GraphDB 9.5 offers data virtualization from tables to graphs and back
Ontotext, a provider of enterprise knowledge graph technology and semantic database engines, has released GraphDB 9.5.
According to Ontotext, with GraphDB users can turn any structured data into a uniform graph, accessing data in relational databases as a virtual graph as well as transforming and reconciling tabular data into graphs with unambiguous semantics.
With this release, all GraphDB editions now support accessing relational databases such as Oracle, MySQL, PostgreSQL, Microsoft SQL Server, IBM Db2, H2, and Dremio through a virtual SPARQL endpoint configured by R2RML or OBDA descriptor. Users can access data that is impractical to replicate into a native RDF model or perform batch transformation using a declarative language. Virtualized data is accessible through virtual repositories, which allows for strict access control.
Following the positive response to the JDBC driver for GraphDB, the new release extends this functionality with a user-friendly interface to manage the SQL views. Part of GraphDB’s Workbench, the interface eliminates the need to access the database file system and performs validations of the input SPARQL query and its binding to SQL value types. All users with read access privileges can list the currently active SQL views, and those with write can create or modify them.
Emphasizing information security, GraphDB decouples the authentication from authorization providers to support a wide range of enterprise use cases and deployment scenarios. The GraphDB 9.5 release introduces single sign-on (SSO) for transparent logging with the new authentication and authorization providers of OpenID Connect (OIDC) and OAuth 2.0.
All previous configurations are compatible, and the latest version supports the definition of a priority list of multiple authentications (HTTP Basic, Kerberos, OIDC, JWT, LDAP) and authorization (Local security database, Kerberos, LDAP, OAuth 2.0) providers.
