I am relatively new to geodatabases. I have been working with a file geodatabase provided by a consultant; the idea is to take this and make it our own to manage. I copied the contents of the file geodatabase into another blank file geodatabase as part of testing and learning. Now I want to clean up the geodatabase: rename features, group features, etc., so that when I pass this out to colleagues it is more succinct and intuitive, but I can't figure out how to make the edits. In ArcMap I can group and do whatever I want to the geodatabase, but the edits don't carry back to the the actual DB. I have tried working in ArcCatalog as well. Sorry, I am sure this is simple for most people on here - thanks for any help you can give me.
