48. Points and Key Take-Aways
Conclusion

49. Conclusion
Take advantage of MongoDB Atlas!
There isn’t a one size fits all solution to a NoSQL data model.
MongoDB APIs are the same (sort of) between drivers and tools.
The MongoDB Node.js driver is not framework dependent.
Realm is a valid alternative to the Node.js driver.
