1. A computer-implemented method of 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, wherein 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.
