SQL full form is Structured Query Language. SQL is a domain-specific language. It is used in application development language to enable a programmer to work with the data. The data is stored in a relational database. To manage this data, we have relational database management systems like SQL Server, MySQL, MS Access, etc. that use SQL as a standard database language.
Here is why it is so important:
Career demand: Before jumping on to the specific use of SQL, it is essential to know where it is a must-have and why. SQL as a language is not only one of the most sought-after skills, but also one of the most well-paying. Its easy learning curve for the language tools and RDMBS tools like MySQL, SQL Server, PostgreSQL, among others makes it relevant and useful in a lot of jobs. Most importantly, an adequate level of SQL and understanding how to play with data can help you land SQL developer, Database warehouse admin, and even data scientist jobs. Despite it being easy to learn, SQL’s use makes it a must for any organization as handling data before working on it with data science and Big Data tools mostly need simple processing.
Handling data: When it comes to the subject of data processing, or accessing data from a variety of sources, usability, and universal use, SQL is one of the best and most widely used languages. The several RDBMS tools, as well as easy to learn and deploy functions, make it the foundation stone for your data-centred studies and career. Moreover, it is easy to learn, which means anyone can pick up the skills within some time and understand what’s happening at the backend. However, being genuinely skilled at SQL is another thing as it might be easy-to-learn, use, and understand, but mastery of any subject or tool needs practice and time.
Data volume and data science: If you are starting in data science or wanting to jump into Big Data, Machine learning, or any of the advanced data jobs, knowing your SQL well can give you a huge advantage. It is a perfect stepping stone both into understanding how data works, as well as these jobs that need advanced data comprehension skills. Moreover, SQL is not just a raw, easy to use the tool, its universal use, and scalability also makes it capable of handling a large amount of data even in intricate forms. It can control and access vast amounts of data from tables and be used to manage the entire organization or company’s data.
Plays well with other tools: SQL’s function to access and load data from a variety of sources also makes it one of the friendliest tools to work with. SQL is friendly with other tools if you are working locally, on the cloud, or handling vast amounts of data in an enterprise. You can access and connect SQL to a variety of tools for different purposes. You can use SQL with advanced data handling tools like R and Python and use its connectors with other tools as well.
