Microsoft adds to framework to simplify development

ADO.Net Entity Framework and tools to eliminate impedance mismatch are implemented to help developers build business apps

Looking to assist developers in building business applications, Microsoft published a second beta version of ADO.Net Entity Framework this week and a community technology preview of tools to work with the framework.

The goal of the ADO.Net Entity Framework is to eliminate the impedance mismatch between data models and languages, saving developers from having to deal with these. An example of such a mismatch is objects and relational stores.

Automation of complex processes is critical to the framework.

"Today, when a developer builds an application, they have to write code that fills in the gaps between the way the data is stored in however many databases they interact with and the way they want to manipulate the data in their application," said Britt Johnston, product manager for data programmability tools at Microsoft. "Generally, what they do is create an object model that they write their code against."

Developers might write an application that manipulates a CRM system with data for customers stored in 12 different tables, said Johnston.

"With the Entity Framework, you can automate the process essentially of bringing all that data together and presenting it to the developer as a single entity so they can interact with it at a higher level of abstraction," Johnston said.

Key new features in the framework beta release include events to customize code generation; complex programming types and entity key serialization. A key is a unique identifier for an entity, such as a customer ID. Metadata annotations and better support for LINQ (Language Integrated Query) also are included. LINQ features extensions to the .Net Framework to encompass language-integrated data query, set, and transform operations.

Developers can access the framework on Microsoft's Web site. ADO.Net Entity Framework is due for general release as part of .Net Framework 3.5 in early-2008. Most would get it as part of an operating system update.

The ADO.Net Entity Framework Tools Community Technology Preview for August features an early version of the ADO.Net Entity Designer, enabling users to visually design model and mappings using the Visual Studio 2008 Beta 2 release. The tools preview is accessible on Microsoft's download page with the tools to be part of Visual Studio 2008.

With the framework, developers could focus on the needs of an application instead of the complexities of bridging disparate data representations. The framework consists of a data model and design-time and run-time services that allow developers to describe application data and interact with it in a conceptual level of abstraction appropriate for business applications, according to the company. This helps isolate the application from underlying logical database schemas.

STYLISTIC Q702

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

STYLISTIC Q572

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
