What is SQL? 

Rapid changes in the creation and use of data has brought about significant shifts how we store data. Previously all essential information was stored in a filing cabinet, the system and content varied greatly but access remained the same. However, to find required data swiftly and easily it is of great benefit to understand the system and protocol used to organise the cabinet!

In 2021, the world relies on databases. From small business's storing customer records, to Government and multinationals managing huge amounts information, data is collected and stored digitally. To access and utilise this digital data requires a new set of skills. We need to learn how to communicate with data storage systems for so we can find the information we are looking for. That is where SQL comes in. Structure query language (SQL) is a code language that allows users to communicate with databases.

Constructed by developers using code, these databases are not simple to navigate let alone use effectively. Instead, users need to speak the language of the data warehouse to get the answers they need. Using SQL anyone can request data, filter, and pull only what you need from across multiple data tables. Through use of this specific language creating, editing, merging, or deleting tables is made simple. 

Why learn SQL?

 
90% of all data today was generated in the last three years. Big data rules start-ups and in tech, data is king. However, increasingly this can be said for all industries and organisations, big and small. There is now an expectation to use a firm’s unique data to make informed business decisions and to better understand customers. From healthcare and government to marketing and finance, no matter the industry the better you can access and use data the better the chances of staying ahead, seeing growth, and finding new ways to innovate. 

As a result, SQL is a language you should learn regardless of your domain. The better you can communicate with a database and know how access data, the more you can use data in your job. The more data, the better informed you are and the better you can be at your job regardless of industry or position!

SQL is an accessible and easy to learn language. It provides a fantastic foundation for other coding languages, offering a great starting point for those looking to begin their learning in this area. With powerful features and simple troubleshooting, learning SQL has clear benefits for individuals and workplaces alike.
