Sample text

The Data Access layer does nothing but move the data into and out of the database, as shown in Figure 1-10. qxd 2/27/06 12:44 PM Page 19 CHAPTER 1 ■ DISTRIBUTED ARCHITECTURE Figure 1-10. Validation and business logic in the Data Management tier The advantage of this approach is that the logic is centralized, but the drawbacks are plentiful. For starters, the user experience is totally non-interactive. Users can’t get any results, or even confirmation that their data is valid, without round-tripping the data to the database for processing.

Ideally, this business logic will run on the same machine as the UI code when interacting with the user, but on the same machine as the data access code when interacting with the database. ) It must provide a friendly interface that the UI developer can use to invoke any validation and manipulation logic, and it must also work efficiently with the Data Access tier to get data in and out of storage. qxd 2/27/06 12:44 PM Page 21 CHAPTER 1 ■ DISTRIBUTED ARCHITECTURE Figure 1-13. Business logic centralized in the Business Logic layer The tools for addressing this seemingly intractable set of requirements are mobile business objects that encapsulate the application’s data along with its related business logic.

Data access gets its own logical layer for much the same reason that the presentation is split from the UI. In some cases, data access will occur on a machine that’s physically separate from the one on which the UI and/or business logic is running. In other cases, data access code will run on the same machine as the business logic (or even the UI) in order to improve performance or fault tolerance. ■Note It may sound odd to say that putting the data access layer on the same machine as the business logic can increase fault tolerance, but consider the case of web farms, in which each web server is identical to all the others.
