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.

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 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.
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.

Method, computer readable medium and computer system are provided for coordinating configuration changes among components in a multi-component environment. In one embodiment, a method for changing a configuration of a component in a multi-component environment is provided, the method comprising: receiving a configuration change request for the component; accessing a set of mediation rules which define component relationships in the multi-component environment; based on the received configuration change request and the mediation rules, determining whether one or more corresponding configuration changes are warranted in one or more other components in the multi-component environment; and if the one or more corresponding configuration changes are warranted, sending one or more configuration change notifications to the one or more other components; receiving one or more responses from the one or more other components regarding the one or more configuration change notifications; and sending a configuration change response to the component based on the one or more responses received from the one or more other components.
摘要:
A method, system and article of manufacture for query building and, more particularly, for building query conditions for queries against data in a database. One embodiment comprises receiving user input for constructing a first query condition of a query. Then, user-selectable elements to display for constructing a second query condition of the query are identified. Which user-selectable elements are identified is dependent on the first query condition. The identified user-selectable elements for constructing the second query condition are displayed. Then, user selection of one or more of the displayed user-selectable elements for constructing the second query condition is received. The first and second query conditions define selection criteria for selection of a specific set of the data from the database. The selection criteria are programmatically modified in response to construction of the second query condition on the basis of one or more predefined modification rules, whereby the specific set of the data is altered.

Methods, systems, and articles of manufacture for enhancing abstract queries by utilizing conditional modifiers with logical fields are provided. Conditional modifiers allow for the referencing of multiple physical fields via a single logical field. Further, conditional modifiers facilitate the ability to specify, on an instance by instance basis, which physical field or combination of physical fields a particular logical field should reference.
摘要:
A method, system and article of manufacture for linking logical fields abstractly describing data in a database and, more particularly, for creating an abstract query using linked logical fields. One embodiment provides a method of linking logical fields abstractly describing data in a database. The method includes creating link information for a first logical field from the plurality of logical fields. The link information identifies at least one second logical field from the plurality of logical fields and an associated link type operation. The first and second logical fields are linked using the link information.
