Dp-3015: Getting Started With Cosmos DB Nosql Development

The DP-3015: Getting Started with Cosmos DB NoSQL Development course teaches developers how to build applications using Azure Cosmos DB for NoSQL. This 8-hour hands-on course covers Cosmos DB resource configuration, NoSQL data modeling, SDK operations, point queries, data partitioning strategies, and building scalable cloud-native applications with globally distributed data. Esamatic srl, a Microsoft Learning Partner in Milan, delivers this course with Microsoft Certified Trainers.

• Applied Skills Credential: validates competency in Cosmos DB NoSQL development
• Cosmos DB Configuration: account setup, database and container provisioning, throughput management
• NoSQL Data Modeling: document design, embedding vs referencing, and denormalization patterns
• SDK Operations: CRUD operations, point reads, and cross-partition queries using the .NET or Python SDK
• Partitioning Strategy: partition key selection, logical and physical partitions, and hot partition avoidance

Course Overview: DP-3015 Cosmos DB NoSQL Development

Azure Cosmos DB is Microsoft’s globally distributed, multi-model database service designed for low-latency, high-throughput applications. The DP-3015 course focuses on the NoSQL API, providing practical experience with resource management, data modeling for NoSQL workloads, SDK-based data operations, query optimization, and partitioning strategies for building performant, scalable applications.

Learning Objectives

1. Configure Cosmos DB resources — create accounts, databases, and containers with appropriate throughput and consistency settings
2. Design NoSQL data models — model documents for efficient reads, select embedding vs referencing strategies, and implement denormalization
3. Perform SDK operations — execute CRUD operations, point reads, and queries using the Cosmos DB SDK
4. Implement partitioning strategies — select effective partition keys, understand partition distribution, and optimize for cross-partition queries

Who Should Attend

This course is ideal for developers and software engineers seeking to build cloud-native applications with Azure Cosmos DB NoSQL, particularly those designing applications requiring global distribution and low-latency data access.
