Recall the training centre database of cwck one.

You should research the methodology and technology of document stores and key$-$value stores

by considering a re$-$design of the existing training centre database so that it may operate using

MongoDB & Berkeley DB respectively. As a minimum, your report should compare and contrast

the following aspects $..$

$$ Data Models $/$ Type of Schema.

$$ Query Mechanisms $($e$.$g$.$ Language Support & Connectivity$).$

$$ Management of NoSQL $($e$.$g$.$ Security, Indexing, Concurrency, BackUp & Recovery$).$

$$ Tools for Design & Dev. $($e$.$g$.$ IDEs$).$

Tips $..$ Despite some similarities in core technology, treat the MongoDB & Berkeley DB

platforms in isolation as we are realistically looking at developing using JSON $($JavaScript

Object Notation$)$ for MongoDB & Java $/$ DPL $($Direct Persistence Layer$)$ for Berkeley DB$.$

You should include in your report, snippets of code $($e$.$g$.$ JSON & Java $/$ DPL$)$ that illustrate key

aspects of the training centre database$$s re$-$design, including data models, along with some

queries analogous of cwck one
