SQL (Structured Query Language) is a powerful tool used to perform operations on records stored in a database. These operations include updating, inserting, and deleting records, as well as creating and modifying database tables and views.
It’s important to note that SQL itself is not a database system; it is a query language. To execute SQL queries and manage your data, you need to install a database management system (DBMS) on your system. Popular DBMS options include Oracle, MySQL, MongoDB, PostgreSQL, SQL Server, and DB2
What is SQL?
SQL stands for Structured Query Language, pronounced either as S-Q-L or See-Quell.
This database language is primarily designed for managing data in relational database management systems (RDBMS). It is a specialized tool used by data professionals to handle structured data, which is stored in table format. Additionally, SQL is designed for stream processing in RDBMS.
With SQL, you can easily create and manipulate databases, as well as access and modify table rows and columns. This query language was established as an ANSI standard in 1986 and an ISO standard in 1987.
If you’re aiming for a career in data science, SQL is an essential query language to learn. Major enterprises like Facebook, Instagram, and LinkedIn use SQL to manage their backend data.
