How to apply given below data validation rules in talend. which components we can use with example. thanks
Max_length_if_not_empty Null_blank_check Invalid_pattern_check_if_not_empty Is_empty Date_Comparision Datetime_format_check_if_not_empty Valid_values_if_not_empty (in from of reference data/lookup) Valid_values_if
But: How why where? as a consultant questions are: how many times do you want to check that! is it for migration or for run are rules fix or they are going to change? do you want to add rules? what is the language of rules? where are the data in db, file, cloud? why do you want talend to do that! and some others….
Are you trying to do something like a regular data health check to increase the quality of your daily/weekly feeds or you are trying to just check the overall data health as a pre-check before a migration?
