Abstract
A computer-implemented method, computer program product and a system for identifying and handling slowly changing dimension (SCD) attributes for use with an Extract, Transform, Load (ETL) process, comprising importing a data model for dimensional data into a data integration system, where the dimensional data comprises a plurality of attributes, identifying via a data discovery analyzer one or more attributes in the data model as SCD attributes, importing the identified SCD attributes into the data integration system, selecting a data source comprising dimensional data, automatically generating an ETL job for the dimensional data utilizing the imported SCD attributes, and executing the automatically generated ETL to extract the dimensional data from the data source and loading the dimensional data into the imported SCD attributes in a target data system.
