I'm currently taking the UC Davis/Coursera ArcGIS certification program and have encountered an issue I can't find mentioned elsewhere. I need to define a relationship between a feature class and a data table, but when right clicking on my database and selecting "new", there is no option for creating a relationship class.
EDIT: When searching for "relationship classes" and navigating to the relationship class toolbox it appears that I don't have the proper license to execute the selected tool. If anyone knows how to create a relationship between a feature class and a data table some other way, guidance would be appreciated.
I'm running ArcMap 10.6 and so far have not encountered any other issues with missing features. Screenshots below.
Any help would be greatly appreciated!
