Which of the following is a characteristic of Azure Cosmos DB?

Azure Cosmos DB is a fully managed, globally distributed database service that supports multiple data models, including document, graph, and key-value. One of its significant strengths is its support for SQL queries and the ability to handle document data modeling. This flexibility allows developers to use their preferred query language and data structure when developing applications, making it easier to integrate with various existing solutions and data formats.

Moreover, Azure Cosmos DB automatically manages indexing for the data, which enhances performance and reduces the complexity of managing databases compared to traditional RDBMS systems where manual index management is often necessary. It’s designed to handle multiple types of data structures, which provides a versatile environment for applications. Its architecture is optimized for high availability and fast response times, often outperforming traditional databases, especially in scenarios requiring global distribution and scalability.

The ability to support SQL for querying adds another layer of accessibility, allowing developers who are familiar with relational database concepts to leverage their skills when working with non-relational data structures, which broadens its usability across different application domains.
