The data model is an associative array, more commonly known as a dictionary, map, or hash table. A model is a collection of records or objects, with each record identified by a unique key. Some key-value datastores support some ordering of the keys. Graph databases may be the most complex of the common NoSQL styles of database to understand, but when applied to the right problems there can be no doubting the effectiveness they can deliver in NoSQL databases do not have a schema in the same rigid way that relational databases have a schema. Each of the four main types of NoSQL database has an underlying structure that is used to store the data. If you have worked with any of these databases or any other NoSQL database, let me know in the comments section below. I would love to hear about your experience!

Non-relational NoSQL-type databases have been around since the 1960s, but it wasn’t until the early 2000s that the NoSQL approach started to have broad appeal and a new generation of NoSQL systems began to hit the market. A NoSQL database sets no limits on the types of data you can store together, and allows you to add different new types as your needs change. With document-based databases, you can store data in one place without having to define what “types” of data those are in advance.
