Even though MongoDB is a schema-less DB but there is a requirement in my project where I have to map my classes to the Database objects and prefer to have the data modelling for the same. Please suggest some Data-modelling tools for MongoDB to map the DB to Classes and Objects.
I think you want to model your applications and persist your data in MongoDB. So it depends on what framework/language are you using for application.
I did a quick web search to get these ODM (Object-Document-Mapper) options recommended to work with MongoDB for some of the popular languages.
ruby
java
python
