But first, let's start from the beginning to learn all about SQL and its evolution in this technological world!
What is SQL?
But then, what exactly does SQL refer to? Structured Query Language (SQL) is a programming language for storing and processing information in a relational database. A relational database organizes data into tables, columns, and rows, making it easy to view and manage. And by using SQL statements, you will store, update, delete, search, and retrieve information more efficiently in these databases, while maintaining and optimizing their performance.
SQL has existed since the 1970s and remains a leading relational database management tool, and because of its English-like syntax, it is easy to learn. For example, you can use specific commands to add or remove rows from tables easily.
Some of the most relevant jobs with SQL are data analyst and SQL developers that use this query language to retrieve or modify data from a database quickly.
SQL Facts that Everyone Should Know!
So, as we have seen, SQL (Structured Query Language) has a fascinating history spanning several decades. We will now take a very brief look at the origins and evolution of SQL and its impact on the job market:
- Birth of SQL:SQL was invented in the 1970s and developed in the International Business Machines (IBM) laboratories by Donald D. Chamberlin and Raymond F. Boyce. It sought to create a prototype relational database management system (RDBMS) allowing users to manage and manipulate data using a standardized approach. It was initially known as Structured Query Language in English (SEQUEL).
- Evolution of SQL: SQL gained popularity in the 1980s when several vendors began implementing it in their systems. The American National Standards Institute (ANSI) recognized the SQL as a standard 1986 to ensure consistency between different database systems.
- SQL new versions: In 1992, the SQL-92 was released and was more compatible with more advanced data and query capabilities. And then, new versions such as SQL:1999 and SQL:2003 came, whose significant addition was window functions which significantly increased the expressive power of SQL, which has been extremely useful in preparing business reports, analyzing time series data and trends.
- Today's job market: SQL remains a crucial tool for anyone working with databases, as you can easily get the information from data efficiently, view updated events, monitor table and database activity, and identify specific data. The main jobs with SQL are SQL data analyst and SQL developer.
- SQL future outlook: Although this technology is over 50 years old, SQL is one of the most relevant technologies. The last version of the Microsoft SQL Server is the SQL Server 2022, the most Azure-enabled version of SQL Server yet, whose improvements are more innovative and offer greater safety and performance.
