Object–relational database

An object–relational database is a type of computer database that works with data stored in two different ways. The first way is to store the data in objects (like images, words, numbers, etc). The second way is to store the data in relationships (like how objects are connected to each other). This type of database makes it easier to keep track of information and also makes it easier to find what you are looking for.
