# "Nested Set": This table represents an employee list with a hierarchy tree.

# The tree is not modeled by "parent" links but rather by showing the "left"

# and "right" border of any person's "region". By convention, "l" < "r".

# As it is a tree, these "regions" of two persons A and B are either disjoint,

# or A's region is completely contained in B's (B is A's boss), or vice versa.

# See the references for more info.

# or A's region is completely contained in B's (B.l < A.l < A.r < B.r:

# B is A's boss), or vice versa.

# Any other overlaps violate the model. See the references for more info.
