As roads and bridges are designed, intelligence about these objects is added to the SDBMS either through entry of attribute data or integration with external databases.
Like the relational model, an SDBMS manages data and provides it to multiple, concurrent users so that objects/features and their attributes, whether used for CADD, AM/FM, or GIS applications, meet the individual needs of each user, Objects and their topological relationships are managed independently of the applications software, and users can retrieve objects/features from the model in accordance with their specific analysis and display needs without concern for how the model organizes and stores data.
The parts or materials that may be needed to make the repairs can also be determined - all using the same SDBMS.
