A great circle, also known as an orthodrome or Riemannian circle, of a sphere is the intersection of the sphere and a plane that passes through the center point of the sphere.

This partial case of a circle of a sphere is opposed to a small circle, the intersection of the sphere and a plane that does not pass through the center.

Any diameter of any great circle coincides with a diameter of the sphere, and therefore all great circles have the same circumference as each other, and have the same center as the sphere.

A great circle is the largest circle that can be drawn on any given sphere.

Every circle in Euclidean 3-space is a great circle of exactly one sphere.

In differential geometry, a geodesic is a generalization of the notion of a "straight line" to "curved spaces".

The term "geodesic" comes from geodesy, the science of measuring the size and shape of Earth; in the original sense, a geodesic was the shortest route between two points on the Earth's surface, namely, a segment of a great circle.

The term has been generalized to include measurements in much more general mathematical spaces; for example, in graph theory, one might consider a geodesic between two vertices/nodes of a graph.

A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.

Distance is a numerical description of how far apart objects are.

In physics or everyday usage, distance may refer to a physical length, or an estimation based on other criteria (e.g. "two counties over").

In most cases, "distance from A to B" is interchangeable with "distance from B to A".

In mathematics, a distance function or metric is a generalization of the concept of physical distance.

A metric is a function that behaves according to a specific set of rules, and is a way of describing what it means for elements of some space to be "close to" or "far away from" each other.

A database is an organized collection of data.

It is the collection of schemas, tables, queries, reports, views, and other objects.
