1. A method for generating a data integration scenario between a data source and a data target using a combination of a data flow extract-transform-load (ETL) and an entity relationship extract-transform-load (ETL), the method comprising:

  • receiving, at one or more computer systems, a set of extract-transform-load (ETL) entity relationships defined via a component of a logical design of the data integration scenario, the set of ETL entity relationships having a relationship defined between one or more attributes of a first entity in a dataset and one or more attributes of a second entity in the dataset;

    automatically determining, with one or more processors associated with the one or more computer systems, an extract-transform-load (ETL) data flow model using the set of ETL entity relationships, wherein the ETL data flow model is configured to provide semantic definitions for the logical design, wherein the semantic definitions define entity relationships in the dataset that identify how columns of the data target are populated from attributes of the data source and from one of the one or more attributes of the first entity in the dataset and the one or more attributes of the second entity in the dataset; and

    generating, with the one or more processors associated with the one or more computer systems, information indicative of the ETL data flow model in a view of the logical design, wherein a set of attributes are exposed to downstream components of the logical design that includes the one or more attributes of the first entity and the one or more attributes of the second entity.
