Uniqueness Detection¶

Ignore this section if you are using Git. It is only relevant for Microsoft TFS or Subversion.

File systems and version control systems allow the coexistence of files with the same name as long as they are located in different folders. Virtual DataPort is stricter regarding how elements can be named in the context of a database:

• Different folders can have the same name as long as their parent folders are different.

• The names of views, data sources of the same type, web services, etc. cannot be duplicated in the same database in any case (e.g. it is forbidden to create a view named My_View in the folder Folder_1 and another view My_View in Folder_2).

This difference between file systems and Virtual DataPort makes necessary to check if the elements included in a check-in exist in other locations of the remote repository in order to avoid having duplicate Virtual DataPort elements in the repository.

Virtual DataPort also has to check if the elements that are going to be affected by a check-out that are either new (from a local point of view) or locally modified, do exist in other locations of the remote repository. It has to do this in order to avoid unexpected behaviors (e.g. experiencing unexpected movements of elements between folders).

The uniqueness detection feature detects these scenarios and lets the user choose what to do:

• Cancel the check-in / check-out operation.

• In check-ins, move the conflicting elements to the same locations as in the local database, and override them with the current changes.

• In check-outs, move the conflicting elements to the same locations as in the remote repository, and override them with the remote changes.

By enabling the uniqueness detection, renaming folders or moving elements between folders, no longer leads to unexpected behaviors (e.g. unexpected movements of elements between folders after a check-out). As explained above, uniqueness detection gives users control on how to deal with this kind of scenarios.
