Understanding SQL

SQL is a query-based language used to manage, organize, and retrieve archived data from a computer database. The DBMS processes the SQL query, obtains the needed information, and gives it back to us. Instead, SQL statements specify what data should be taken or added to the database, as well as organized.

SQL's Brief History

• Dr. Edgar F. "Ted" Codd invented SQL  in 1970, as a relational database paradigm. 

• In 1986, IBM created a relational database prototype that was standardized by ANSI (American National Standards Institute).

• Window functionalities, XML-related functionality, and other enhancements were added in 2003.

• Various adjustments included XML query language support (2006), better temporal database support (2008), data types, isolation levels, logical operators, syntax, and so on. 

• The revision names include the year of creation, for example, SQL 2008, SQL 2011, SQL 2016, and so on.

SQL Fundamentals

SQL is a popular query language for managing relational databases such as MySQL Database, Oracle, and others. It is made up of the following sub-languages for performing various operations:

• (DDL)Data Definition Language: The commands needed to define the data are included.

• (DML)Data Manipulation Language: After obtaining raw data, it must be overseen and transformed into properly structured tables. DML is in charge of this.

• (DCL)Data Control Language: Because the data is generated in large quantities and manipulated using simple commands of Data Manipulation Language and Data Description Language, simple operations can be performed on them

• (TCL)Transaction Control Language:  allowing for the building of relationships with many clients

• (DQL)Data Query Language:  the required data is displayed to the user while the original and authorised data is stored in a database management system.

Uses of SQL for Data Analysis

• Finance: used to manage financial data, such as stock market data, customer account data, and loan information.

• Retail: used to manage inventory data, customer purchase data, and sales data.

• Healthcare: used to manage patient medical records, insurance claims and clinical trial data.

• Logistics: collect shipping data, inventory data, and transportation data.

• Manufacturing: manage production data, inventory data, and quality control data.

• Telecommunications: manage customer and network data, and call detail records and so on.
