Beijing, Architecture amp; Design

Производитель: "daab"

Apart from being one of Asia's largest metropolises, Beijing is an ultimate visual challenge. The country's growing economy and construction boom has attracted the attention of the world's finest architects eager to create masterworks in this city. The new is rapidly replacing the old in the country's political, economic and cultural center. When Beijing won the bid in 2001 to host the 2008 Olympic Games, the city started a somewhat controversial transformation. Olympic-driven developments - from sports and cultural infrastructure to business buildings and commercial facilities - have transformed a city once characterized by conservative Communist architecture. Now the emerging Chinese middle-class can live, work and play in Westernstyle residential buildings, offices and malls, such as SOHO Shangdu and can be seen in some of the city's trendiest venues, like Philippe Starck's LAN restaurant and Zhong Song's Song Music Bar + Kitchen.

DAAB

* DAAB stands for Data Access Application Block, a Microsoft technology that is reusable and extensible source code-based guidance that simplifies development of common data access functionality in Microsoft .NET applications. Applications can use the application block in a variety of situations, such as reading data for display, obtaining data to pass through application layers, and submitting changed data back to the database system. The application block includes support for both stored procedures and in-line SQL, and common housekeeping tasks such as managing connections and creating and caching parameters are encapsulated in the application block's methods. DAAB supports the languages C# and Visual Basic .NET.

Previous versions of the DAAB were stand-alone application blocks; the new DAAB is a part of the new Enterprise Library collection of application blocks

The current release of Enterprise Library for .NET Framework 2.0 is a relatively minor update to the existing Enterprise Library DAAB. It will support the same key scenarios, but it’s been redesigned to leverage some new features in .NET Framework 2.0, and to sport a simpler architecture

The Data Access Application Block has the following features:

* It reduces the need to write boilerplate code to perform standard tasks.
* It helps maintain consistent data access practices, both in an application and across the enterprise.
* It reduces difficulties in changing the physical database target.
* It relieves developers from learning different programming models for different types of databases.
* It reduces the amount of code that needs to be rewritten when porting applications to different types of databases.

"Common Scenarios"

Developers often write applications that use databases. Because it is so common, developers may find themselves writing the same code over and over, for each application. In addition, these applications may need to work with different types of databases. Although the tasks are the same, the code must be adapted to suit the programming model of each database. The Data Access Application Block solves these problems by providing an implementation of the most common data access tasks. Developers only need to do the following:

1. Create the database object.2. Supply the parameters for the command, if they are needed.3. Call the appropriate method.

The DAAB is optimized for performance, designed for portability and it works transparently with SQL Server, DB2, and Oracle databases.

*DAAB is also the name of a most popular polish Reggae-Band/formed in 1983/ http://daabwww.w.interia.pl
