Snowflake course in Pune

About the snowflake course in Pune

Snowflake ETL refers to the process of extracting, transforming, and loading data into the Snowflake data warehouse. Snowflake is a cloud-based data warehousing platform that offers scalable storage and processing capabilities for handling large volumes of data.

Snowflake's architecture is designed to separate storage and compute, allowing for elastic scalability and performance optimization. This architecture enables Snowflake to handle large volumes of data and provide fast query response times, making it suitable for ETL processes involving massive datasets.

• TYPE3 SCD 

ETL Tool Implementation and Testing Concepts :

Basic Concepts In Sql (Select, Update, Insert and Delete) :

How  to design frequently used testing queries to validate the data in source and target for both of the reasons Data Quality and Correctness to ensure that expected data came into the final and mediator target tables or not.
