The document contains 14 PL/SQL programming assignments involving writing programs to find the greatest of two numbers, determine if a number is positive/negative/zero, calculate factorials, retrieve and display employee details from the EMP table, increase salaries based on certain conditions, and more. It also includes creating procedures, functions, packages and triggers to perform various operations on database tables.
