In the preceding section, you learned that a remote object must be activated prior to consuming it. The term activation refers to how the objects are created and maintained on the server. There are two ways in which the remote objects can be activated: Server-activated objects: The lifetime of these remote objects is controlled by the server. These objects have a unique name (Uniform Resource Identifier, or URI) on the network and are often called well-known objects. Server-activated objects can be further classified as singleton or single call. In the case of singleton objects, the server maintains only one instance of the remote object. The same instance serves all the clients. In other words, all the clients share the same object. In the case of single-call objects, the server creates and destroys an object on a per-call basis. That means each method call gets its own instance to work with. After the method completes, the instance is destroyed. Client-activated objects: The lifetime of these remote objects is controlled by the client application. For each client, a separate object instance is created and maintained on the server. It is worth noting that server activation is recommended for stateless objects, whereas client-side activation is good for stateful objects.

The stored procedures are stored internally in the database and can be called from external programs. In your architecture, the stored procedures will be called from the business tier. The stored procedures in turn manipulate or access the data store, get the results, and return them to the business tier (or perform the necessary operations). Figure 2-5 shows the technologies associated with every tier in the three-tier architecture. SQL Server contains the data tier of the application (stored procedures that contain the logic to access and manipulate data) and also the actual data store.

Although coding and naming standards might not seem that important at first, they definitely shouldn t be overlooked. Not following a set of rules for your code almost always results in code that s hard to read, understand, and maintain. On the other hand, when you follow a consistent way of coding, you can say your code is already half documented, which is an important

Previously you learned that the proxy marshals data across the client and server over a channel. Thus a channel is responsible for carrying method calls and data across the network. The .NET Framework provides three built-in channels: Transmission Control Protocol (TCP), Hypertext Transfer Protocol (HTTP), and interprocess communication (IPC).

contribution toward the project s maintainability, especially when many people are working on the same project at the same time.

The marshalled data must be sent in a certain understandable format. This is the job of formatters. The .NET Framework comes with two formatters out of the box: a binary formatter and a SOAP formatter.

Tip Some companies have their own policies regarding coding and naming standards, whereas in other

cases you ll have the flexibility to use your own preferences. In either case, the golden rule to follow is be consistent in the way you code.

Note Recollect that in 8 you learned about serialization formats. The remoting framework internally uses the same serialization classes for marshalling the data.

Naming conventions refer to many elements within a project, simply because almost all of a project s elements have names: the project itself, namespaces, Web Forms, Web User Controls, instances of Web User Controls and other interface elements, classes, variables, methods, method parameters, database tables, database columns, stored procedures, and so on. Without some discipline when naming all those elements, after a week of coding, you won t understand a line of what you ve written. This book tries to stick to Microsoft s recommendations regarding naming conventions. We ll talk more about naming conventions while building the site.

By default the TCP channel uses a binary formatter, whereas the HTTP channel uses a SOAP formatter. However, this coupling is by no means rigid. You can use SOAP over TCP and binary over HTTP if you so wish. You can even develop custom channels and formatters.
