Virtual Reality

Virtual Reality is a fully digital experience that can either simulate or differ completely from the real world. Instead of viewing a screen in front of them, users are immersed and able to interact with 3D worlds. Apart from its popular gaming use case, virtual reality is applied in a variety of industries, such as medicine, architecture, military, and others. In order to experience and interact with virtual reality, you’ll need the proper equipment, like a pair of VR glasses or a headset. It was first used to give training to pilots, instead of sitting in planes they could control operations using the VR headset. # Types of Virtual Reality There are three main types of virtual reality used today to transform the world around us, including non-immersive, semi-immersive, and fully-immersive simulations.

It is mainly used for managing structured data where we have a relationship between various entities and variables of the data. SQL consists of various types of statements that are used to query the data stored in the databases. ## DML - Data Manipulation Language These types of statements are used for performing the CRUD operations in the database.
