For Dummies series does amazing job in explaining everything in plain language without dramatic loss of depth or excessive oversimplification. They are very good to get you started with the subject.\nMy first tech book long time ago was Networking for Dummies (in Russian), and it was both fun to read and informative, all my tech knowledge prior that was based upon trial and error approach 🙂 Probably should re-read latest edition of Networking for Dummies for the sake of knowledge refresh and very good memories of 1st experience of for Dummies series :)\nAs for Oracle 12c book: I preordered digital edition from Amazon, and overall it nicely covers quite a wide array of things you need to know to approach Oracle 12c RDBMS. It seems that Oracle 12c system far more sophisticated/feature-rich platform than MS SQL Server – though probably I just don’t know MS SQL Server well enough (need to go through respective for Dummies book?). To some extent there is more to learn here platform wise as it can run both on top of Linux and Windows – so there are far more options and ramifications for deployment and configuring it.\nThe only bad thing about this edition is amount of very obvious typos/editing errors – didn’t expect that from respective brand/publisher. When language errors obvious even for non-native speaker it’s not what you want to allow as respective publisher I guess.
