Types of Tables:
Fact Constellation Schema
SCD ( Slowly Changing Dimensions )
Different types of SCD’s which developer develops and a tester has to test as per different types of data needs of clients
We implement SCD-1 and SCD-2 in class to show the implementation part more transparently and explain SCD-3 to define how to work on limited historical data as well which is used sometimes
• TYPE1 SCD
• TYPE2 SCD
• TYPE3 SCD
ETL Tool Implementation and Testing Concepts:
Basic Concepts In Sql (Select, Update, Insert and Delete)
