Together with my colleague Mojca Gros of Qubix, we have delivered webinar session with the title Oracle Analytics: Tips & Trick at this year's SIOUG annual conference MakeITWeek2020. In a record time, Oracle Analytics has undergone a transformation from a “old-fashioned” business intelligence tool to a modern, mature, and comprehensive analytics platform that runs in the cloud or, if you want, on a user’s server. New functionalities are being introduced on a very frequent basis, and these are very difficult to keep track of. Be it in the field of data visualisation, data preparation for analysis, machine learning or infrastructure changes.

When snapshot is created, one would usually download the snapshot in the form of the .BAR file. After the snapshot password is provided, download can begin. In my old habit I then simply renamed .BAR file into .ZIP file which is then extracted. In the extracted folder, .RPD file is located in the \datamodel\rpd subfolder (in the screen below, I copied default.rpd file to Desktop folder).  And if you try to open the .RPD file this way from Model Administration Tool (...
