Network Analysis Network analysis is commonly used for the analysis of moving resources from one location to another through a set of interconnected features. It includes determination of optimum paths using specified decision rules.
Network Analysis - How does a school system determine school bus routes and schedules?
One of the most far-reaching applications of GIS is in network analysis.
Network Analysis is a range of techniques employed by engineers and planners to study the properties of networks including connectivity, capacity, and rates of flow.
Network models are based on interconnecting logical components, of which the most important are:
"Nodes" define start, end, and intersections
"Chains" are line features joining nodes ...

Many applications of graph theory exist in the form of network analysis. These split broadly into two categories.
Most GIS users are familiar with network analysis that accepts starting and ending locations and then determines the best route between the two points along a road network.
Modeling: Applying structured rules and procedures to one or more spatial database overlays to conduct spatial and/or network analysis to derive new information to aid in problem solving and planning.

Connectivity - A topological relationship that occurs when arcs are connected using shared nodes. Connectivity is used for network analysis in geographic data processing. See also Topology.
In the same time these lines are often crossing only in projection on the plane, but not in reality (e.g. multilevel crossings). In such cases the explicit topology storage is the only way that enables the network analysis.
