How to generate attributes using attributes from two datasets (sources)
Hello! I am new with rapidminer, and i am taking the first steps with ETL processes. Now, i have found a problem that i don't know how to solve it. In particular, I am looking for a way to generating new attributes applying function expressions where I need to use attributes from two database tables (dataset1, dataset2), where one of the tables (dataset2) has attributes that i need to use to calculate new attributes in the other table (dataset1).
Tables have different number of rows, and need to calculate a particular value of att1 in dataset1 to apply as a constant to calculate new attribute.
