Data Science for Construction, Architecture, and Engineering Industry

What is SQL?

SQL, or Structured Query Language, is a programming language specifically designed for managing and manipulating relational databases. It serves as a standardized method for accessing and retrieving information from databases, as well as for performing various operations such as inserting, updating, and deleting data. SQL enables users to interact with databases in a simple and intuitive manner. With SQL, users can write queries to select specific data from tables, join multiple tables together, filter and sort data, and perform calculations and aggregations. It provides a declarative approach, allowing users to specify the desired result without needing to define the exact steps to achieve it.

SQL is widely used across industries and is considered a fundamental skill for data analysts, database administrators, and data scientists. It offers powerful capabilities for data manipulation, transformation, and analysis. Additionally, SQL is supported by various database management systems (DBMS) such as MySQL, PostgreSQL, Oracle, and Microsoft SQL Server, making it highly versatile and applicable in different environments.
