoDB employs a key-value store design, allowing developers to create tables with items that can have varying attributes. This flexibility contrasts with traditional relational databases, which require a predefined schema and are structured in tables with fixed rows and columns. As a NoSQL database, DynamoDB supports various data types and structures like documents and key-value pairs, making it a versatile option for modern applications that may require rapid scaling and agile development practices. By using DynamoDB, organizations can benefit from features such as automatic sharding, built-in security, and backup capabilities, which enhance productivity and facilitate the development of robust applications that need to grow quickly without extensive database management.
