The graph data model can be implemented by NoSQL graph databases. In this paper, eight well-known NoSQL graph databases are compared to study their properties. After rigorous review of different research works which are focused on different parametric measures of storage and access, only the ...
“ A graph is a pictorial representation of a set of objects where some pairs of objects are connected by links. It is composed of two elements - nodes (vertices) and relationships (edges). Graph database is a database used to model the data in the form of graph. In here, the nodes...
Most NoSQL systems areaggregate-oriented, grouping the data based on a particular criterion and the database type (such as document store, key-value pair, etc). This model provides only simple, limited operations and only forms one dedicated view of your data. Focusing on one aggregate at a...

Traditionally classified as a type of NoSQL database, graph databases exist in several types, such as triple stores, for example. This type of database uses a special index that stores information about nodes, edges and the relationships between them in groups of three. A triple, which is ...
The global graph database market size was valued at $651 million in 2018, and is projected to reach $3,731 million by 2026, growing at a CAGR of 24.5%
GraphQL 跟用作存储的 NoSQL 没有必然联系,虽然 GraphQL 背后的实际存储可以选择 NoSQL 类型的数据库,但也可以用 SQL 类型的数据库,或者任意其它存储方式(例如文本文件、存内存里等等)。 GraphQL 最大的优势是查询图状数据。GraphQL 是 Facebook 发明的,我可以用 Facebook 做例子。例如说,你要在 Facebook ...
