Unlike relational databases, where a foreign key constraint denotes only that multiple rows are related, relationships in Neo4j are first-class entities. Neo4j’s native graph storage architecture makes your social network application extremely fast by not forcing intermediate indexing at every turn. Unlike relational databases, Neo4j stores interconnected social data that is neither purely linear nor hierarchical.

Graph databases are both easy and quick at traversing relationships, and they return instantaneous query results. Likewise, other types of NoSQL databases struggle to handle high degrees of relatedness. These particular queries bring most relational databases to their knees. Navigating a social graph and understanding both individuals and their relationships required complex and deep queries. Your social network application must be able to process data relationships as quickly as it processes individual data entities. When you’re striving to understand user behavior in social networks, relationships between users are as important as the individual users themselves. Social networks are densely connected and become more so over time, requiring you to parse this relationship data quickly for better business insights. If you would like to learn more about the openCypher initiative and how it benefits developers, checkout the FAQ page on their website.Social media networks change and evolve quickly, so your application must be able to detect early trends and adapt accordingly. Some of these companies include Oracle, Databricks (the company behind Apache Spark), Tableau, and Linkurious. There are several companies supporting the openCypher initiative.

Cypher reference documentation: Reference documentation for versioned releases of Cypher, includes the user documentation describing use of the Cypher query language with examples and tutorials.

Technology compatibility kit: The Technology Compatibility Kit (TCK) consists of tests that software vendors can run on their products, to self-certify support for a given version of Cypher.

The first planned deliverable is a parser that will take a Cypher statement and parse it into an AST (abstract syntax tree) representation.

Reference implementation: A reference implementation, distributed under Apache 2.0 license, is a fully functional implementation of key parts of the stack needed to support Cypher inside a data platform or tool.

A full semantic specification is also planned as a part of the openCypher project.

Language specification: Licensed under a Creative Commons license, the Cypher language specification is a technical expression of the language syntax to enable parsers to auto-generate the query syntax.

Technology providers can implement Cypher inside of their tools and platforms. The goal of openCypher is to accelerate the usage of graph processing and analysis by making it easier for storage, analytics or tooling platform for data access to graph data models. There is currently no common query language standard for working with Graph databases like we have SQL for accessing data in Relational databases. OpenCypher is based on Cypher, Neo4j’s query language used to store and retrieve data in the graph database. Neo Technology, the company behind the graph database, announced last week at GraphConnect Conference, the launch of the open source project that will be available to technology providers as a common language for querying graph data. Neo4j graph NoSQL database team launches open source graph query language called openCypher.
