In the example depicted by figure 1.5, the requirements have been separated in terms of horizontal and nonfunctional requirements. That is, the databases have been separated into integration concerns, online transactional concerns, and reporting concerns. Both the integration database and the reporting database interface with the transactional system via a batch load, which implies that for this system it is acceptable to have reports that are not exactly up-to-date and that the transactional database only requires periodic updates from third-party systems. The advantage is that the transactional system has a great deal of load lifted from it and can have a simpler design as well. Generally it is not practical to design a database that is efficient for integration, transactions, and reporting. There are patterns for each that ensures the best performance and design. However, it is sometimes a requirement to have near real-time integration and reporting functions. For that reason this kind of design may not work. You might instead find that your enterprise database has to be partitioned vertically by business function. Regardless of your enterprise database design, it s easy to appreciate the difference between an application database and an enterprise database. It s important to understand the particular limitations of your environment to ensure that your application uses the database effectively and is a good neighbor to other applications that are using the same database.

Classpath This section deals with classpath issues within your build file. 45. Use explicit classpaths wherever possible. Although some libraries must be in ANT_HOME/lib, keep the ones that are not needed there in a separate location, and refer to them with Ant properties to allow for overriding. Avoid, if possible, using filesets to pull *.jar into a path declaration, as this makes the build file break if conflicting JAR files are added later.

Solution to Exercise 15-3. Take the following famous string:

Common Assembly-Language Constructs Up to this point, I've just been covering basic assembly-language instructions Now I want to start looking at various assembly-language constructs that you'll encounter and explain how you identify them and translate them into higher-level operations FS Register Access In Win32 operating systems, the FS register is special because the pointer to the thread information block (TIB) is stored in it The TIB is also called the thread environment block (TEB) The TIB holds all the thread-specific data so that the operating system can keep your thread access straight This thread-specific data includes all the structured exception handling (SEH) chains, thread local storage, the thread stack, and other information needed internally For more information about SEH, see 13 For an example of thread local storage, see the MemStress discussion in 17.

Animations2 are more complicated than other Android resources, but they re also the most visually impressive. Android allows you to define animations that can rotate, fade, move, or stretch graphics or text. Though you don t want to go overboard with a constantly blinking animated shovel, an initial splash or occasional subtle animated effect can enhance your UI. Animation XML files are placed in the res/anim source directory. There can be more than one anim file, and, as with layouts, you reference the respective animation you want by name/id.
