In the simplest case, a Relationship row describes exactly one version-to-version relationship. If Z_OrgVS_Z = Z_OrgVE_Z, then the range of origin versions contains exactly one item. Similarly, if Z_DstVS_Z = Z_DstVE_Z, then the range of destination versions contains exactly one item. If both these equalities hold, the row describes exactly one version-to-version relationship. For example, if a row has the following values, it indicates that there is a version-to-version relationship between a version of the object whose internal ID is 7 and a version of the object whose internal ID is 888.
OrgID = 7
Z_OrgBrID_Z = 1
Z_OrgVS_Z = 3
Z_OrgVE_Z = 3
DstID = 888
Z_DstBrID_Z = 4
Z_DstVS_Z = 2
Z_DstVE_Z = 2
RelTypeID = 465
Z_RelFlags_Z = 2
