Introduction to Big Data Modeling and Management Systems

As the volume and variety of data grow, traditional databases often struggle to keep pace. Understanding how to structure, store, and manage massive datasets is a critical skill for anyone looking to work in modern data environments. This text-based course guides you through the foundational concepts of big data architecture. You will move from basic terminology to designing scalable data models, preparing you to choose and implement the right storage solutions for structured, semi-structured, and unstructured data. What you'll learn: - Understand the core characteristics of big data and how they impact storage and processing requirements. - Compare traditional relational databases with modern NoSQL systems, document stores, and key-value databases. - Design data models optimized for semi-structured data formats like JSON and XML. - Explore modern data lakehouse architectures and schema-on-read modeling strategies. - Learn the fundamentals of vector databases and how they manage unstructured data for modern AI applications. - Apply data partitioning and indexing techniques to optimize query performance in distributed environments. The course begins with essential terminology and the evolution of data management systems. You will then progress through written explanations, practical query design examples, and conceptual exercises that reinforce how to structure data for real-world analytical needs. This course is designed for beginners, data enthusiasts, and aspiring database administrators. No prior experience with big data systems is required.
