Modern businesses rely heavily on enterprise software applications for automating
their business processes. The dependency on these applications drives business owners
to request even more features from the software suppliers. It places a heavy pressure
on suppliers to provide the best possible software quality, without increasing the cost.
The orientation towards generic enterprise applications (ERP, CRM, etc.) is also being
challenged by the variation of demands amongst businesses and users.
Among various components of an enterprise system, the user interface (UI) layer is considered
highly important since it interfaces users to the software system. Employees, with different
roles in the enterprise, could require a variable user interface feature-set and layout for
the same business activity. Some software companies chose to build multiple UIs for the same
functionality due to variable user needs. Yet, in certain situations, the scope of variability
is unknown at design time or it is costly to develop multiple UI versions manually.
Cedar is a platform targeting the development of adaptive user interfaces for enterprise applications,
using a model based approach. Cedar’s primary aim is user interface simplification, which comprises
role-based feature-set minimization and layout optimization. Enterprise software applications include
many scenarios, where users with different roles require variable versions of the same user interface.
Catering to this variability, by providing multiple user interface versions, would enhance usability.
The Cedar Architecture serves as a reference for developing adaptive enterprise
application user interfaces based on interpreted runtime models. We developed a generic
service-oriented implementation of the Cedar Architecture components, which can be consumed
through APIs from different technologies, for devising adaptive model-driven user interfaces.
is an Integrated Development Environment (IDE) for supporting the
development of adaptive model-driven enterprise applications by following the Cedar Architecture.
Cedar Studio supports visual design tools for: Goal Models, Task Models, Domain Models,
Abstract UI (AUI) Models, Concrete UI (CUI) Models, and Adaptive Behavior Workflows.
Cedar Studio also supports a combination of visual design and code editing tools for:
Task Role Assignments, RBUIS Rules, Model Constraints, and Dynamic Scripts.
Furthremore, this tool supports automatic generation and synchronization between the
various levels of abstraction (Task Model, AUI, and CUI) with the possibility to make
manual changes at any of these levels.
The Role-Based User Interface Simplification (RBUIS) mechanism is based on the
Cedar Architecture and includes both feature-set minimization and layout optimization
supported by Cedar Studio.
