Data Models

Data model is core of the system of managing, analyzing, and sharing data from project DGV4VN (MASH). The data model includes data items and properties that are described by a data dictionary. This model is represented in terms of graphs which capture relationships between data components.

Data model is designed to maintain data and metadata integrity and consistency. It should be able to support ongoing changes in data and technologies. It should be able to support frequent and complex queries from both internal and external partners. It should be able to support indexed documents and data validation for partners to submit data to the system. To meet these requirements, the data model is designed using graph representation, ontology-based concepts, and schema-based entity and relationship validation.
