Connected Government: An Exploration of the UAE’s Identity Management Integration Strategy: Enterprise Integration

One of the key factors to establish successful identity management is the integration between the different government entities and the entity responsible for managing identities (Bertino and Takahashi, 2010; Chappell, 2004; Williamson et al., 2009; Windley, 2005). For many years, integration has been handled at a system level where the primary focus is to identify what data is needed and how to send it to another system, creating a point-to-point integration pattern. As the number of systems grew, adding more point-to-point integration interfaces led to complex implementations and maintenance of such interfaces, presenting government entities with additional costs, limited flexibility in addressing new requirements, and other risks (Gottschalk and Solli-Saether, 2009; Pollock and Hodgson, 2004).
The challenges mentioned earlier led to the introduction of hub-based and bus-based integration patterns (Li et al., 2009; Watson and Ariyachandra, 2005). See also Figure 1. In hub-based integration, government entities can connect to a central or federated hub to send and receive data between them securely through re-usable messaging and integration interfaces providing performance improvements and scalability.

Bus-based integration introduced the concept of decentralizing messaging between different applications by sending and receiving data in a similar fashion to radio technology, where government entities can connect and send information that can be received by one or many government entities without the need to physically connect to the government entity infrastructure. This provides the flexibility of sending a data set to multiple government entities using a single message.
The aforementioned patterns facilitated the integration between government entities whose focus was to send and receive specific data sets. With time, there has been a shift in emphasis from systems and data integration to overall enterprise integration with an increased focus on inter-enterprise operations, processes, and services, as depicted in Figure 2 (see also Ross et al., 2006).
