摘要:
A map provider and a data location provider provide information as to how the data pertaining to entities is stored in a database system and where the data is stored in the database system. A data accessing system uses the information to process requests to perform an operation on the data.

A user interface can be maintained in a responsive state on a user interface thread while synchronous application logic is running on a background thread. The application logic can access an object on the background thread, and the user interface can access the same object on the user interface thread. Additionally, a request for work to be done on an object can be received. If the request is to be dispatched to a background thread, then the work can be dispatched to the background thread without blocking the user interface thread. However, if the request is to be dispatched to the user interface thread, then the work can be dispatched to the user interface thread, and the background thread can be blocked.

Join expressions, expressed in terms of objects, are translated into a relational database join statement by generating a parse tree based on the join expression. The parse tree is traversed to build the relational database join statement.

A method and system for storing and retrieving data in an object-relational database system includes receiving a query which results in a request to load a first object. The method also includes identifying relationship types of other objects having a relationship with the first object. Then, the first object and those of the other objects which have a composition relationship with the first object are eager loaded. Those of the other objects which have an association relationship with the first object are marked as fault on demand. Preventing re-faulting of the same object in the same object graph, and trimming of graphs for serialization are also provided.
摘要:
A dynamic filtering module receives a request to perform an operation on data in the database and a input. The dynamic filtering module provides as an output a modified request to a data access system. The modified request can include one or more restrictions added to the original request pertaining to which data will be accessed as a function of the input.
摘要:
A programming model for customized data objects is provided. For several embodiments, a method for providing customizable data objects comprises storing an abstract definition of an entity in metadata, the definition including a set of properties of the entity; and generating an entity view class based on the set of properties of the entity and including at least one property of the entity in the entity view. When programming against the entity view class, only those properties included in the entity view class are allowed to be seen or modified.
摘要:
Process is integrated into a business application framework on which the process is built. The same programming model used by the framework is used for managing data operated on by the process and for interacting with and controlling the process.
摘要:
A business software framework includes an application framework that has a process model. The process model provides desired services to the business components. The process model arranges operations into activities. The process model can also use an agent/service arrangement.
