Introduction to ETL and DW Concepts
What is Data Warehousing?
Differences between OLTP and Data Warehousing
Why we need two separate solution for real time and warehousing
How to extract data from several sources and load into same target table
How to perform transformation logics on data
How to load data into final target table
Need and usage of data marts and types of data marts
DATA WAREHOUSING LIFE CYCLE
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
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.
Overview Of Etl Tool Architecture
How ETL tool works and what is the basic need of ETL tools in the market
What are the similarities between ETL tools and SQL
Why we use ETL Tools if SQL is the only standard which any Database or Data Warehouse can use
How ETL Tools work at back end
Different ETL Tools in the market
What types of tasks tester performs on ETL for testing purpose
Informatica PowerCenter (Leading tool in the market)
Coding and testing process in different transformation rules
SAMPLE Loading from source to target
SEQUENCE GENERATOR Transformation
We provide this practice as additional benefit to you so that you can implement jobs by yourself to understand that what developers do in real time which you have to test.
