Topic Question:

Describe the applicability of NoSQL to a graph database

Discussion Post:

In order to understand how NoSQL applies to graph database, one must understand what each was created for. NoSQL or Not-Only-SQL was created to deal with large unstructured data.

No-SQL allows data to be stored schema-less and not in a table format while being comparable with various languages such as java, C++, etc. NoSQL has four main database formats which are Key-value store, column-store, document, and last of all graph Database.

Graph Database allows data to be stored in a graph format without creating a hierarchical relationship between the data. The data allows direct mapping to each other instead of creating sub tables.

Having described the function of NoSQL and Graph Database, we can deduce that combining the two allows large unstructured data to be better organized in its natural state or format.
