As we mentioned, an inherent obstacle to ensuring the characteristics of atomicity, consistency, and durability exists because of the way a database server accesses and writes data Since the database server operates on data that is in memory, there is a danger that if a failure occurs, the data in memory will be lost, leaving the disk copy of the data store in an inconsistent state MySQL s autocommit mode combats this risk by flushing data changes to disk automatically However, as you saw, from a transaction s perspective, if one part of the transaction were recorded to disk, and another change remained in memory at the time of the failure, the atomic nature of the transaction would be in jeopardy To remedy this problem, database servers use a mechanism called logging to record the changes being made to a database.

Then click on the COM Components tab and add a check mark next to Microsoft Agent Control 20 (see Figure 22-15), and click OK This adds the agent control to the Toolbox you can then drag it onto any form and Visual Studio will automatically create the RCW The Microsoft Agent control allows you to use Merlin (a genie), Peedy (a bird), or Robbie (a robot), or all of them at once All components are complete with rotoscoped animations, can perform various actions as you direct them, can move about the screen, can think or speak text (either using a poor voice synthesizer that s included, or a wave file you specify) When speaking with a voice file, the characters mouths even move to synchronize closely with the words, creating a lifelike illusion Best of all, Microsoft gives these features away for free.

In general, logs write data directly to disk instead of to memory3 As explained in the previous chapter, the database server uses the buffer pool of data pages to allow the operating system to cache write requests and fulfill those requests in a manner most efficient for the hardware Since the database server does writes and reads to data pages in a random manner, the operating system caches the requested writes until it can write the data pages in a faster serialized manner Log records are written to disk in a serialized manner because, as you ll see, they are written in the order in which operations are executed This means that log writing is an efficient process; it doesn t suffer from the usual inefficiencies of normal data page write operations MySQL has a number of logs that record various activities going on inside the database server.

You can purchase other agent characters from third-party sites online, or create them independently, although the tools provided won t help you create lifelike animations..

Figure 22-15. Adding the Microsoft Agent control The online samples include an AgentTryout application that allows you to put an agent character through its paces, speaking and thinking the text you specify, moving about the screen, and performing various animations (see Figure 22-16).
