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.

Chapter 7 discusses how to design a relational database schema based on a conceptual schema design. This chapter presented a high-level view of the database design process, and in this chapter we focus on the logical database design or data model mapping step of database design. We present the procedures to create a relational schema from an Entity-Relationship (ER) or an Enhanced ER (EER) schema.
