Basically Structured Query Language (SQL) is the standard and most widely used programming language for relational databases. It is used to manage and organize data in all sorts of systems in which various data relationships exist. SQL is a valuable programming language with strong career prospects. The main use is it can be used to share and manage data, particularly data that is found in relational database management systems, which include data organized into tables. Multiple files, each containing tables of data, also may be related together by a common field. Using SQL, you can query, update, and reorganize data, as well as create and modify the structure of a database system and control access to its data.
Scopes in SQL :
- Database administrator (DBA): This is someone who specializes in making sure data is being stored and managed properly and efficiently. Databases are most valuable when they allow users to retrieve desired combinations of data quickly and easily.
- Database migration engineer: This person specializes in moving data from various databases onto an SQL server.
- Data scientist: This is a position very similar to that of a data analyst, but data scientists typically are tasked with handling data in far greater volumes and accumulating it at much higher speeds.
- Big data architect: Someone in this role builds products for handling large volumes of data.
- Business Analyst: A Business Analyst helps guide businesses toward better processes, products, services, and software through business analysis. When data is of interest in the gap analysis, SQL can be used to find gaps in data such as dates or number sequences.
- Journalist: A journalist collects, investigates, writes, or distributes news or other current information to the general public. Journalists who know SQL are in demand because of their ability to rapidly analyze, organize, and filter through information.
For data analyst roles, SQL is again the most in-demand skill, listed in 70% of all data analyst jobs. SQL appears in 1.5 times as many “data analyst” job postings as Python, and nearly 2.5 times as many job postings as R. There’s no doubt that if you’re looking for a role as a data analyst, learning SQL should be at the top of your to-do list.
