SQL stands for Structured Query Language. It is a programming language used to manage and manipulate data in relational databases. SQL is a standard language used by most of the relational database management systems (RDBMS), including Oracle, MySQL, Microsoft SQL Server, PostgreSQL, and others.
SQL allows users to create, update, and delete data in a database,as well as retrieve data from one or more tables in a database. SQL can also be used to create views, stored procedures, and triggers that can enhance the functionality and performance of a database. SQL is an essential skill for data analysts, developers, and database administrators who work with relational databases.
A SQL Analyst is a professional who uses SQL (Structured Query Language) to analyze data from databases, create queries, write stored procedures, and develop reports. SQL Analysts are responsible for extracting data from various sources, transforming and loading data into databases, and querying data to provide insights to stakeholders. They also work on developing and optimizing SQL scripts and creating data visualizations to help business users understand data better. SQL Analysts can work in various industries, including finance, healthcare, retail, and technology.
