I'll also direct you to material that more thoroughly explains particular concepts, VBScript commands, and so forth Although I'm not a big fan of flipping back and forth through a book, these cross-references will allow you to remain focused within each chapter and will guide you to more detailed explanations, when appropriate Finally, there are times when it is necessary to present an extended explanation of something that isn't critical to the task at hand In those cases, I'll use a sidebar A sidebar is a cue that the information is useful, but it's not really key to the main text; you're welcome to skip the sidebar and come back to it later if you like

each table that holds the primary key This is not necessarily a bad thing, but it means that you must look up the data type and column name whenever you want to add another column with a foreign key or you need to write a piece of code to join tables Wouldn t it be nice if all your tables had their PKs in columns having the same name For example, every table in your database could be given a column named objectid and that column could simply have an arbitrary unique integer In this case, you can use an identity column in SQL Server to manage your integer PK value An identity column is one that automatically increments a number with each insert into the table When you make a column an identity, you specify a seed, or starting value, and an increment, which is the number to add each time a new record is added Most commonly, the seed and increment are both set to 1, meaning that each new row will be given an identity value that is 1 higher than the preceding row Another option for an arbitrary PK is a GUID GUIDs are most often used as PKs when you need to copy data between databases and you need to be sure that data copied from another database does not conflict with existing data If you were instead to use identities, you would have to play with the seed values to avoid conflicts; for example, the number 1,000,454 could easily have been used in two databases, creating a conflict when the data is copied The disadvantages of GUIDs are that they are larger than integers and they are not easily readable for humans Also, PKs are often clustered, meaning that they are stored in order Because GUIDs are random, each time you add data it ends up getting inserted into the middle of the PK, and this adds overhead to the operation In 10 we talk more about clustered versus nonclustered PKs Of all the PK options we have discussed, we most often use identity columns They are easy to set up and they provide consistency across tables No matter what method you use, carefully consider the pros and cons Implementing a PK in the wrong way not only will make it difficult to write code against your database but also could lead to degraded performance.

Control objects are used for controlling content-type-specific media processing operations The set of operations are usually functionally related Thus a Control object provides a logical grouping of media-processing functions

All Control classes implement the interface Controllable, and the Player interface is a subinterface of Controllable Therefore, a Player implementation can use the Control interface to extend its media-processing functions For example, a Player can expose a VolumeControl to allow the volume level to be set

As with primary keys, foreign keys in SQL Server work in the same way as they do in logical design A foreign key is the column or columns that correspond to a primary key and establish a relationship Exactly the same columns with the same data as the primary key exist in the foreign key It

Sidebars make it easier to cover slightly off-topic information without distracting you from the main text

The javaxmicroeditionmediacontrol package specifies a set of predefined Controls classes In MIDP 20, two controls are specified and required: ToneControl and VolumeControl
