Your company plans to develop an application that will use a NoSQL database. The database will be used to store transactions and customer information by using
JSON documents.
Which two Azure Cosmos DB APIs can developers use for the application? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

A. Gremlin (graph)

B. MongoDB

C. Cassandra

D. Core (SQL)

E. Azure Table






 

Suggested Answer: AD

D: The SQL API supports cross-document transactions expressed as JavaScript-stored procedures and triggers. Transactions are scoped to a single partition within each container and executed with ACID semantics as "all or nothing," isolated from other concurrently executing code and user requests. If exceptions are thrown through the server-side execution of JavaScript application code, the entire transaction is rolled back.
A: Azure Cosmos DB is Microsoft's globally distributed, multi-model database service. Where multi-model means Azure Cosmos DB supports multiple APIs and multiple data models, different APIs use different data formats for storage and wire protocol. For example, SQL uses JSON, MongoDB uses BSON, Table uses
EDM, Cassandra uses CQL, Gremlin uses JSON format. As a result, we recommend using the same API for all access to the data in a given account.
Each API operates independently, except the Gremlin and SQL API, which are interoperable.
