  • Microsoft’s ADO.NET Entity Framework, known widely as EF, introduced out-of-thebox Object Relational Mapping to .NET and Visual Studio. Central to Entity Framework was the Entity Data Model, a conceptual model of your application domain that maps back to the schema of your database. This conceptual model describes the core classes in your application. Entity Framework uses this conceptual model while querying from the database, creating objects from that data and then persisting changes back to the database....

  • The module uses client-side examples to illustrate the various aspects of DOM, but you should point out that DOM can be used equally well on the server. Students will use DOM on the server during Module 8, ìValidating XML Data Using Schemas.î Before beginning this module, you should ask students if they are already familiar with another object model. (Any object model will do.) Prior exposure to an object model makes it much easier to understand issues such as inheritance, methods and properties, and creating objects in Microsoft VBScript. ...

  • Databases and database systems are an essential component of life in modern society: most of us encounter several activities every day that involve some interaction with a database. For example, if we go to the bank to deposit or withdraw funds, if we make a hotel or airline reservation, if we access a computerized library catalog to search for a bibliographic item, or if we purchase something online—such as a book, toy, or computer— chances are that our activities will involve someone or some computer program accessing a database.

  • The Self-Organizing Map (SOM) is a neural network algorithm, which uses a competitive learning technique to train itself in an unsupervised manner. SOMs are different from other artificial neural networks in the sense that they use a neighborhood function to preserve the topological properties of the input space and they have been used to create an ordered representation of multi-dimensional data which simplifies complexity and reveals meaningful relationships. Prof. T. Kohonen in the early 1980s first established the relevant theory and explored possible applications of SOMs. ...

  • Asmentioned in the introduction, the information associatedwith an event is represented by a data structure called a notification.We refer to the datamodel or encoding schema of notifications as the event notification model or simply event model. Most existing event notification services adopt a simple record- like structure for notifications, while some more recent frameworks define an object-oriented model (e.g., the Java™ Distributed Event Specification [Sun Microsystems 1998] and the CORBA Notification Service [Object Management Group 1998b]).
