WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. … WebIdeally, when SQL Server performs I/O, the data is already in the buffer pool and it does not need to go to disk. This type of I/O is referred to as logical I/O and is the most desirable because it results in the best performance. If the SQL Server data does not need to reside in the buffer pool, it will need to access disk resulting in ...

WebGeodesic buffers are those that account for the actual shape of the earth (an ellipsoid, or more properly, a geoid). Distances are calculated between two points on a curved surface (the geoid) as opposed to two points on a flat surface (the Cartesian plane). You should always consider creating geodesic buffers when.
