comment How to create a Network Topology in a shapefile that contains only nodes(geometry points)?
You need to know how points are connected to each other, how their relation is to each other. Otherwise routing will not work.

comment How to create a Network Topology in a shapefile that contains only nodes(geometry points)?
Sorry, the question in the title is different than the explanation. This makes no sense. You cannot create network out of a point data, if you have no information about the relation (ways) between the points.

comment How to visualize pgrouting result?
I think it's really time to do the pgRouting workshop: workshop.pgrouting.org/chapters/wrapper.html I think I have even mentioned it already to some of your other question(s). PRetty much any of your questions is explained there.

comment How to calculate the optimum bus route using pgrouting?
Well, I would say that a bus stop is always on some street. So I would pre-process the data and split the road links where the bus stops are. So where you have one road link before you will have 2 road links afterwards. Just use a new serial ID attribute, then you can keep the old ID as well for both segments. When you run the topology function again using the new ID column, then all your stop points are nodes in the routing network.

comment from coordinates can i find from multilinestring from database
You can take a look, but this is a very very old archived website, which uses not only old pgRouting but also old PostGIS and a lot more probably. So I would be careful.
