Managing documents alongside semantic information

Managing documents, search, semantics, and analytics

Hybrid NoSQL databases fall into two categories:

• Those that use a non-relational data type and triples to store relationships and metadata about those records
• Those that integrate search with document structures (whether they are key-value stores or document databases)

Using a triple store approach to provide schema agnosticism in the relationships mirrors the way that NoSQL databases provide schema agnosticism in their own records’ data models. A triple store approach to relationships between records goes some way towards providing cross record information links, avoiding some of the need for producing denormalizations.

OrientDB, ArangoDB, and MarkLogic Server all take the document-oriented approach, using triples to store relationship information either within, or independently of, the document records they describe.

There is a level of depth required in multiple NoSQL areas (such as document, triples, and search) that is required to be a true hybrid NoSQL database.

In this chapter, I describe the most common data management use cases that hybrid NoSQL databases are used for.
