EDUCATION
Diamond color is all about what you can’t see. Diamonds are valued by how closely they approach colorlessness – the less color, the higher their value. (The excep on to this is fancy color diamonds, such as pinks and blues, which lie outside this color range.) Most diamonds found in jewelry stores run from colorless to near-colorless, with slight hints of yellow or brown. GIA’s color-grading scale for diamonds is the industry standard. The scale begins with the le er D, represen ng colorless, and con nues with increasing presence of color to the le er Z, or light yellow or brown. Each le er grade has a clearly defined range of color appearance. Diamonds are color-graded by comparing them to stones of known color under controlled ligh ng and precise viewing condi ons.
Why does the GIA color grading system start at D?
Before GIA developed the D-Z Color Grading Scale, a variety of other systems were loosely applied. These included le ers of the alphabet (A, B and C, with mul ple A’s for the best stones), Arabic (0, 1, 2, 3) and Roman (I, II, III) numerals, and descrip ons such as “gem blue” or “blue white.” The result of all these grading systems was inconsistency and inaccuracy. Because the creators of the GIA Color Scale wanted to start fresh, without any associa on with earlier systems, they chose to start with the le er D—a le er grade normally not associated with top quality. whereas database mangement system in SQL -whereas database mangement system in SQL

Data analysis is an important part of both scien fic research and business, where demand has grown in recent years for data-driven decision making
Analysis refers to dividing a whole into its separate components for individual examina on. Data analysis is a process for obtaining raw data, and subsequently conver ng it into informa on useful for decision-making by users. Data is collected and analyzed to answer ques ons, test hypotheses, or disprove theories.
