Data sharing in the public sector: authorized, secure and in real time

To overcome these data integration challenges, agencies are turning to data virtualization. Rather than facilitating the transfer of data from one agency to another, or the integration of data from numerous different files collected from different agencies, data virtualization provides secure, authorized views into different datasets, leaving the data in its original location. This means that there is no need for the receiving agency to physically store any more information than is strictly necessary.Data virtualization acts as a layer between agencies, facilitating real-time, authorized data access. As such, the data virtualization layer itself holds no data; instead, it contains the meta-data required for accessing the available data, including the appropriate controls for which individual or group is authorized to view which dataset.
