<p>A system and method for encapsulating an application program (106) is described. The system uses a concise, high-level application encapsulation and description language syntax which uses a plurality of object descriptions to encapsulate a complete application program. The application encapsulation and description language syntax is designed to concisely, or orthogonally, provide a basis of fundamental data description objects that span the data problem space of business data access programming problems. The application encapsulation language syntax uses several types of objects (306, 324), which in combination encapsulate a wide range of application programs. Graphical user interface ('GUI objects') (308) encapsulate important user interface views and functions. A set of query objects (310) populates the GUI objects with data, a set of transaction objects (312) structure the GUI objects into linked views, and a set of control objects provide additional application features. An asssociated data source (108) may also be provided. These application description objects (318) are conbined by an application shell (104) program that reads and parses one or more specification or configurations files written in the object description syntax and creates a fully-functional application program. This application program may be executed to allow access to, and manipulation of the associated data source.</p> |
