Incremental View Maintenance for Deductive Graph Databases Using Generalized Discrimination Networks
Nowadays, graph databases are employed when relationships between entities are in the scope of database queries to avoid performance-critical join operations of relational databases. Graph queries are used to query and modify graphs stored in graph databases. Graph queries employ graph pattern matching that is NP-complete for subgraph isomorphism. Graph database views can be employed that keep ...
متن کاملIncremental View Maintenance for Property Graph eries
Graph processing challenges are common in modern database systems, with the property graph data model gaining widespread adoption [29]. Due to the novelty of the eld, graph databases and frameworks typically provide their own query language, such as Cypher for Neo4j [27], Gremlin for TinkerPop [28] and GraphScript for SAP HANA [24]. These languages often lack a formal background for their data ...

متن کاملAdaptive Stream Clustering Using Incremental Graph Maintenance
Challenges for clustering streaming data are getting continuously more sophisticated. This trend is driven by the the emerging requirements of the application where those algorithms are used and the properties of the stream itself. Some of these properties are the continuous data arrival, the time-critical processing of objects, the evolution of the data streams, the presence of outliers and th...
متن کاملUsing Schema Transformation Pathways for Incremental View Maintenance
In heterogeneous data warehousing environments, autonomous data sources are integrated into a materialized integrated database. The schemas of the data sources and the integrated database may be expressed in different modelling languages. It is possible for either the data or the schemas of the data sources to be updated. Incremental view maintenance is one of the problems being addressed in da...
