I. Key Test Coverage Areas:
This exam assesses your knowledge across several critical areas. Don't worry, we'll break it down into manageable chunks.
A. Data Modeling & Relational Databases (Approximately 25-30 Questions)
- Relational Database Concepts: Think schemas, tables, keys (primary, foreign, candidate!), relationships (one-to-one, one-to-many, many-to-many). You'll need a solid grasp of these fundamentals. Imagine building with Lego – each piece (table) needs to connect correctly to create a stable structure (database).
- Normalization: This is all about organizing data efficiently to minimize redundancy. It's like tidying up your closet – you don't want duplicate items taking up unnecessary space.

- ETL Processes: Extract, Transform, Load – the lifeblood of any data warehouse. You'll need to know how to get data from various sources, clean it up, and load it into the warehouse. I remember spending hours on this part during my own prep – it’s worth the effort.
- Data Mining & Analysis: This is where you'll uncover hidden insights. Think trends, patterns, and correlations. It’s like being a detective, solving the mysteries hidden within the data.
