Hi Swetha,

Data Quality is when you verify your data and identify if the data present in the warehouse is efficient and error free. The data present in each column should have the meaning full information like it should not have null data, it should not have garbage data, complete correct data must be transformed to the target data, if all the data types are correct as per the requirement, etc.
Asking for Informatica transformations means you want to know how source target tranformations to be implemented in informatica?

Thanks and Best regards,
