How does the VES approach assist with development and maintenance of data exchanges?
The VES approach simplifies development and maintenance of data exchanges using inheritance features and plug-in support. It eliminates software licensing costs, server costs and much of the administration costs for partners, while providing a simplified development model and greater economies of scale. State, Tribal or territorial administrators retain complete control of all aspects of their VES, their data flows and access to their staging tables or databases. VES is currently in production with large and small states, Tribes, and air districts. Some states are using VES for new flows listed in Table 1 and keeping their physical nodes for existing flows.
