performing attribute table joins in ArcGIS online

Idea created by sirob75 on Dec 11, 2015

    I work for a government department and one of the key things our analysts want the ability to do is join their data to geographic boundaries. this has always been very straightforward in ArcGIS desktop. However, with more of our users wanting to produce interactive maps in ArcGIS online (without needing desktop), we really need the attirbute join capability to be brought into the online version. We'd also like to be able to stream open, linkable data over the internet into the online platfrom to make attribute joining far more efficient.
    Here's hoping you can make this a reality soon.
