History

To inspect the history of a data set click on the button. A window will open showing all former states of the data in tables with the current data set at the top.

If you have sufficient access rights for the database (role administrator), the buttons Restore deleted and Restore data as in selected line are available (see image below). If you want to restore an old version of a data set, choose the corresponding line in the table and click on the Restore data as in selected line button.

If you want to restore a whole data set including the dependent data, click on the Restore deleted button. This function is as well available from the menu Data → Restore from log …. In the upcoming dialogs choose the basic table to start for the search. In the upcoming dialogs enter the date where the query should start and the number of lines from the log table that should be displayed. Finally select the datarow(s) of the root table that should be restored. After that the program will try to recover the data with all depending information.

Depending on selected edit mode (“Descriptions”, “Descriptors” or “Projects”) the marked tables in the overview below may be selected as basic tables for restorage. With “->” dependent tables are marked that will be restored automatically, if the parent has been successfully restored.

Edit mode “Descriptions”:

-> CategoricalSummaryData				-> QuantitativeSamplingData
-> QuantitativeSummaryData				-> TextSamplingData
-> TextDescriptorData				-> MolecularSequenceSamplingData
-> MolecularSequenceData
	->	Resource *	->	ResourceVariant

Edit mode “Descriptors”:


Translation

Edit mode “Projects”:


Translation

* Remark: If you restore an object that assigns resources, be aware that during delete processing in many cases the link from the resource to the deleted object was set to null before deleting the resource itself. In those cases after restoring the target object you have take a look in the history to restore the resource link using the button Restore data as in selected line.

After successful restorage a message will give you an overview of the performed actions.
