Why You Should Learn SQL
First, let’s talk about the value of learning SQL. SQL (Structured Query Language) is a programming language used to manage and manipulate data stored in relational database management systems (RDBMS).
Learning SQL will help you to:
– Import, export, and manipulate data;
– Write complex queries to answer specific questions;
– Combine data from multiple tables in one query;
– Aggregate data to generate summary statistics;
– Perform data cleaning, transform, and validate data; and
– Create and modify tables, views, and indexes.
Demand for SQL Specialists
The demand for SQL specialists is high, and it’s only going to increase in the future. Companies across industries need experts who can help them collect, store, and analyze massive amounts of data.
This is where SQL specialists come in; they enable companies to extract valuable insights from their large datasets, leading to better business decisions.
SQL specialists typically earn high salaries. According to Glassdoor, the national average salary for SQL developers is $83,000 per year, and the highest-paying positions can bring in over $140,000 per year.
Additionally, those who hold advanced SQL certifications can command even higher salaries.
SQL specialists can rest assured that their skills will always be in demand. As we’ve seen, data is only going to become more important in the years to come, making SQL knowledge indispensable for professionals across industries.
Whether you work in healthcare, finance, or marketing, there will always be a need for professionals who can manage and analyze data effectively. Working in Data Analysis/Data Science
