Abstract: A method and system for creating and modifying computer applications using an application description language based on a markup language is provided. An engine creates, connects, and initializes objects corresponding to entities, and specified by entity tags. A factory may be specified by an entity tag and used to create a plurality of entities. Applications are specified in a plaintext descriptive language using a markup language such as XML, enabling applications to be easily developed using object oriented techniques and abstraction. Altering preexisting applications is also simplified. Finally, an application may be dynamically reconfigured when the application's data changes. Type checking and conditional creation of entities is supported.

Abstract: A framework is implemented. The framework is configured to execute an application within the framework, the application includes instantiated runtime objects. New instantiated runtime objects may be created and instantiated runtime objects destroyed while the application is executing. The framework is further configured to implement a debugger within the framework. At the debugger, instantiated runtime objects are correlated with lines of code of the application. Some embodiments allow users to debug executing applications. This can be accomplished by a user interacting with the executing application which then causes indications in the debugger or interacting with the debugger and which causes indications on instantiated runtime objects in the application.

Abstract: Embodiments described herein are directed to the constructing software applications based on data models and automatically reconfiguring runtime object graphs according to data model edits input by a user. In one embodiment, a computer system performs a method for constructing at least a portion of a software application based on a data model. The computer system accesses a data model that includes user-configurable construction information indicating how at least a portion of a software application is to be constructed. The declarative interpreter is configured to construct an application based on the construction information in the data model. The computer system interprets the construction information in the data model to determine how to construct at least a portion of the software application. The computer system also constructs at least a portion of the software application based on the interpretation of the construction information in the data model.
