What is Query?

In computing, a query is a specific request for information retrieval using a database or computer system. Queries can be entered into many types of computing platforms or databases, and are used both publicly and privately by retail users, enterprises, governments, and other constituents. As they relate to blockchain systems and computing, queries are often carried out through decentralized indexing and querying platforms that make use of a graph. Graphs are an abstract data type that is designed to make use of undirected graphs and directed graphs through the mathematical field of graph theory.
