Methods and apparatus, including computer program products, for using a meta model for an enterprise service architecture. The meta model includes a first class to represent data organization in a back end data store. The first class includes a data type identifier attribute to permit meta data to identify a data type. The meta model also includes a second class associated with the first class. The second class includes a field identifier attribute to permit meta data to identify fields for a particular data type. The meta model also includes a third class associated with the first class. The third class includes an action identifier attribute to permit meta data to identify an action. In some examples, there is a service provider identifier to permit meta data to identify a service provider class that can effect the action.

Meta model for an enterprise service architecture

Methods and apparatus, including computer program products, for providing to a client a definition of an object representing attributes of a first collection of data elements and an operation on the first collection, each data element having attributes and the operation in common with other data elements from the first collection, the definition comprising an effect of executing the operation on a second collection of data elements. This also includes receiving from a client a request to execute the operation on one or more data elements from the first collection, executing the operation on one or more data elements from the first collection, and updating a copy of one or more data elements from the second collection according to the effect of executing the operation.

Side-effect modeling

Systems, methods, and computer program products are provided for adapting service entities using a declarative approach in a service framework. In accordance with one implementation, a method is provided for adapting service entities. The method includes the steps of retrieving at least one software entity from a first repository in response to a first input and receiving a declaration from a user for adapting the software entity. The method further includes the steps of adapting the software entity to an adapted software entity based on the declaration and storing the adapted software entity in a second repository.

Service adaptation of the enterprise services framework

Methods and apparatus, including computer program products, for providing services by an application server, the method including collecting a request from a consumer software component for a service from a provider software component, and checking the request against a set of semantic descriptions in a manifest of methods provided by objects in the provider software component.

Service management of a service oriented business framework

Methods, systems and computer program products implementing techniques for using interrelated data at run time. The techniques include establishing a model, the model implementing application logic of an application; establishing at least one view for presenting the model; establishing at least one controller for manipulating the model; and establishing at least one storage area, the storage area relating to the controller and storing an instance of a first data structure, the instance of the first data structure comprising application data having been stored in the storage area by an access method, the first data structure having been declared prior to execution of the application.

Using interrelated data at run time

Methods, apparatus, and computer program products that implement techniques for extending the MVC design pattern by structuring data of an application into application contexts. The techniques feature accessing a predetermined structure for a storage area, modifying the predetermined structure and creating an instance of the storage area according to the predetermined structure. The storage area relates to a controller. The controller is operable to manipulate a model and a view. The view includes multiple UI elements for presenting data from the model. The predetermined structure includes multiple design-time context elements and relationships between the design time-context elements. At least one of the UI elements is bound to one of the design-time context elements. The instance of the storage area includes multiple run-time context elements. Each run-time context element corresponds to one of the design-time context elements.

Dynamic contexts

Methods and apparatus, including computer program products, that include representing, in a repository, services from a server, the services including interacting with one or more collections of data elements using a set of operations on the data elements in the collections, the repository comprising descriptions of the collections and common attributes for each collection, the repository organized according to a meta model. The method also includes enabling a software entity to request a service represented in the repository, the service representing a first operation on one or more data elements in a first collection from the collections, and executing the first operation on the one or more data elements in the first collection.

Self-describing business objects

Methods and apparatus, including computer program products, for implementing a computer system that provides a model, a first view and at least a second view for presenting the model, a first controller and at least a second controller for manipulating the model. The first and second views relate to the first and second controllers, respectively. The computer system further comprises at least a first context, a second context and a third context. A user interface element of the first view binds to a first structure element of the first context and a user interface element of the second view binds to a second structure element of the second context. The first structure element and the second structure element reference a third structure element of the third context.

Using relationships between contexts in model view controller design pattern

Methods and apparatus, including computer program products, implementing techniques for declaring application data. The techniques include establishing a model, the model implementing application logic of an application; establishing at least one view for presenting the model; establishing at least one controller for manipulating the model; establishing at least one storage area, the storage area relating to the controller; and establishing at least one access method for storing and accessing application data in the storage area according to a predetermined structure.
