Cypher was originally intended to be used with the graph database Neo4j, but was opened up through the openCypher project in October 2015. [ 3 ] The language was designed with the power and capability of SQL (standard query language for the relational database model ) in mind, but Cypher was based on the components and needs of a database built ...
Neo4j is a graph database management system (GDBMS) ... As of version 2.0, indexing was added to Cypher with the introduction of schemas. [21] Previously, indexes ...
Cypher Query Language (Cypher): a graph query declarative language for Neo4j that enables ad hoc and programmatic (SQL-like) access to the graph. [48] GQL: proposed ISO standard graph query language; GraphQL: an open-source data query and manipulation language for APIs. Dgraph implements modified GraphQL language called DQL (formerly GraphQL+-)
The first release of software implementing the protocol occurred in December 2015, as part of a milestone release of Neo4j Server. [2] In April 2016, Neo4j Server 3.0 was released and contained the first server implementation of the protocol, accompanied by a suite of Bolt client drivers.
Gremlin is a graph traversal language and virtual machine developed by Apache TinkerPop of the Apache Software Foundation.Gremlin works for both OLTP-based graph databases as well as OLAP-based graph processors.
A number of modes of operation have been designed to combine secrecy and authentication in a single cryptographic primitive. Examples of such modes are , [12] integrity-aware cipher block chaining (IACBC) [clarification needed], integrity-aware parallelizable mode (IAPM), [13] OCB, EAX, CWC, CCM, and GCM.
In cryptography, a Feistel cipher (also known as Luby–Rackoff block cipher) is a symmetric structure used in the construction of block ciphers, named after the German-born physicist and cryptographer Horst Feistel, who did pioneering research while working for IBM; it is also commonly known as a Feistel network.
The four-square cipher is a manual symmetric encryption technique. [1] It was invented by the French cryptographer Felix Delastelle.. The technique encrypts pairs of letters (digraphs), and falls into a category of ciphers known as polygraphic substitution ciphers.
