+\chapter{Conclusion}
+
+With detailed assessments of several \gls{nosql} database implementations, this
+book aimed to answer the research question \textit{"What are the
+characteristics of today's popular (Open Source) \gls{nosql} databases in
+relation to the CAP theorem?"}. For this, a detailed introduction to
+wide-column-store, several key-value databases, document stores and graph
+databases was given.
+
+It is now clear that for no database implementation one can absolutely state
+that the CAP theorem can be applied. While always some parts of the theorem
+apply to the different implementations, as stated by the CAP literature itself,
+not all aspects can be realized. Though one interesting result is that all
+database implementations aim to be partition tolerant. It was furthermore shown
+that RethinkDB as well as Couchbase are \textit{available}, whereas the rest
+strives towards consistency.
+
+The work of this book is limited by the fact that the research in most fields
+is not up-to-date and literature is in some cases already deprecated. In
+addition to that, only free versions of the specific database implementations
+could be considered, which limits the final statement and answer of the
+research question.
+
+Further work could include a new and more recent benchmark, including current
+problem sets. A unified benchmark with which all database implementations could
+be compared would be of immense value to the field of \gls{nosql} databases.
