SELECT title, director FROM movie WHERE release_year=1994 This means that even non-programmers can figure out the meaning of some simple SQL queries. Although SQL requires a strict syntax, or order of words and commands, it is designed to be human readable. IBM invented SQL, or Structured Query Language, in the 1980s as a way to communicate with databases. That’s where our guide to SQL proceeds to the notion of a programming language. In order to access data in a database, however, you need to specify what you want to see. When you open an Excel sheet, you can see all the data right away. Below is an example of a very simple table in a database. A database is a set of tables that look similar to Excel sheets – they consist of columns that always store one kind of data and rows that hold information about specific items.
In a spreadsheet, there are columns and rows which you can fill with data. You have probably used a spreadsheet program (like Excel). Some popular DBMS programs are Oracle, PostgreSQL, MySQL, Microsoft SQL Server, and SQLite. A DBMS can configure a database as well as add, delete, and display data. Going further with our guide to SQL, a database management system (or DBMS) is a computer program, just like an Internet browser or a word processor. SQL Fundamentals: Database Management System
