GP & CAF & UWL

Question

Hello All
Please tell me the difference between GP(Guided Procedures), CAF(Composite Application Framework), & UWL(Universal Worklist)..
I already have links/threads related to this..
But what basically i want to know is what exactly is the diiference is  b/w 3 of them....m confused..
Dont give links..just explain me...
Regards....
Thank You!!!

Hi,
Both GP and UWL are component of business task management
here are the functions of UWL
Single point of access for managing your work
•Can be personalized to suit each user’s working style
•Process-specific views can be customized for expert users
here are the functions of GP
Designed to implement process flows with greater ease and speed across
multiple applications
• Integrates back end system transactions and interactive forms
• Includes process templates that can be easily re-used or copied and easily
changed
When we need to use GP?
suppose if u r the admin of the room and u want to implement certain services to the rooms which access Backend system data like BI iviews in collaboration rooms, then u will follow some guided procedure i.e u go room part template and add this Bi iview to the room.
Mostly all GP process are carried out at business user level.
one more example is room admin can make uwl as part of the room where users can carry out room specific task.
when we need to use UWL?
as i said earlier uwl provides
Single point of access for managing your work ( like u can get work task from collaboration,backend,room specific task etc)
CAF is a technology put together by SAP in order to provide application developers tools to build next-generation solutions in a way that is model-driven, flexible and service-oriented. CAF is primarily two pieces of technology that addresses two key layers of an application architecture: the process layer and the service layer.
At the Process layer, the tool is known as Guided Procedures (GP). GP is a tool for functional people or business process experts (BPX) to compose business processes using a collection of user interfaces (UIs like WebDynpro, BSP, html, even R/3 transactions,u2026) or services (BAPIs, Web services, Java classesu2026) and define the process flow and data flow in an environment to is code-free. GP has a design time and a runtime. You design and run. And if you want to change the process you edit and run again. No coding at this level.
At the Service layer, the tool is known as CAF Core. It's a tool for technical people or enterprise architects to define the services that the UI or process layers would consume. In CAF Core you can define Entity Service to represent the data model of your application. You can also reference the entity to a remote persistence system as opposed to being local. For example my composite needs to manipulate customer info but my customer information already is persisted in R/3, then you can define the customer entity in CAF Core and reference the R/3 customer info via a BAPI or Web service. CRUD (Create/Read/Update/Delete) methods are automatically generated for each entity and you can interact with them either via UI Patterns or Web service. No coding is required so far.
If coding is required it's because of there's a need for additional logic and you can represent that into an Application Service that will encapsulate the entity service with the additional code and will be accessible to the UI or process layer via UI Patterns, Web services or CAF Application Services. At this point coding is required.
