The callback will return an error for the first argument and the newly-created model instance for the second argument. The first argument is the singular name of the collection that will be created for your model , and the second argument is the schema you want to use in creating the model. You can require() and connect to a locally hosted database with mongoose.connect(), as shown below. The diagram also shows the relationships between the models, including their multiplicities. The multiplicities are the numbers on the diagram showing the numbers of each model that may be present in the relationship.

If you want to install a MongoDB server then you can download installers from here for various operating systems and install it locally. Once we’ve decided on our models and fields, we need to think about the relationships between them. Before you jump in and start coding the models, it’s worth taking a few minutes to think about what data we need to store and the relationships between the different objects. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite, and MSSQL and features solid transaction support, relations, read replication and more. The benefit of using an ORM is that programmers can continue to think in terms of JavaScript objects rather than database semantics — this is particularly true if you need to work with different databases . They also provide an obvious place to perform data validation.
The story was later made into several films and a song by Donovan, among other references. A mongoose is also featured in Bram Stoker’s novel The Lair of the White Worm.
