1CATEGORIES OF NOSQL DATABASES
1. List and discuss four basic categories of NoSQL databases
There are four basic categories of NoSQL databases which are categorized as shown:
Key value store–It consisted of big hash table of keys as well as standards.
Document based store- It is stored of documents which are completed up of tagged
basics.
Column based store- Each of the storage space block is contained data as of one
column.
Graph based – The network database is used boundaries as well as nodes for
representing as well as storing of data (Eshtay, Sleit, &Aldwairi, 2019).
2. Difference between categories and provide examples
Key value store NoSQL database: The examples of this NoSQL database are Riak
and Amazon S3. The schema less format of this input value database such as Riak is
required for storage requirements.The key values are used hash table anywhere there is
existence of exclusive key as well as indicator to specific piece of data. The bucket is
such logical group of keys excluding they are not actually grouping the data (Chen&Lee,
2019). In order to interpret a value, there is required to identify key as well as bucket as
real key is hash (key + bucket).
Document store NoSQL database: This type of data is such a compilation of key
value pairs which are consisted document store as same as key value store. The
differentiation is that the ethics are recorded and provided structure as well as encoded
managed data. Apache as well as CouchDB are examples of the document store.
JavaScript is such a query language by means of MapReduce as well as HTTP. The
