SUMMARY
This chapter introduced the essential create, read, update, and delete operations in the context of
NoSQL databases. The chapter explored the essential operations in light of three kinds of NoSQL
stores, namely, document stores, column-oriented databases, and key/value hash maps. MongoDB
represents the document stores, HBase represents the column stores, and Redis represents the
key/value hash maps.
During the discussion it became clear that for all the data stores, data creation or insertion is more
important than updates. In some cases, updates are limited. Toward the end of the chapter, the topic
of updates, transactional integrity, and consistency were also explained.
