In recent years, \"Document store\" NoSQL systems have exploded in popularity, largely driven by the adoption of the JSON data model in Web and mobile applications. The advantages of these NoSQL document store systems (like MongoDB and CouchDB) are tempered by a lack of traditional RDBMS features, notably a sophisticated declarative query language, rich native query processing constructs (e.g. joins), and transaction management providing ACID safety guarantees. In this paper, the authors hope to spark a discussion in the database community about how JSON data can be supported on top of a relational infrastructure, and how the best features of JSON document stores and relational databases can be combined.
