DETAILED USER & TECHNICAL REQUIREMENTS FOR CDPS
AND USE-CASE MODELS
Ref: PHASE V
Number
Description
new business item, the modification of an existing item or the deletion of
an existing item.
• Applying a work package. Applying a work package means that all
business data modifications are made public. Everybody can see the
content from this moment on. The timestamp and the identity used when
the work package is applied is persistently stored. An applied work
package cannot be altered or removed.
• Cancelling a work package. This operation actually removes all business
modifications done in the context of the package together with the package
itself. Cancel is a complementary operation to apply. One can execute a
cancel or an apply operation and an applied package cannot be cancelled
and vice versa.

5.2.11 User Interface
CDPS can provide two different kinds of interactive interface. The first is a web interface based on
HyperText Markup Language (HTML) i.e a thin client, and Server side processing of HTTP
requests. The second is a thick client with rich graphical user interface, and a significant client –side
data processing.
If a web interface is deployed, then the latest version is always used. However, in some cases, a web
interface may be relatively poor and its interactivity may be insufficient. Moreover, this kind of
interface often requires a lot of bandwidth since the client, typically a web browser, must interacts
with the server for each user operation. If CDPS uses Web interface, then CDPS must make
extensive use of AJAX.
Using a thick client may have the following benefits
• A more interactive user interface
• Lower bandwidth requirements. The application does not go to the server for each user
interaction;
• In some cases, the application can be used off-line.
The trade-off is that the application and all its future releases must be deployed to all client
workstations.
