What do you like best?
The power of this NoSQL database is amazing, also it is very easy to manage with different tools, the content on the internet is huge and also the comunity. Also it is very easy to install. The docummentation is pretty easy to find and have a lot of content to dig and take more advantage of the program.
What do you dislike?
Tools to manage your data are not as advanced or good as you can imagine, or maybe we are used to use other apps. There are security aspects that are more than a pain, because when configurating or giving access to users you will hit with some problems or things that you must do but you didn't know or are not explained very well.
Recommendations to others considering the product
Try to understand every aspect of the product, if you have a huge database it is important (or I recommend) that get knowledge about the NoSQL aspects so you can take more from it.
What business problems are you solving with the product? What benefits have you realized?
Data storage and backups, we had problems with our server and almost lost everything, so this was a good workaround. It is super stable, scalable and a powerfull tool.
