is easy to understand, if you are not happy with some data modifications, You Want To 'undo 'it: rollback.The original (non modified) information within a transaction is stored in a separate undo tablespace, because the database is designed for commit to be fast, not rolling back.Read consistency Another mechanic undo information is used for is read consistency, which means if you run a query at for 10 minutes, you want all the data to be from. you d

The most basic requirement for program robustness is the processing and capturing of program errors. in ASP. NET, the error processing mechanism is the same as that in other programming languages. You can use Try... Catch... Finally and so on, which is greatly improved compared with ASP. In addition, using these error handling methods can greatly improve the readability and debugging speed of the program. When combining these advantages, we should pay more attention to this.For error handling, r

From: http://mylifewithandroid.blogspot.com/2009/06/controlling-application-separation.html I thought I knew how application separation in Android works. Then I hadLittle project and I realized that there is more than meets the eye. Here are myExperiences. The basic-and very efficient-Separation Method inAndroid is the Multiprocess capability of the Dalvik VM. Dalvik is able to forkMany instances of itself and can run applications in different Linux processes.By default, each application (Appli

Now any additional code anywhere in your application can attach additional functionality to be executed when a new user registers.Attaching events Continuing with the example, let's see how attach an event's callback. I 've attachingsendMyEmail()Method toonUserRegisteredEvent so now when a new user registerssendMyEmail()Function will be called. Alternatively, in PHP 5.3 or greater you can specify an anony

See section 26.5.2. 26.5.1 vectored-event Injection VM entry delivers an injected vectored event within the guest context established by VM entry. This means thatDelivery occurs after all components of guest State have been loaded (including MSRs) and after the VM-executionControl fields have been establis

While doing Android programming, it's a common sense to use activity to interact with users and use service to perform time consuming tasks (actually, such tasks are usually saved med on a new thread spawned by the service ). A classic example is media player. it's composed of several activities and a playing-back service. through activities, users can pick a media file to play, or control (START, pause, fast forward, set volume, etc) the playing-back service. and the service is responsible for
