database: illustra, ingress

hi.

hope u can help me.

i want to workout crossover points on a graph.

the graph has multiple lines.
and the starting information is the points (pnt) values (x,y)

from this i want to create a second table that will hold the line segments.  the sql must work out the line segments(Lseg) from the point values.

from this i would need to work out the crossover points, and wich lines are crossing over.

in addition to this i would like the databas eto shoe some robustness, in terms of y/x, when x=0. it should be able to to handle this.

thanx in advance for any help.
