Store and Analyze JSON Data Using the Oracle API for MongoDB and SQL/JSON

Many developers like the MongoDB API for building applications. You can now use that same easy-to-use API against Oracle Autonomous Database. Simply bring your MongoDB application to Autonomous Database and inherit the security, availability, and manageability of the service. Plus, you can use Oracle SQL to analyze both your JSON collections and your relational data from your favorite SQL tools and applications. During this session, we will build a low-latency microservice using the Oracle API for MongoDB and then show how the backing collections can be queried directly using SQL.
