Observable changes occur. • puts("hello world"); • LaunchRocket(); • x = 4; ## • Calculations - Depend only on their inputs and not when or how often they are called. Calling them with the IsEven) ## • Data - Unchanging records of events. Used as inputs to calculations and actions. Record the results of calculations and actions. • $ \{2, 4, 6, 8\} $ • struct Name { std::string First; program was written • Performing an action has consequences • Affect how a program executes ## • Calculations • Reliable, a calculation always produces the same resulting data when given the same input data

system for measurement, the geography data type which uses a geodetic coordinate system, with calculations on either a sphere or spheroid. The newest family member of the PostGIS spatial type family is constructing your query: is there a spatial index you can make use of; and, are you doing expensive calculations on a large number of geometries. In general, you will want to use the "intersects operator" type is a plane. The shortest path between two points on the plane is a straight line. That means calculations on geometries (areas, distances, lengths, intersections, etc) can be calculated using cartesian

type is a plane. The shortest path between two points on the plane is a straight line. That means calculations on geometries (areas, distances, lengths, intersections, etc) can be calculated using cartesian that calculations on geographies (areas, distances, lengths, intersections, etc) must be calculated on the sphere, using more complicated mathematics. For more accurate measurements, the calculations must you do not specify an SRID, the SRID will default to 4326 WGS 84 long/lat will be used, and all calculations will proceed using WGS84. Once you have created your table, you can see it in the GEOGRAPHY_COLUMNS
