This self-paced course offers a comprehensive introduction, guiding you through the entire lifecycle of data warehousing – from design and deployment to loading, management, and querying. It doesn’t just stop at the repositories; you’ll also get hands-on experience with BI tools to analyze the data stored within them.
The journey begins with a foundational module that clearly distinguishes between various analytics repositories like data marts, data warehouses, data lakes, data lakehouses, and data reservoirs. You’ll learn about their unique functions and use cases, understanding how each contributes to an organization’s data strategy.

The second module delves into the practicalities of designing, modeling, and implementing data warehouses. You’ll explore enterprise data warehousing architecture, understand the relationship between data cubes and star schemas, and master techniques like slicing, dicing, drilling up/down, rolling up, and pivoting. The benefits and applications of materialized views are thoroughly explained, alongside the organization of data using facts and dimensions. The module also covers normalization for snowflake schemas, populating warehouses, incremental updates, data verification, querying, and the practical application of CUBE and ROLLUP options. The importance of staging areas is also highlighted.
For those eager to see data in action, the ‘Data Warehouse Analytics’ module provides hands-on experience with IBM Cognos Analytics. You’ll learn to create visualizations, build interactive dashboards, and explore advanced features, transforming raw data into actionable insights.
The course culminates in a final assignment and quiz that cleverly integrates all the learned concepts. You’ll have the opportunity to design and load a data warehouse, write aggregation queries, create materialized query tables, and finally, build an analytics dashboard using IBM Cognos. This practical application solidifies your understanding and provides a tangible project to showcase.
Overall, ‘Getting Started with Data Warehousing and BI Analytics’ is a well-structured and informative course that effectively bridges the gap between theoretical concepts and practical application. Whether you’re a student, a budding analyst, or a professional looking to upskill, this course provides a solid foundation for a successful career in data warehousing and BI.
