Data Modeling

Architecting Data for Analysis

Effective analysis starts with a solid data foundation. I specialize in designing data models that are optimized for reporting and analytics. This involves understanding the relationships between different data entities and structuring them to minimize redundancy and maximize query performance.

I frequently utilize Star Schema designs in Power BI, creating clear distinctions between Fact tables (transactions) and Dimension tables (context), which simplifies report building and ensures accurate results.

Key Competencies

• Star Schema and Snowflake Schema Design
• Entity-Relationship (ER) Diagrams
• Data Normalization and Denormalization
• Defining Relationships (One-to-Many, Many-to-Many)
• Data Integrity and Quality Assurance
