-    COMPARISON    

Comparison: UD6/CMtool Driver and Compuware's Uniface 8 SCCI Bridge

The Source Code Control Interface that is delivered with UNIFACE V8 relies on an import/export system that is not suitable for the implementation of Source Code Management / Configuration Management in most organisations.

Reports from SCCI Users:
1
We have not found the new [Uniface 8 SCCI] interface very satisfactory. There just isn't very much flexibility. It performs imports and exports [like VC-Link] and there is not the flexibility that's required in a really good solution.
2
The problem I had with SCCI bridge of UNIFACE was that there was no security. The UD6 driver solves that in a very nice and simple way. Configuration was easy enough.

Note (1) : Optionally, depending on configuration settings.

Note (2) : Optionally, provided that the SCM/CM tool of your choice supports this feature.

Note (3): Uniface must be configured to store exports as XML files.

Note (4) : The format that Uniface 8 uses to export the Form layout (paint tableau) makes it difficult to identify the changes to the location of objects "painted" on a form.

Note (5.) : UNIFACE 8 SCCI always uses the options: 'work case sensitive', 'ignore white space', 'normal diff'. Merge is not possible..

Note (6.) : Compuware's MyUniface.com sitelists only brief comments for PVCS VM and Continuus CM technical setup.

Note (7.) : Compuware's MyUniface.com sitelists says: "Button Retrieve Opens form 'Select Sources' which does a call to the SCCI to get all known files from the current project (this can take a while, depending on your SCCS), with their state. ".

Note (8.) : Non-US ASCII characters are stored as 4 digit numbers in the Uniface 8 XML files. UD6 can store these as native characters (either Unicode or non-Unicode).

Note: This comparison is based on Uniface 8.2.03 and UD6/CMtool Driver 1.03. As far as March Hare are aware, these details are true and correct for the latest versions of these products.
