In Oracle 10gand above, there are a couple of new optional file types that are used by Oracle to facilitate faster backup and faster recovery operations. These two new files are Change-tracking file: This file facilitates a true incremental backup of Oracle data. It does not have to be located in the Flash Recovery Area, but as it relates purely to database backup and recovery, we ll discuss it in the context of that area. Flashback log files: These files store before images of database blocks in order to facilitate the new FLASHBACK DATABASE command.

If the call to the web service completes successfully, then the result is passed back to the onComplete function, in this case, the calculated value of the car. If it fails, an error object is passed to the onError function. The message associated with the error can be obtained by calling the object s get_message method. Figure 3-14 shows the application calculating the value of a 2005 Honda Pilot at $36,000, and the method onComplete displaying the results.

For instance, the primary base classes intended for use by business developers go into the Csla namespace itself. They are named as follows: Csla.BusinessBase(Of T) Csla.BusinessListBase(Of T, C) Csla.ReadOnlyBase(Of T) Csla.ReadOnlyListBase(Of T, C) Csla.NameValueListBase(Of K, V) Csla.CommandBase The rest of the classes and types in the framework are organized into the remaining namespaces based on their purposes. You ll see how they all fit and are implemented in s 3 through 5. The end result is that a typical business developer can simply use the Csla namespace as follows: using Csla; and all the developer will see are the classes intended for use during business development. All the other classes and concepts within the framework are located in other namespaces, and therefore won t appear in IntelliSense by default, unless the developer specifically imports those namespaces. When using custom authentication, you ll likely import the Csla.Security namespace. But if you re not using that feature, you can ignore those classes and they won t clutter up the development experience. Similarly, Csla.Data and Csla.Validation may be used in some cases, as you ll see in 8. If the types they contain are useful, they can be brought into a class with an Imports statement; otherwise, they are safely out of the way.

<xs:element name="Customer"> <xs:complexType> <xs:sequence> <xs:element name="CustomerName" type="xs:string" /> <xs:element name="CustomerAddress" type="xs:string" /> <xs:element name="CustomerCSZ" type="xs:string" /> <xs:sequence> <xs:complexType> <xs:element>

Next, update drawView to reflect the change, as shown in Listing 6-8.

The Windows Azure SDK development environment includes out-of-the-box development storage, a utility that simulates the storage services available in the cloud. The Azure SDK provides the development storage services to allow developers to create, debug, and unit test the cloud data service on a local machine before they deploy their application to production. By default, development storage relies on a SQL Server Express database, either the 2005 edition or the 2008 edition, to simulate the storage environment in the cloud. It s possible to use the full SQL Server as we ll see next, but to use SQL Server Express, you must have it installed. You also need to install SQL Server Management Studio to manage SQL Server Express. Development storage connects to SQL Server Express by using Windows authentication. To switch from SQL Server Express to SQL Server 2005 or 2008, you need to modify the configuration file, DevelopmentStorage.exe.config, and one line in the DevtableGen.exe.config file, as shown in Listing 1-1 and Listing 1-2. These configuration files are located in the bin directory of Windows Azure as shown in Figure 1-1.

Operating systems and runtimes typically provide some form of isolation between applications running on the system. This isolation is necessary to ensure that code running in one application cannot adversely affect other, unrelated applications. In modern operating systems, this isolation is achieved by using hardware-enforced process boundaries, where a process, occupying a unique virtual address space, runs exactly one application and scopes the resources that are available for that process to use. Managed code execution has similar needs for isolation. Such isolation can be provided at a lower cost in a managed application, however, considering that managed applications run under the control of the common language runtime and are verified to be type-safe. The runtime allows multiple applications to be run in a single operating system process, using a construct called an application domain to isolate the applications from one another. Since all memory allocation requested by an application is done by the CLR, it is easy for the CLR to give an application access to only those objects that were allocated by the application and to block the application s attempts to access objects allocated in another application domain. In many respects, application domains are the CLR equivalent of an operating system process. Specifically, isolation in managed applications means the following: Different security levels can be assigned to each application domain, giving the host a chance to run the applications with varying security requirements in one process.
