SQL
SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.
Queries
A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.

VIEW:
- The “VIEW” in Structured Query Language (SQL) is a virtual table that does not exist physically.
- It is formed by a SQL statement that links one or more tables.
- The view is considered as a derived table because the data comes from one or more base tables.
- It is a logical representation of table; all the operations asked by the user on a view are really done on the underlying base table.
- View provides security to the tables in database.
