- 3. Overview AllegroGraph is a database and application framework for building Semantic Web applications. It includes support for Federation, Social Network Analysis, Geospatial capabilities and Temporal reasoning. Software genre: Graph database. Protocols used: Resource Description Framework. Developer: Franz Incl.
- 4. Introduction Allegrograph is a framework to develop semantic web applications. - Semantic web technology aim to build websites. - Sufficient self describing data. It is a high performance Graph Database. Store data and metadata in triple format. Provides various query APIs to perform query triples. AllegroGraph actually stores quints.
- 5. Figure 1.Logical Structure of an AllegroGraph triple store - A triple in AllegroGraph contains 5 slots, the first three being subject (s), predicate (p), and object (o). - The remaining two are a named-graph slot (g) and a unique id assigned by Allegro Graph. - The id slot is used for internal administrative purposes, but can also be referred to by other triples directly.
- 6. Features ACID transactions and Recoverability Read/Write concurrency -100% read concurrency at all times. Dynamic and automatic indexing - With column based compression. Resource management - Use all disks, all memory all processors(one box). - Automatic or user configurable.
- 7. Advantages Scalable and persistent quad store. Federated Compliant with standards - RDF, RDFS, OWL, SPARQL, Named Graphs, ISO Prolog, OWL-lite reasoning. “Minutes to Milliseconds” performance. Drastically-accelerated development cycles.
- 8. Disadvantages Does not support for portability. Sharding ( lots of people working on this) - Scales UP reasonably well Requires rewiring your brain. Very easy to describe data inconsistency. Can be conceptually difficult to understand at very first look.
- 9. Applications Route finding (going from point A to point B) Logistics Authorization and Access Control Network Impact Analysis Network and IT Operations Management Social Networking
- 10. Recent Projects Allegrograph is used in many commercial, Open Source, Defense projects as a data store. Some of the significant ones are:- - DBpedia Germany - Genome Web - Tweet logic
- 11. Comparison Of Graph Databases
- 12. Conclusion Here at the end we conclude that we have studied about the Allegrograph database. AllegroGraph uses disk-based storage, enabling it to scale to billions of triples while maintaining high performance through indices. Advantages, disadvantages of the Allegrograph database and its application comparison of graph database. Comparison shows that Nested graphs is not supported by most of the graph database.
