National e-Service Bus Mapping to the TOGAF Standard

Figure 5 describes the core pillars of the BNDA and their mapping to the TOGAF Standard.

Core Pillars Definition

Business

Common approach towards the realization and visualization of government activities.

Data

Data is owned by individual government bodies and should be reusable.

Application

Introduces shared services and systems.

Interoperability

Enables exchange of data and services across government organizations. The National e-Service Bus (based on SOA) is the core of integration in the BNDA.

Mobility

Mobile and Internet technology has created new platforms for government agencies/organizations as well as consumers.

Technology

Multiple ICT infrastructures and networks.

Security

Security is the largest common concern area when dealing with government enterprises and their data being exchanged and being used internally, and externally.

In line with other globally recognized frameworks based on the TOGAF Standard, the structure of a national Enterprise Architecture consists of a number of reference architectures, each dealing with a specific domain of Enterprise Architecture. The National e-Service Bus is a core middleware integration component of Technology Architecture.

The National Enterprise Architecture Framework is a close representation of the entities relevant to a domain of the Enterprise Architecture, the inter-relationships among those entities, and the standards to be followed by each of the entities. The overall structure of the national Enterprise Architecture is organized into two sections: Whole-of-Government and Ministry. The framework has mainly four dimensions and includes two cross-cutting dimensions: governance and security. Those dimensions are overarching and apply to both Whole-of-Government and Ministry. The remaining four dimensions, each of which contain a reference architecture are: Business, Application, Data, and Technology. These dimensions apply to both Whole-of-Government and Ministry. However, the artifacts falling under each of those dimensions varies. Figure 6 provides a structural view of the National Enterprise Architecture Framework, capturing the dimensions and artifacts.
