The same GetMethod() call is used as in Fetch() and Delete(), but the name of the method is determined based on the type and state of the business object itself. If the business object is a subclass of CommandBase, then the method name is DataPortal_Execute. For any other objects that don t inherit from BusinessBase, the method name is DataPortal_Update. If the business object is a subclass of BusinessBase, however, the object s state becomes important. If the object is marked for deletion, then the method name is DataPortal_DeleteSelf. If the object is new, the name is DataPortal_Insert; otherwise, it is DataPortal_Update.

Oct 30, 2013 · Today, I'd like to cover how, using VB.NET, you can use the Dynamic .NET TWAIN 5.0 SDK to implement barcode reading in a WPF application. The most common measurement of availability is expressed as a number of 9s, which creates really nice buzzwords for a chief information officer (CIO), chief technical officer (CTO), or chief executive officer (CEO). However, it has very little actual basis in fact. Just because you aren t achieving five 9s of availability (99.999 percent) doesn t mean there is a problem. You could be dealing with an application that needs only 98.45 percent availability or one that needs 92.6 percent availability. The formula used to calculate availability is as follows, where A = Availability, F = Mean time between failures (MTBF), MR = Mean time to recognize, and R = Mean time to repair: A = (F (MR + R))/F The interesting thing about this formula is that you calculate availability based on fail ures and recovery. You do not have any control over failures they are simply going to happen and rarely provide any warning at all. However, you can influence the amount of time it takes to diagnose a problem, come up with a solution, and repair the system. You might be a bit puzzled at this point. This chapter is about high availability, and everyone knows that high availability is about keeping a system online.
