I have been working on Oracle databases for more than a year. My favorite part is PL/SQL. This is Oracle's data programmable language, which can be used to combine procedural code with SQL code. The most interesting thing is that we can use it to develop the entire application in one place. All data selection and updates, all HTTP and HTML outputs that interact w
