You're creating a database for a small-time CRM (Customer Relationship Management) system.

1. Create a collection of customers.
2. Add a new customer with a business_name of Acme, num_employees of 1200, account_value of 50000
3. Add a new customer with a business_name of Apple, num_employees of 35100, account_value of 23000000
4. Add a new customer with a business_name of Ma&Pa, num_employees of 15, account_value of 1200

Now, practice querying for results:

1. Select all customers with an account value of greater than 10000
2. Select only names of businesses that have less than 2000 employees
3. Select all customers sorted by number of employees (ascending, or lowest to highest)
4. Select the id of customers whose business name's begin with 'A' (hint: http://docs.mongodb.org/manual/reference/operator/query/where/#op._S_where)

Let's modify some of our records:

1. Add a rep for each record in the collection:

• For Acme, rep name: 'Wile E. Coyote', employee #: 4311
• For Apple, rep name: 'Fan Boi', employee #: 1216
• For Ma&Pa, rep name: 'Jedediah', employee #: 5918

2. Update every customer to have an active status of true
3. Update Ma&Pa to have 20 employees and an account_value of 2500
4. Select the rep names of every customer
