The importance of a database relies in saving information to benefit from retrieving, processing, hiding, declaring them depending on necessitous. In this research, information represents the coordinates of different curve points, these curves are path for aircraft on air or railway or launch of rocket path or tunnel or tracing path in desert and many of important paths ,all can be considered as curves, these curves have been taken and saved as binary images then begin to search for the beginning point of this curve (the point with different color that have only one neighborhood ) ,saving this point in a database that have been constructed for this purpose ,then changing the point color to be the same as the background ,continuing tracing the curve points until the end zone (that have no neighborhood ) to have a database to be benefit from it in security operations by hiding important paths(military tunnel, oil pipe) knowing only to those owning the related database.
