Categories of NoSQL Database
There are four categories of NoSQL databases. All the categories are explained below
stating their different with each and examples where the storages are used.
1. Key Value store database- The key value store is considered as the simplest of the data
stores where the client or the user can get the key value, assign a particular key value or delete a
value of the key from that data store (Haseeb & Pattun, 2017). In this data store, the
responsibility is on the application to know what type of value is stored. Access of primary key is
always used by the data of key value. This particular data store have great performance and can
be scaled as per the need of the v-business.
Examples where this data storage can be used are
 For storing the data of user session
 Maintaining a user profile that does not have schema
 Storing the preferences of the user
 Storing the data of a shopping cart
The databases like Redis, Riak, and MemcacheDB uses the concept of key value data
storage.
2. Document Store database- The data store of document NoSQL is same as the key
value database. This data store also stores key and a value (Chandra, 2015). The only difference
with the key value storage is that this data storage is document base and the value in this data
storage contains some structured as well as semi-structured data. This value is mainly referred as
a document and can be indifferent formats such as JSON, XML, and BSON.
