By the end of this talk, developers should be able to:

• Access and manipulate a MongoDB database from a Javascript program by using Mongoose.
• Combine multiple Mongoose operations by using Javascript Promises.
• Validate data for storage in MongoDB by setting up Mongoose validations.

1. Fork and clone this repository
2. Create a new branch, training, for your work.
3. Checkout to the training branch.
4. Install dependencies with npm install.

there a file Mongoose model called 'student.js' in /modle/student.js , and load it from the app-students.js file located in the bin directory; that file will provide a command-line UI for performing CRUD on you new Student resource.

The 'action' methods in app-students.js have no content; you'll need to fill them up with code for doing CRUD on your new model.

The Schema of Students. Students have the following features:

• firstName - (String, required)
• lastName - (String, required)
• grade - (Number, required)
• age - (Number, Greater than or equal 18)
• city - (String)

You should ensure that only reasonable values of firstName, lastName and grade allowed to be added to the database. The age should be numbers that greater than or equal to 18.
