Today it is time to say "Thank you" to the Oracle Technology Network (OTN) for keeping up one of the worlds greatest developer community.
One cool thing within the Oracle Development ecosystem I really like is the availability of an technology agnostic Design Guide, including Style, Patterns, Cookbook, etc. called ALTA UI. Besides containing best practices for designing great User Experiences it allows to introduce new technologies under the covers. The user does not notice if something is build in ADF, JET, MAF or technology X which implements the Alta UI Patterns.
