Data Modelers Still Have Jobs: Adjusting for the NoSQL Environment

Editor's Notes

• #6: Point of having a merged cell for physical: it’s all coming together – it’s increasingly difficult to distinguish the underlying physical model services…Here again, hypertext is not 1:1 with HTML – it’s beyond-the-basics hypertext as manifested, e.g., in Web publishing and collaboration-oriented systems/serversXQuery is not mainstream today, but it is exceptionally powerful and was co-developed in conjunction with XPath 2.0

• #18: Point of this slide: reinforce ability to discern major similarities/differences between two tools/services focused on similar domain, by comparing/contrasting model diagrams Non-technical people can easily learn how to read/use this type of model – not the case with most logical and physical model diagramming techniquesEvernote conceptual model fragment example from http://www.quepublishing.com/articles/article.aspx?p=1684320 Incomplete – a full conceptual model includes accompanying documentation, e.g., with entity definitions and examplesMicrosoft OneNote 2010 conceptual model fragment example from http://www.quepublishing.com/articles/article.aspx?p=1684320 Reason for including it: it provides an example, comparing it to the Evernote conceptual model fragment, of how easy it is to understand domains, when using conceptual models – e.g., the fact that OneNote has a more elaborate info item containment structure, and supports tags at the item/paragraph level, while Evernote tagging is at the note/page level. That’s not meant to be a judgment call; the extent to which Evernote or OneNote is more useful is a function of your info item/note-taking needs.
