We have examined the characteristics of RDF data and how it is stored in the DB2 database. You walked through the process of creating an optimized store and reviewed its benefits by comparing it to a default store.
You then learned how to create an RDF store with graph-level access control. The tutorial explained how to implement graph-level access control by using the column and row access-control feature and by using the Java API.
In Part 3, we cover the basics of how
DB2 software converts SPARQL to SQL. We will then delve into more
SPARQL-specific features, such as the
forms and creation of a union of named graphs.
