// address model
    var addressModelSchema = new Schema({
        city: String,
        street: String,
        houseNumber: String
    })
    mongoose.model('address',addressModelSchema ,'address' )

// contactInfo model
    var contactInfoModelSchema = new Schema({
        tel: [Number],
        email: [String],
        address: {
            type: mongoose.Schema.Type.ObjectId,
            ref: 'address'
        }
    })
    mongoose.model('contactInfo ',contactInfoModelSchema ,'contactInfo ')

// customer model
    var customerModelSchema = new Schema({
        firstName: String,
        lastName: String,
        company: String,
        contactInfo: {
            type: mongoose.Schema.Type.ObjectId,
            ref: 'contactInfo'
        }  
    });
    mongoose.model('customer', customerModelSchema, 'customer')

// add new address then contact info then the customer info
// it is better to create model for each part.
