You have problems with MongoDB when it comes to the point when you want to transfer data from one document to an other, cause there is now atomic way in MongoDB. The solution is to use a 2 phase commit strategy which is very error prone. The most common example is when a customer orders some products and you want to transfer the products from the storage document to your order document, so the product can not be ordered from several customers. In an RDBMS no problem. Simply start an transaction and commit at the end. In MongoDB the problem starts... cause you need to be fault tolorent and more important always consistent! These cases are rare but when you come to these use cases they are hard to solve. For me in an eCommerce system consistency is the most important part. So the next time I would choose e.g. Postgres over MongoDB.
