| 20110246536 | METHOD AND APPARATUS FOR MAPPING OBJECTS TO MULTIPLE TABLES OF A DATABASE - The present invention creates a model that maps object classes in an object-oriented environment to a data source. The model maps the relationship between properties of each object class and data of the data source. The present invention can be used with a data source such as a relational database, user interface, file system, or object-oriented database. An application's object classes and data source schema are designed independent of the other since the model can be used to map one to the other. The model is comprised of entities and attributes. An entity maps to an object class and to at least one table of the DBMS. An entity contains attributes either simple or derived. A simple attribute maps to a DBMS column. A derived attribute is a combination of other attributes and does not directly map to a DBMS column. A relationship creates a link between entities of the model. A relationship can be used to flatten an attribute or flatten a relationship. A flattened attribute is an attribute of one entity that is added to another entity. A flattened relationship is created by the elimination of intermediate relationships between two entities. Relationships can be either unidirectional or bi-directional. A unidirectional relationship has a single traversal path that has a source entity and a destination. A bi-directional relationship has two traversal paths. A reflexive relationship can be created using a single entity. The model is used to synchronize object properties and the data of the data source. | 10-06-2011 |
| 20110119683 | OBJECT GRAPH EDITING CONTEXT AND METHODS OF USE - The present invention comprises a novel system for managing changes to a graph of data bearing objects. In one embodiment, an object graph manager object referred to as an editing context is used to identify changes made to data bearing enterprise objects and to notify other interested objects when changes occur. As a result, data bearing objects need not themselves contain code necessary for monitoring changes. In another embodiment of the invention, the editing context is used to provide event-based “undo” capabilities. In another embodiment of the invention, each enterprise object has a primary key that is used to maintain the identification between an enterprise object instance and a corresponding database row. In another embodiment of the invention, multiple levels of editing contexts are used to provide multiple isolated object graphs, each of which allows independent manipulation of the underlying data bearing objects. | 05-19-2011 |
| 20100185940 | METHOD AND APPARATUS FOR GENERATING OBJECT-ORIENTED WORLD WIDE WEB PAGES - In the present invention, HTML elements are mapped to objects in an object-oriented environment. Classes of objects are defined for each HTML element as well as the HTML document (or page). By providing a one-to-one mapping between each HTML element and object classes, HTML documents can be manipulated programmatically. The properties of each element are stored in instance variables of the associated object. Each object class can include methods to manipulate the HTML element within an HTML document. | 07-22-2010 |
| 20090187921 | METHOD FOR PROVIDING STAND-IN OBJECTS - A method for providing stand-in objects, where relationships among objects are automatically resolved in an object oriented relational database model without the necessity of retrieving data from the database until it is needed. A “fault” class is defined, as well as fault objects whose data haven t yet been fetched from the database. An object that's created for the destination of a relationship whenever an object that includes the relationship is fetched from the database. When an object is fetched that has relationships, fault objects are created to “stand-in” for the destination objects of those relationships. Fault objects transform themselves into the actual enterprise objects—and fetch their data—the first time they're accessed. Subsequently, messages sent to the target objects are responded to by the objects themselves. | 07-23-2009 |
