Programming Azure Cosmos DB: Transactions, Triggers, and Custom Queries

Modern cloud applications demand highly performant and consistent data operations. When standard SQL queries are not enough, extending your database logic directly on the server is the key to unlocking maximum efficiency. This course teaches you how to write, deploy, and manage server-side programming constructs in Azure Cosmos DB for NoSQL. You will transition from executing basic queries to implementing complex transactional workflows and custom business logic directly within your database container. What you'll learn: - Understand the core architecture of server-side programming in Azure Cosmos DB - Write and execute user-defined functions (UDFs) in JavaScript to customize query results - Implement pre-triggers and post-triggers to validate and modify documents during write operations - Author stored procedures to perform multi-document transactional operations safely - Apply transactional batching techniques to group multiple operations together efficiently - Manage Request Units (RUs) and optimize server-side execution performance You will start by exploring the foundational concepts of server-side execution and transaction boundaries in NoSQL databases. Then, you will progress through structured text-based lessons with practical code snippets that demonstrate how to write, register, and execute JavaScript logic safely and efficiently. This course is designed for database developers, cloud engineers, and backend programmers who are new to server-side development in Azure Cosmos DB. Basic familiarity with SQL and JavaScript is helpful, but no prior database programming experience is required. Start reading today to elevate your database operations with server-side programming.
