Whenever there is a comparison of GDPs amongst the countries, Purchasing Power Parity (PPP) concept is very vital to understand. Gross domestic Product (GDP) represents an accounting of the total value of all final goods and services produced in a geographic region over a specific period of time, usually one year.
From Wikipedia, the free encyclopedia. A globally unique identifier (GUID, /ËÉ¡aÉªd/ or /ËÉ¡uËÉªd/) is a unique reference number used as an identifier in computer software. The term GUID typically refers to various implementations of the universally unique identifier (UUID) standard.
In this case, the unique identifier is in the âItem Codeâ column. Note: For the VLOOKUP function to work with a database/list, that list must have a column containing the unique identifier (or âkeyâ, or âIDâ), and that column must be the first column in the table. Our sample database above satisfies this criterion.
