A better SQL in 11 lines of code

Prela is a new query language developed at UCLA that simplifies database queries using binary relations (two-column tables) and function composition principles, allowing complex queries to be written in just 11 lines of Python instead of 20+ lines of SQL. The language leverages the mathematical concept that relations are generalizations of functions, enabling more intuitive and composable query operations. By decomposing multi-column tables into binary relations and using relation composition as its core operator, Prela makes database queries more concise and easier to understand.
