Provided are a method, system, and program for generating a program capable of invoking a flow of operations, wherein the program is capable of being initiated from an external call. A definition file defining a flow of operations and mapping information defining input parameters to the flow of operations are received. The received definition file and mapping information are processed to generate program statements within the program that when executed perform: setting input parameters to the flow of operations to values received from an external call to the program; invoking the flow of operations with the input parameters including values from the external call; and receiving output from the flow of operations and extracting at least one value from the received output to return to the external call.

Method, system, and program for generating a program capable of invoking a flow of operations

A method, apparatus and program storage device for mapping data objects, residing in multiple data sources or generated dynamically, into a single or multiple reusable software components, for integrated information access to multiple disparate data sources, residing on or generating the data dynamically on different hardware systems and possibly in different data formats. A user identifies selected data objects from multiple data sources and registers them with an information integration software facility, in order to create at least one virtual data object having at least one attribute from the selected registered data objects, and to wrap access to the at least one virtual data object into a reusable software component, as though it was a single real data object, accessible directly from software applications.

Mapping data from multiple data sources into a single or multiple reusable software components

A method, apparatus and article of manufacture is provided for mapping data objects residing in multiple data sources, or generated dynamically, into a single, reusable software component, for integrated information access to multiple disparate data sources, residing on or generating the data dynamically on different hardware systems and possibly in different data formats. The method has steps for identifying data objects in multiple data sources, employing an information integration software facility for connecting to the data sources containing the data objects, and registering the data objects with the software facility, creating a single virtual data object consolidating multiple attributes from the registered data objects, and establishing a connection to the software facility for referencing the virtual data object as though it was a single real data object. It also has a step for wrapping this virtual data object as a reusable software component accessible directly from applications.

Mapping data from multiple data sources into a single software component

A method, apparatus, and article of manufacture for detecting shared temporal relationships in a relational database. In accordance with the present invention, an invocation of a shares operation that specifies a first event and a second event is received. In response to the invocation, a combination of temporal relationships between the first event and the second event are evaluated to determine whether (1) the second event ends after the first event starts and the first event ends after the second event starts or (2) the first and second events start and end at the same time.

Technique for detecting a shared temporal relationship of valid time data in a relational database management system

A system, method and program extender for enforcing the uniqueness of temporal data in an object/relational database management system is provided. There is a combination of user-defined functions, triggers and specified conditions to determine if attempts to insert new data or update existing data in a data object in which temporal integrity is a consideration are valid. Barriers exist to protect against inserts or updates that would violate the temporal integrity of the existing data. Also included are ways for a user to modify the behavior of the system or method to override triggers for cases in which temporal integrity is not desired.

Technique for enforcing temporal uniqueness in an object/relational database management system environment

A method, apparatus, and article of manufacture for detecting subsuming temporal relationships in a relational database. In accordance with the present invention, an invocation of a within operation that specifies a first event and a second event is received. In response to the invocation, a combination of temporal relationships between the first event and the second event is evaluated to determine (1) whether the second event starts at the same time as the first event or whether the second event starts before the first event and (2) whether the second event ends at the same time as the first event or whether the second event ends after the first event.

Technique for detecting a subsuming temporal relationship of valid time data in a relational database management system

A method, apparatus and article of manufacture is provided for mapping persistent data objects residing in multiple data sources into a single, reusable software component accessible to an object-oriented programming language application performed by the computer, for multi-database access to data that may be physically distributed and stored in disparate DBMSs, each stored in an electronic storage device coupled to the computer. The method has steps for identifying data objects in multiple data sources, employing a multi-database software facility for connecting to the data sources containing the data objects, and registering the data objects with the multi-database software facility, creating a single virtual data object consolidating multiple attributes from the registered data objects, and establishing a connection to the multi-database software facility for referencing the virtual data object as though it was a single real data object. It also has a step for wrapping this virtual data object as a reusable software component accessible directly from object-oriented programming language applications.
