A method, article of manufacture, and apparatus for processing continuous value data is disclosed. Data values stored in a database reflect a measurement of the value obtained for a specific point in time. In order to correlate the evaluation of two or more conditions, when measurements for each condition recorded at the same points in time are unavailable, embodiments of the invention provide a method for generating approximations of the unavailable values for comparison with others. Thereafter, a comparison between values for the points in time may be used to correlate the two conditions during query processing.

A method, system and article of manufacture for managing access to query results and, more particularly, for managing access by multiple users to persistently stored query results, whereby at least some of the users may have different access rights. One embodiment provides a method of managing access to a query result obtained upon execution of a query against one or more databases. The method comprises creating security information configured for restricting access to the query result. The security information is associated with the query result. Access to some or all of the query result is granted to a requesting entity on the basis of the security information and an attribute of the requesting entity.

A method, system and article of manufacture for intelligence building in expert systems and, more particularly, for evaluating treatment decisions overriding recommended treatments that are generated by expert systems. One embodiment provides a method of evaluating treatment decisions, comprising receiving a specification of a decided treatment for a patient having a given disease. The decided treatment differs from a recommended treatment identified by an expert system in response to analysis of symptomatic data corresponding to the patient. The patient is monitored subsequent to being treated according to the decided treatment. The decided treatment is evaluated on the basis of data captured by the monitoring. On the basis of the evaluation, feedback with respect to the decided treatment and the recommended treatment is generated.

An apparatus and method modify a saved query based on a change in a query value meaning that changes over time. In preferred embodiments a graphical query interface displays an option to adjust query values of a saved database query. A query adjustment mechanism then adjusts the value of the query to compensate for the change in the meaning of the query value since the query was created such that the adjusted query will have the same basic meaning as when the query was originally created. Preferred Embodiments allow the user to specify to adjust the query to the current date or to a specified date in the past.

A method and apparatus for representing a continuum of data as a rolling column within a relational model is disclosed. Data from a continuous data source may be used to populate a rolling column. Metadata defining the rolling column specifies the correct portion of data from the continuum of data that should be used to populate the rolling column. Whenever data from the rolling column is included in a data access request, such as a database query, a database management system may be configured to update the rolling column, according to the metadata.

A method, system and article of manufacture for processing rule sets and, more particularly, for processing abstract rule sets. One embodiment provides a computer-implemented method of managing execution of an analysis routine configured to process one or more inputs. The analysis routine is defined by at least one abstract rule set having one or more abstract rules each having a conditional statement and a consequential statement. The method comprises determining, from the retrieved analysis routine, a predefined validating condition that needs to be satisfied by at least one of the inputs, and validating a particular data value defining the at least one of the inputs on the basis of the predefined validating condition. If the particular data value is not validated, a predefined action configured to avoid execution of the analysis routine on invalid inputs is performed.

A method, apparatus, and article of manufacture are provided to optimize the time and effort required to locate all data on a given entity that may span multiple data nodes in a distributed environment. For example, embodiments of the invention may be used to locate nodes within the distributed environment that store electronic healthcare records. A poll request from a first node to a second node may include electronic records existence data indicating data nodes known to have, or not have, records related to a given individual. This information is used to minimize the number of nodes that need to be polled to arrive at the complete aggregation of patient records that exist within a given set of nodes.

Embodiments of the invention provide methods, systems and articles of manufacture for constructing a database abstraction model over an underlying physical database. Typically, queries of the database abstraction model are directed to queries of a model entity defined for the database abstraction model. To compose an abstract query, users select conditions evaluated using data associated with instances of the model entity. Using the database abstraction model, users may compose an abstract query according to logical or intuitive relationships among data elements stored in the underlying database. One addition to the database abstraction model is the ability to apply query criteria against related instances of a model entity. Because model entities may share a predefined relationship, embodiments of the invention allow for users to specify query criteria applied against related instances. Related instances may be identified by invoking a path function provided by the database abstraction model. A path function may be configured to return instances of the model entity that are related to an instance input to the path function.

Embodiments of the invention provide techniques for constructing a database abstraction model over an underlying physical database. Once constructed, users may interact with the database abstraction model, rather than the underlying physical database representation, to query the database and view query results. In one embodiment, information is retrieved from the underlying physical database that is related to a model entity. Generally, a model entity identifies the logical focus, or the central entity, being queried by user interacting with a query application. An abstract record identifies what data about each model entity is available to query using the database abstraction model. In addition, once presented with data for an instance of a first model entity, embodiments of the invention provide for a user to switch the display presented to an instance of a second model entity. A conversion function may be used to map between model entities.
摘要:
A method, system and article of manufacture for managing access to a data abstraction model abstractly describing physical data and, more particularly, for creating a logical security model for a data abstraction model abstractly describing data in a database. One embodiment provides a computer-implemented method for creating a logical security model based on a physical security model defining user access rights to physical data. The method comprises, for each of the user access rights defined by the physical security model, creating a logical access right definition for a logical model. The logical model comprises a plurality of logical field definitions each comprising a field name and access information for accessing a field of the physical data. The logical access right definitions are applied to the logical model so that the logical model reflects the user access rights to the physical data.
