Common Questions about DP 420 (FAQ) 

What is the difference between Azure DB and Cosmos DB?  

Azure DB is a broad term encompassing various Azure database services, while Cosmos DB is a specialized, globally distributed, multi-model database service on Azure. Cosmos DB supports multiple data models, including document, key-value, graph, and column-family, providing unparalleled flexibility for diverse application requirements. Its global distribution ensures low-latency access to data worldwide, setting it apart from traditional Azure database offerings. 

Is Azure Cosmos DB SQL or NoSQL?  

Azure Cosmos DB is a versatile multi-model database service that accommodates both SQL and NoSQL data models. This adaptability allows developers to choose the most suitable data model for their application, whether it follows a structured SQL approach or embraces the flexibility of NoSQL for unstructured or semi-structured data. This unique capability positions Azure Cosmos DB as a comprehensive solution catering to a wide range of application scenarios. 

Which is the native API for Cosmos DB?  

Azure Cosmos DB provides multiple APIs, each tailored to support specific data models. However, the SQL API, formerly known as DocumentDB, is considered the native API for Cosmos DB. This API is designed to seamlessly integrate with JSON data structures and offers a familiar SQL-like language for querying and manipulating data. Choosing the SQL API ensures optimal compatibility and performance within the Cosmos DB environment. 

What type of cloud service is Azure Cosmos DB?  

Azure Cosmos DB is a fully managed, globally distributed, and multi-model database service that operates within the Platform as a Service (PaaS) model in cloud computing. As a PaaS offering, Cosmos DB abstracts the complexities of database management, allowing developers to focus on building applications without the burden of infrastructure management. Its global distribution, automatic scalability, and comprehensive support for various data models make it a robust and versatile solution for modern cloud-based applications.
