Database management systems need to persist data across restarts of the server. This means that persistent media must be used to store the data. This persistent media is commonly called the hard disk or secondary storage. A hard disk is composed of a spindle, which rotates a set of disk platters, at a certain speed (commonly 7,500 rpm or 15,000 rpm). Each disk platter is striped with a number of tracks. These tracks are markers for the disk drive to move a data reader to. This data reader is called the arm assembly, and contains disk heads, which move to and from the outside of the platters toward the spindle, reading a sector of the disk at a time. See Figure 2-1 for a visual depiction of this structure.

void makeBox(float width, float height, float depth) xDim = width/2.0f; yDim = height/2.0f; zDim = depth/2.0f;

Because we use using URIs to navigate, we can take advantage of their query string capabilities and pass additional data as part of the URI itself These work using exactly the same technique as query strings in a URL in a web browser The beginning of the query string is indicated by adding a question mark to the URI; it is then followed by any number of name/value pairs formatted as the name, then an equals sign, and then the value If multiple parameters are being passed, an ampersand is used to separate them For example, to pass a name and a score to a page named Scoresxaml, we could construct a URI as follows: Scoresxaml Name=Player name&Score=12345 Those of you familiar with using query strings for web navigation will be aware of the need to encode values that are passed in query strings.

Figure 2-1. The hard disk On the hard disk, data is arranged in blocks. These data blocks can be managed as either a fixed or variable size, but they always represent a multiple of the fixed size of the sector on disk. The cost of accessing a block of data on a hard disk is the sum of the time it takes for the arm assembly to perform the following steps: 1. Move the disk head to the correct track on the platter. 2. Wait for the spindle to rotate to the sector that must be read. 3. Transfer the data from the start of the sector to the end of the sector.

If the user entered the name as Adam & Joe , the resulting query string would be as follows: Scoresxaml Name=Adam & Joe&Score=12345 In this case, the ampersand in the name will confuse the query string It will consider the name to be Adam (with a trailing space); it will then find an unexpected keyword that it doesn t know how to handle ( Joe , with a leading space), and then finally it will find the score (which it will process correctly) The result of this is that retrieving the name from this query string will return just Adam ; the rest of the name will be lost This is easily solved by using a Silverlight function that will encode strings for inclusion into URLs and URIs The HttpUtilityUrlEncode function does this perfectly The resulting URI, once the name has been encoded, is the following: Scores.

Appearance app = new Appearance();

Of the total time taken to access or write data to the disk, the first and second operations are the most costly. All of this happens remarkably quickly. The exact speed mostly depends on the speed at which the spindle rotates, which governs the time the assembly must wait for the sector to be reached. This is why disks with higher rotations per minute will read and write data faster.

xaml Name=Adam+%26+Joe&Score=12345 The + characters will be interpreted by the navigation engine as spaces, and %26 will be decoded to the character whose ASCII value is identified from the hexadecimal number 26 (which results in an ampersand) None of these characters causes any problem when Silverlight parses the query string, however, so the value passes through navigation undamaged Listing 12 24 shows the code from the Hello button in the example project It navigates to the NamePage, passing whatever name the user has entered as a parameter The name is encoded to ensure that it doesn t cause any problems in the query string Listing 12 24 Navigating to a new page and passing a parameter private void buttonSave_Click(object sender, RoutedEventArgs e) { // Navigate to the Name page NavigationServiceNavigate( new Uri("/NamePagexaml YourName=" + HttpUtilityUrlEncode(textNameText), UriKind.
