摘要:
The present invention relates to an XML application framework (XAF). XAF applications are data driven such that all operations with the computer system are data focused. In addition, the components used in the XAF application are instantiated and connected according to how the data is displayed and what type of data is used. Applications within XAF comprise a user interface (UI) connector, an action module, and a data connector. UI connectors receive UI events and connect the UI event to an action module. The action module generates a standard format action from the UI event and sends it to the data connector. The data connector translates the standard format action into a data-specific action that changes data in a data store. A data connector then sends a standard format data representation corresponding to the changed data back to the UI connector to provide the changed data to the UI.

摘要:
A versioning policy included in a target component indicates how the target component is to be accessed, for example, either as a library component or a platform component. A component may be designated as a library component when it is not versioned in a binary compatible manner. When other components request such a component they receive specifically the version of the component they requested. On the other hand, a component may be designated as a platform component when it is versioned in a binary compatible manner. When other components request such a component they may receive the latest upgraded version of the component requested instead. Thus, access to an appropriate version of the component (even a version differing from the requested version) is facilitated. Other embodiments include mechanisms for stratifying component scope based on different processing levels.

A dynamic, lazy type system is provided for a dynamic, lazy programming language. Consequently, programs can benefit from runtime flexibility and lightweight notation in combination with benefits afforded by a substantial type system.

The present invention extends to methods, systems, and computer program products for accessing and manipulating data in a data flow graph. A data flow graph includes one more transforms for transforming data from one or more data stores into different formats accessible to clients. Transforms can be configured to join and split data from the same or different data stores. A metadata tree logically represents the data flow graph including locations that provide output from transforms of the data flow graph. The locations can be referenced by clients to access transformed outputs. Clients can register dependencies on data at various locations and can request evaluation of the data in response to data changes at a corresponding data store. Clients can also request data changes be propagated back through the data flow graph to one or more data stores and implemented at the one or more data stores.

Methods, systems and computer products are provided for partitioning software application components into separate domains called concurrency domains. Computationally expensive, slow or long-running methods may be deployed into such domains, thus keeping the associated application more responsive to the end user. According to one aspect of the invention, a given concurrency domain is a partition of runtime objects for providing synchronization and thread isolation within the partition and for providing concurrency with other such partitions in a data-driven dynamically composed and reconfigured application.

摘要:
An execution strategy is generated for a program that interacts with data from multiple heterogeneous data sources during program execution as a function of data source capabilities and costs. Portions of the program can be executed locally and/or remotely with respect to the heterogeneous data sources and results combined.
