A more than interesting concept for your software design. Therefore I wrote two examples in ABAP, inspired by the book \"Clean ABAP\".\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkeller-michael%2Fvalue_objects","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fkeller-michael%2Fvalue_objects","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fkeller-michael%2Fvalue_objects/lists"}
