HyperGraphDB - Database for Storing Strongly-Typed Hypergraphs

  •        0

HyperGraphDB is a general purpose, open-source data storage mechanism based on a powerful knowledge management formalism known as directed hypergraphs. While a persistent memory model designed mostly for Knowledge management, Artificial Intelligence and Semantic web projects, it can also be used as an embedded object-oriented database for Java projects of all sizes. It could also be used as graph database or as (non-SQL) relational database.

A P2P framework for distributed processing has been implemented for replication/data partitioning algorithms as well as client-server style computing. While it falls into the general family of graph databases, it is hard to categorize HyperGraphDB as yet another database because much of its design evolves around providing the means to manage structure-rich information with arbitrary layers of complexity.

GraphView - GraphView is a DLL library that enables users to use SQL Server or Azure SQL Database to efficiently manage graphs


GraphView is a DLL library that enables users to use SQL Server or Azure SQL Database to manage graphs. It connects to a SQL database locally or in the cloud, stores graph data in tables and queries graphs through a SQL-extended language. It is not an independent database, but a middleware that accepts graph operations and translates them to T-SQL executed in SQL Server or Azure SQL Database. As such, GraphView can be viewed as a special connector to SQL Server/Azure SQL Database. Developers will experience no differences than the default SQL connector provided by the .NET framework (i.e., SqlConnection), only except that this new connector accepts graph-oriented statements.GraphView is a DLL library through which you manage graph data in SQL Server (version 2008 and onward) and Azure SQL Database (v12 and onward). It provides features a standard graph database is expected to have. In addition, since GraphView relies on SQL databases, it inherits many features in the relational world that are often missing in native graph databases.
