摘要:
A method, system and article of manufacture for relationship building based on text-based markup languages and, more particularly, for representing relationships between data elements defined according to a first physical representation of data in a logical representation. The logical representation abstractly describes a second physical representation of the data, which is generated from the first physical representation of the data. On the basis of the relationships between the data elements, logical relationships each defining a path between data structures of the second physical representation are determined and associated with the logical representation.

Embodiments of the invention provide methods, apparatus, and articles of manufacture for managing different versions of a data model standard in both abstract and physical database environments. In one embodiment, new versions of the data model standard are analyzed to identify changes introduced by the new version. The database schema, organized according to the initial version of the standard, is then modified to reflect these changes. Logical representations of the data are provided that expose data organized according to both the initial version of the standard and according to the subsequent version of the standard.

A graphical query interface provides visual feedback to a user during the construction of a query. In a first embodiment, the visual feedback helps the user determine the quality of the query as the query is being built. The relationship of columns in the database is graphically displayed to a user. When the user selects a column in the database, a filtered display mechanism displays only those columns or records that satisfy the portion of the query already constructed. In a second embodiment, the visual feedback eliminates some possible selections in the query tree due to previously-made selections that eliminate the eliminated selections as possibilities. In the second embodiment, the visual feedback mechanism may function according to data values in columns, and may also function according to known relationships between columns themselves.

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.
摘要:
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.
摘要:
The present invention is generally directed to a system, method and article of manufacture for accessing data represented abstractly through an abstraction model. In one embodiment, a data repository abstraction layer provides a logical view of an underlying data repository that is independent of the particular manner of data representation. For each successive query, the data repository abstraction layer is replaced or redefined to provide a restricted logical view of the underlying data repository.

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, 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.
摘要:
Embodiments of the present invention provide methods for constructing a database abstraction model that includes logical fields that map to a logical table. The logical table is constructed using data extracted from multiple, differently formatted physical tables. The logical table allows logically related data stored in multiple databases to appear as data from a single table. Relationships between data stored in multiple, differently formatted databases are maintained and logical fields that include multiple access methods that map to the multiple databases are replaced with a single access method that maps to the logical table. Data relationships that are defined for the database abstraction model are modified to reflect the logical table.
