Overview of Dimension Tables – Understand the purpose of dimension tables in a data warehouse and their importance in supporting analytical processes. 2. Types of Dimension Tables: o Conformed Dimension – Shared across multiple fact tables, providing consistency in reporting. o Role-Playing Dimension – Used multiple times within the same database to represent different contexts (e.g., Date dimension as Order Date, Ship Date). o Slowly Changing Dimension (SCD) – Learn the different types of SCDs (Type 1, Type 2, Type 3) and how they handle changes in data over time. o Junk Dimension – Combines unrelated attributes into one dimension table for efficient storage. o Degenerate Dimension – Derived from fact tables to provide unique identifiers without additional attributes. o Inferred Dimension – Used when certain details are unknown initially but are updated as information becomes available. 3. Designing Effective Dimension Tables – Tips on setting up dimension tables for optimal performance, reducing redundancy, and maintaining data integrity. 4. Best Practices – Techniques to enhance data warehouse performance and improve data quality using well-structured dimension tables. 👍 Enroll for GoLogica Snowflake Training 📕 Snowflake Training ➡ https://www.gologica.com/course/snowf... 📕 Why do you need to learn Snowflake? ➡ https://www.gologica.com/elearning/wh... 📕 Snowflake Tutorial Overview Updated- 2020 ➡ https://www.gologica.com/elearning/sn... 📕 The Beauty and Science of Snowflakes ➡ https://www.gologica.com/elearning/th... 📕 Snowflake vs Redshift – Which is the Best Data Warehousing Tool ➡ https://www.gologica.com/elearning/sn... 📕 Snowflake vs Databricks ➡ https://www.gologica.com/elearning/sn... 📕 Snowflake vs Hadoop: Which one is better? ➡ https://www.gologica.com/elearning/sn... ----------------------------------------------------------------------------------------------------------------------------------------------------------- GoLogica Community: https://www.gologica.com/ Instagram: :-   / gologicatechnologies   Facebook: :-   / gologica   LinkedIn : :-   / mycompany   Twitter: :-   / logica_go   📌 Subscribe to our channel to get video updates.
