Databases form the literal backbone of any form of organization. But what is a database?Any grouping or structuring of data in one or more forms can be considered a database, which refers to actual physical files and folders filled with documents about the specific organization. As technology keeps progressing and has become an integral part of the day-to-day life of our society, the concept of databases is also evolving in step with it. Nowadays, a database refers to any electronic storage software that allows data to be held in an organizationally defined structure. Broadly, databases can be categorized into:1) SQL 2) No SQL 1) SQL: Most DBMS, RDBMS, and ORDBMS use SQL (structured query language) for interaction and management of the database. It is a mature standard and is widely implemented and supported. One widely used “SQL” database product is “MySQL”. 2.) No SQL: This refers to any form of database that does not use SQL for interacting with and maintaining the database. It is not a new concept, as almost all forms of database technologies preceding the SQL Standard (and even after that) have used mostly independent (and often proprietary) techniques for interacting with and maintaining the database. But more recently, “No SQL” refers to those database technologies that differ only from “SQL"-based” databases in that they use a standardized set of processes to interact with and maintain databases without the use of the “SQL” standard. One widely used “No SQL” database product is “Mongo DB.”
