In general, if your data structure may change later and if scale and availability is a bigger requirement then a non-relational database is a preferable choice.
What database does Wikidata use?
Blazegraph
It uses Blazegraph as its triplestore and graph database.
Is DBpedia a knowledge graph?
DBpedia is a crowd-sourced community effort to extract structured content from the information created in various Wikimedia projects. This structured information resembles an open knowledge graph (OKG) which is available for everyone on the Web.
Is RDF a database?
The RDF triplestore is a type of graph database that stores semantic facts. RDF, which stands for Resource Description Framework, is a model for data publishing and interchange on the Web standardized by W3C. Being a graph database, triplestores store data as a network of objects with materialized links between them.
Is SPARQL similar to SQL?
SPARQL and SQL have very similar UNION and MINUS operators, which respectively add and remove solutions from a solution set. Because the datatypes of an SQL table are assumed to be uniform across all rows, care must be taken to align the datatypes of the SELECT.
What is DBO ontology?
The DBpedia ontology is the heart of DBpedia. Having started as a manually created ontology based on the most commonly used infoboxes within Wikipedia in 2008, it soon evolved into a successful crowd-sourcing effort resulting in a shallow cross-domain ontology.
What are the 3 main types of databases?
hierarchical database systems. network database systems. object-oriented database systems.
Is SQL is a database?
SQL Database Definition
SQL database or relational database is a collection of highly structured tables, wherein each row reflects a data entity, and every column defines a specific information field. Relational databases are built using the structured query language (SQL) to create, store, update, and retrieve data.

What DBMS does Wikipedia use?
Wikipedia is powered by the MediaWiki software, which was originally written to run Wikipedia and is now an open source project. MediaWiki uses PHP running on a MySQL database.
What is the difference between Wikidata and DBpedia?
What is the difference between graph database and knowledge graph?
Graph Database vs Enterprise Knowledge Graph. What distinguishes an Enterprise Knowledge Graph platform from a plain old graph database? The difference is using graph for data storage versus using graph for data management.
Is RDF still used?
Although the RDF/XML format is still in use, other RDF serializations are now preferred by many RDF users, both because they are more human-friendly, and because some RDF graphs are not representable in RDF/XML due to restrictions on the syntax of XML QNames.
How does RDF store its data?
RDFStore implements a generic hashed data storage that allows to serialise RDF models, resources, properties and property values either to disk or in-memory data structures. It does support several different persistent storage models such as SDBM, BerkeleyDB (standard and Sleepycat) and DBMS.
