Can you please elaborate on the five fundamental SQL commands that every database user should be familiar with? Understanding these basics is crucial for managing and manipulating data in a relational database system. I'm particularly interested in how these commands are used to retrieve, insert, update, and delete information from a database. Additionally, could you provide brief examples of each command to further clarify their application?
