This report describes the data modeling for the digital library of reporting templates. It presents an approach to data modeling by first creating the use cases and then identifying the library system components and finally putting together database tables.

Based on RadLexTM and other standard terminologies, a digital library of standardized radiology reporting templates has been developed by the Radiological Society of North America (RSNA). The library is a database-driven web portal with a searchable collection of standardized reporting templates stored in textual format and/or XML-encoded document.

The digital library of radiology reporting templates has been developed with a relational database, containing a combination of structured reporting data for publishing on the Web. Initial contents have been acquired from radiologists via templates, converted to an XML document reflecting the underlying database schema, and then loaded into the database. To describe users' interactions with the digital library, we used Unified Modeling Language (UML) data modeling techniques to create use-cases including add/update/submit template profile, process template browsing and search, collect search terms, and generate reports, which explain "who" will do "what" with the library system by detailing a sequence of activities. We created a use case diagram to present a graphical overview of the functionality provided by the library system. We further employed UML sequence diagram to specify these use cases and simplify overviews of the system's behavior.  

We have produced a data model based on UML. The data models are being used in the first stage of the template library system design to describe information needs and the type of information that is to be stored and processed in the database. The use cases have been used to capture the system's behavioral requirements by detailing scenario-driven threads through the functional requirements and identify the subsystems and components.
