Introduction to ADO.NET
Entity Framework
Microsoft is launching some exciting technologies in 2008 in concert with version 3.5 of the .NET framework. Language Integrated Query (LINQ) and the ADO.NET Entity Framework will improve the developer’s ability to manage application data in an object-oriented fashion.
This paper describes what these technologies do well - and how they fall short of what enterprise application developers actually need.
DevForce EF , which will ship in conjunction with Microsoft's .NET 3.5 launch, addresses these limitations head on. This new platform extends Entity Framework by adding features for object mapping, multi-tier applications, security, performance, model design and code generation, multiple data sources, Web Services, and offline applications.

LINQ and the DevForce
Entity Framework
Microsoft is launching some exciting technologies in 2008 in concert with version
3.5 of the .NET framework. Language Integrated Query (LINQ) and the ADO.NET Entity
Framework will improve the developers ability to manage application data in object-oriented
fashion.
This paper describes what these technologies do well - and how they fall short of
what enterprise application developers actually need.
DevForce version 4.0 , whose release will coincide with Microsoft's .NET 3.5 launch,
addresses these short falls head on. It starts by leveraging and extending them
with the DevForce to Entities query language and the DevForce Entity Framework.

Developer Brief
This provides you with an overview of DevForce's powerful .NET framework. This document
will enhance your understanding of the key features of the DevForce framework and
highlights their value to enterprise application development.

Object Relational
Persistence in .NET
In this article, we orient you to Object Relational Persistence (ORP)
and then build an Employee Viewer application using IdeaBlade and .NET. We show
that it's easy to test your ORP business model so you can get in step with "test-driven
development (TDD)".
You don't have to write your own persistence layer. You can use Object Relational
Persistence (ORP) to turn relational database data into business objects and jump
straight to building your application.

Business Object
Server
A middle-tier server that deploys business objects in an n-tier environment and
allows enterprises to easily build scalable and secure Internet applications that
also work off-line. IdeaBlade's Business Object Server is a high-performance, scalable
application that can support the performance requirements of the most demanding
enterprise environment.

Business
Object Server Performance Brief
This short brief describes the performance features included in the DevForce framework
and Business Object Server, and describes the results of performance testing using
the BOS with a SQL Server database and a cluster of smart client PCs.
