Answer / Swarn Singh
Yes, Informatica PowerCenter can be used as a data cleansing tool by utilizing various transformations to clean and standardize data during the ETL process. Some common transformations for data cleansing include:n
1. Expression Transformation: This transformation allows you to write custom code (using JavaScript, SQL, or VBScript) to perform complex data validation, correction, and transformation rules.
2. Data Quality Transformations: Informatica provides a set of prebuilt transformations for handling common data quality issues such as duplicates, missing values, outliers, and inconsistent formats.
3. MatchMerger Transformation: This transformation compares records from two sources and merges or replaces them based on specified matching rules. It can be used to identify and correct duplicate records.
4. Data Profiling Transformations: Informatica offers data profiling transformations that analyze the quality of your data, providing statistics about data distribution, validity, and completeness.

HI, Anybody is having informatica Dumps,if it there Can u send to my mail id :sathesh.cool@gmail.com
you have created a lookup transformation for a certain condition which if true returns multiple rows. when you go to the target and see only one row has come and not all. why is it so and how it can be corrected.
