I've two shapefile of one place. But they are not compatible. Actually when I add both of them into arcmap at the same time, there are difference between objects such as roads, parcels and etc. What is problem and how I can fix it?
Under the Editing Tools, you can find a Conflation Toolbox. These tools only work with linear features or Polylines. I would test Generate Rubbersheet Links and Rubbersheet Features. Conflation is a technique to match one feature class to another feature class. It is slightly different than just snapping. You need an Advanced License to execute the Conflation tools.
