Structured Query Language is a standard language for databases that create, update, and get information from a relational database. Here are some exciting things you should know about SQL. SQL doesn't care about the case. But it is best to use keywords (like SELECT, UPDATE, CREATE, etc.) in capital letters and user-defined things (like table name, column name, etc.) in small letters. We can write comments in SQL by putting a "-" (double hyphen) at the beginning of any line.

SQL is the programming language for relational databases, such as MySQL, Oracle, Sybase, SQL Server, Postgre, etc., which are explained in more detail below. Other databases that don't use SQL, like MongoDB, DynamoDB, and so on, are called NoSQL databases. Even though SQL is based on an ISO standard, the syntax of most implementations is a little different. So we might run into queries that work in SQL Server but not MySQL.

For managing data stored in a relational database management system (RDBMS) or for stream processing in a relational data stream management system, programmers utilize SQL (Structured Query Language) (RDSMS). It is especially helpful when managing structured data or data that includes relationships between entities and variables.

Good overview of SQL languages. One thing I like to poll people on is a divisive topic around SQL. Some argue that SQL, while a query language, is not a program language. Others argue the opposite that it is a program language. Now that you're armed with knowledge on what SQL is, which side would you take and why?
