Curated list of resources and links about using NoSQL databases and things to look for when deciding to use one.
A basic definition of NoSQL databases can be found on Wikipedia as:
"A NoSQL (originally referring to 'non SQL' or 'non relational') database provides a mechanism for storage and retrieval of data which is modeled in means other than the tabular relations used in relational databases."
For actual NoSQL databases, you can go here, here, here, here, here, or here. Also, not to be confused with the relational database management system, NoSQL.
