Frequently asked questions
SQL stands for Structured Query Language. It is a language used to manage data in a relational database. It allows you to query, manipulate, and define the data in a relational database. It has become a standard language, which means that the language the database uses will be based on SQL despite which relational database you use. This makes it a very versatile language and an important skill to have if you work with databases or data. The language closely resembles English, making it easy for English-speakers to learn and read at a glance, even for a beginner. Statements consist of clauses, identifiers, operators, and constants. Together, you can create statements such as “SELECT customer_name FROM Purchase_Table WHERE order_number = 253”. The resulting statement is structured so a computer can read, yet also easy for English-speakers with little programming experience to understand.
