Unified Approach for Structural Coherence in Data Layer of E-Government Services

Multiple view points during design phase about entities that are holding data and independent analysis by different organizations lead to different versions of same entity that are structurally incoherent or inconsistent. Hence centralized publishing of minimal definition of entities play useful role in reducing the duplication of effort involved in e-Government projects. E-Government solutions deal with multiple databases that may store data about different versions of same entity. Present paper is an effort to present language based solution to bring structural coherence in data layer of e-Government solutions. Schema based approach for Entity Definition has been proposed to define structure (vocabularies) for government entities and their metadata. Its adoption by authorities will ensure structural coherence among federal databases and allow the organization to harness the power of reusability and facilitate the rapid development of services based on similar entities.
