object-relational mapping

Object-Relational Mapping (ORM) is like a translator. It helps turn data from your program into a different language that can be understood by databases. In this case, the translator helps turn information from your program into data that can be stored and retrieved from a database, like MySQL or PostgreSQL. So, ORM kind of makes it easier to use the information from your program with a database.
