Abstract: A centralized method for defining and enforcing strong-typing among domains in RDBMS or ORDBMS is provided to allow flexible, easy, and quick domain creation, as well as facilitating easy implementation and change control on domains. When an application requests data from the database, one or more domains are first identified in the SQL query. A determination is then made as to whether operators for each domain pair in the SQL query are authorized. A determination is also made as to whether functions in the SQL authorized. If the operators and functions in the SQL are authorized, the initial SQL request is rewritten to include a casting formula for each domain pair operation. The rewritten SQL request is then executed.

Abstract: A method for storing a user evaluation of distributed content comprising an Evaluation Program (EP) that creates a user session when a user accesses distributed content. The user evaluation is saved with other information such as the time and date of the evaluation, the user's personal information, and the navigation path the user used to access the distributed content page. The EP records the user's navigation of the distributed content in the user session. The EP gives the user the opportunity to rate distributed content. The EP saves the user's evaluation with the user session data and external stimuli data. The EP closes the user session when the user leaves the distributed content. The EP reopens the user session when the user returns to the distributed content.

Abstract: A method for capturing a user evaluation of distributed content comprising an Evaluation Program (EP). The user evaluation is saved with other information such as the time and date of distributed content access, the user's personal information, and the navigation path the user used to access the distributed content page. The EP creates a user session that records the user's navigation of the distributed content. The EP uses incentive programs to entice the user to rate the distributed content page. The EP gives the user the opportunity to rate distributed content if the distributed content page has a content rating window and if the user meets the minimum evaluation criteria for the distributed content page. The EP displays a content rating window allowing the user to rate the distributed content page. The EP saves the user's evaluation with the user session data and closes the user session when the user leaves the distributed content.
