Who Should Take This Course

• Database Administrators (DBAs) who are currently specializing in relational systems like SQL Server, Oracle, or PostgreSQL and need to transition into the non-relational ecosystem.
• System and Solution Architects responsible for designing scalable, high-performance distributed systems that can handle massive volumes of unstructured data.
• Data Scientists and Analysts who require more efficient ways to query and manipulate semi-structured data for big data analytics and machine learning.
• Backend Developers working with microservices who want to move beyond simple CRUD operations and master professional data modeling in NoSQL.
• Cloud Engineers looking to enhance their expertise in managed database services like AWS DynamoDB or Azure Cosmos DB by understanding the underlying NoSQL principles.

Prerequisites

• Basic Knowledge of Databases: A fundamental understanding of how data is stored and retrieved is recommended.
• General Programming Logic: Familiarity with basic programming concepts will help in understanding query languages and data modeling.
• SQL Knowledge (Recommended): While not strictly required, having experience with SQL makes the comparison to NoSQL much more intuitive and easier to grasp.
• No Advanced Experience Needed: This course is structured to guide you from the core concepts to advanced implementation, making it accessible to those new to distributed systems.
