Government Systems Suitability of RM-ODP for e-Government Example: The eMayor Case Study Conclusions
The e-Government Context
Development of e-government servicesWeb site hosting, limited online
transactionsSecure transactions, interactive service
delivery, cross-border interactions Efficient and secure electronic
exchange and processing of data Geographical dispersion leads to
distributed system architectures
ODP Systems Design Methodologies
Design standardsOMG/CORBAOSF/DCEISO/RM-ODP
Overview of the RM-ODP Standard
Supports distribution, interworking and portability Defines basic concepts of distributed processing Identifies the characteristics that qualify a system
as an ODP system Introduces five viewpoints in order to specify an
ODP system Provides a viewpoint language to describe each
viewpoint Provides distribution transparencies between
system applications
RM-ODP Viewpoint Specifications
Enterprise viewpoint – Policies, purpose of operation and scope of the system
Information viewpoint – Information entities communicated, stored and processed in the system
Computational viewpoint – How distribution of processing is achieved
Engineering viewpoint – Ways of communication between objects and resources needed for this communication
Technology viewpoint – Selected technology of a system
Architectural Requirements of E-Government Systems Interoperability Scalability Security and trust User-Friendliness and accessibility Cost considerations Transparent automated processing Cross-border characteristics Limited training Compatibility with existing infrastructures Mobility aspects
