With the above assumption, we can manipulate the spatial object only to operate on ROs. For manipulating
ROs, we need three groups of operations. The first group of operations contain Insert, Split and Delete, which are
fundamental operations on ROs. The Insert operation takes a RO and a RPO as operands. The Delete operation
takes a RO and the identifier of a RO as operands and removes the object from the RO if it doesn’t violate certain
integrity constraints. The Split operation can be divided into three sorts, i.e., divides a RPO-line into its
sub-RPO-line, divides a RPO-plane into its sub-RPO-plane, and divides a RPO-solid into its sub-RPO-solid. The
second group of operations support the management of two-way linking between ROs and components of spatial
attribute values in the database, such as Register, Unregister and GetRO, etc. Here Register informs a RO roid (i.e.,
RO identity) to a spatial component scid (i.e., spatial component iden
