3) because different online services of MarvellousWorks are established at different times, the databases include ORACLE, MySQL, and SQL Server.
Now you are the architect to design the "Message Platform" service program.
1. the queue access interface and database access interface are defined as follows:
/// /// Queue access interface/// Interface IQueue{XmlDocument Peek ();XmlDocument Dequeue ();}
/// /// Base classes of online business data entities/// Abstract class EntryBase {}

Adapter mode: The interface of one class is converted into another interface that the customer wants, so that those classes that cannot work together because of incompatible interfaces can work together.such as (borrow picture):Set up the interface of the book// Book Interface Interface bookinterface{ // page Flipping method public function turnpage () ; // Open Book Method Public function open ();}// Paper Book Realization class class
of laws that can absorb the internal forces of others while not losing the internal forces of others and will absorb the skill for their own use? Oh, perhaps is looking at this article of you to invent this set of laws, will also become the same as Zhang a generation of Guru (see I said that cut ...) )。 In fact, in software design, as in the case of this story in general, for example, there is a design of Class A (there is a method of public void Aa () {}), we need to call him in the current sy

The adapter mode is a very practical design mode. This article will introduce this design mode through examples.
The purpose of the adapter mode is to convert an interface of a class to another interface that the customer wants.

When the adapter refresh data, it must be able to refresh successfully, and ensure that each refresh changes the data source.
So I did this and wrote in the constructor of the adapter:

Adapter Pattern Definition: Use two incompatible classes Jiuge, belong to the structure mode, need to have adaptee (be fit) and adaptor (adapter) two identity.
Why use Adapter mode
We often run into a combination of two classes that don't have a relationship, the first solution is to modify the interfaces of the respective classes, but if we don't have the sour
Adapter mode (Adapter pattern)IntroducedTransforms the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work together.ExampleThere is a message entity class that has the insert () and get () methods for its operat
The adapter pattern is to transform the interface of one class into another interface that the client expects, so that two classes that would otherwise not work together because of an interface mismatch can work together.An example of an adapter pattern:Please do a specific class of kittie and implement methods such as Miao (), Catchrat (), run (), sleep (), and so on. To do a puppie interface, requires WAO
Today learning another design pattern, adapter (Adapter) mode, which is a common direction, but with special requirements, is applied to this design pattern. Write here, think of a long time ago, have written an article "ASP." NET Adapter design mode (Adapter) http://www.cnblogs.com/insus/archive/2013/02/04/2891426.htm
According to the msdn webcast courses)
Adaptation: basically, the original incompatible interfaces are converted into compatible interfaces without changing the original implementations.
Gof: to convert an interface of a class to another interface required by the customer, you have to work together the classes that cannot work together due to incompatibility of the original interface.

However, as wireless Internet access technology becomes more and more popular, the "wireless Internet access" era has quietly come to our side. The desire to break through the limitations of Network cables and free Internet access anytime and anywhere has contributed to the growth of the wireless network card market. Now, whether wireless Internet access is available has become one of the main indicators for consumers to determine whether a c
Transforms the interface of one class into another interface that the customer wants. Those classes that would otherwise not work together because of incompatible interfaces can work together.
Scenario: You want to reuse some existing classes, but the interfaces are inconsistent with the reuse environment requirements.
Pattern feature: Transforms the interface of a class into another interface that the customer wants.
Classification: Class adapters (through multiple inheritance), object adapter
