This is a very important aspect of software testing phase and students will be enlightened about the need of Data Warehousing. Furthermore, students will be introduced to the concepts of ETL, OLAP and OLTP systems along with a holistic description of the Data Warehouse architecture. Operational Data Store (ODS) also happens to be a very important part of this course and Data Marts are also introduced.
Dimension Modelling holds a very strong relevance in the field of software testing. Few more concepts which are covered under this ETL Testing program are Snowflake Schema, Star Schema, Dimension table, fact table, De-Normalization and Normalization.
