See Portalisaatio overview logic for background information.

Portalisaatio DB is an business oriented database.

It provides logic reasoning capabilities making your data smarter by algorithmically computing new connections to your data.

Relational databases use costly join operations to create connections between entities, but Portalisaatio DB`s connections are primary objects in the database and hence provide fast querying capabilities on the data.

Portalisaatio DB rule engine evaluates logical rules. It is based on a algorithm that is capable of inferencing over high throughput of concurrent inserts and delete operations in parallel. Its capabilities include reasoning over rdf metadata using configurable and dynamically modifiable rule sets and ontologies.

Portalisaatio DB updates rules and changes without recalculation over large datasets.

Portalisaatio DB supports custom rules as well as rule standards such as RDF Schema (RDFS) and Web Ontology Language (OWL). Using ontologies it is possible to enrich the metadata with for example equality expressions and cardinality restrictions.

Portalisaatio DB rule engine can run against all incoming metadata as well as independently for smaller datasets with their own rule sets.

Portalisaatio DB takes into account the context of search, location and the intent of queries to provide relevant search results. The technology refines data into critical information in real time.

Semantic search employ to better understand the context of a search. Is not just about simply discovering information any more, it’s about ordering the web into a coherent flow of information; how topics, themes, ideas, text, video, audio is connected and related to each other.
