What is the difference between a "Feature Class" and an "SDE Feature Class"? Or a "Table" and an "SDE Table" that are hosted on the same enterprise gdb with the same direct connection. The attached screenshot below, shows my direct connection to an Oracle GDB. In the "Type" column on the right, you can see "Feature Class" and "SDE Feature Class". What is the difference between these two?
Also, in the attached ArcCatalog screenshot below are two line feature classes. Their icons are different. Why are different icons signifying?
In the second screenshot, the second feature clase: GIS_PUBLIC.STREETLINE is a view. The icon is the view one.
And also all the "Feature Class" layers in your first screenshot, with the same icon.
