Example 16 A person needs to catch a plane and is running late. She stops a taxicab and says, Take me to the airport. Along the way, traffic conditions change considerably. In fear of missing her flight, the passenger asks the driver, How much more time do you think the ride will take The cab driver answers, Probably another 20 minutes. The passenger acts as the caller, the driver as the callee. The trip to the airport represents the asynchronous execution of a command. The passenger uses a polling technique to get progress reports back from the cab driver during the trip. Example 17 A person surfs the Internet with a Web browser. He clicks the hyperlink on one HTML

Embedded SQL statements are data definition language, data manipulation language (DML), and transaction-control statements (such as OPEN, CLOSE, FETCH, and EXECUTE) used in a procedural language program, such as the statements used with the Oracle precompilers.

The data manipulation language statements are statements that either query (retrieve) or manipulate (change) data in a table. For the most part, DML statements modify the data in the schema objects. In most online transaction processing (OLTP) systems, the bulk of Oracle s work consists of accepting requests from users that contain DML statements and returning the results of those statements. You ll deal with four important DML statements most of the time: SELECT, INSERT, UPDATE, and DELETE. Note that in addition to these four common DML statements, there are others that facilitate the execution of the four basic DML statements. For example, the MERGE statement deals with conditional inserts and deletes, and you use the LOCK TABLE statement to modify the default Oracle locking mechanism.

document to go to another document. Inside the browser, the HTML rendering component (HtmlCom) issues a GetDocument command to the HTTP communication component (HttpCom), as shown in Figure 9-14. While HttpCom loads the requested page, HtmlCom issues a series of GetProgress queries to HttpCom. HtmlCom uses the information to display a progress bar on the user s screen to give an indication of how long the load process will take.

SELECT statements are queries that retrieve data from a table or a set of tables (or views). Oracle provides set operators, such as UNION, MINUS, and INTERSECT, that enable you to combine the results of several queries to get one final result set of data. You can use the ORDER BY command to sort the results provided by Oracle; otherwise, the results will not be in any particular order. When you need data from several tables, you need to join the tables in your SELECT statements. You can limit the result set when you join tables by providing a join condition. You can also use subqueries as part of the main or top query. A subquery in the WHERE clause of a SELECT statement is called a nested subquery. A subquery that is part of the FROM clause of a SELECT statement is called an inline view. The Appendix provides examples of subqueries, nested subqueries, and inline views.

Context A process P1 wishes to send a command to a process P2. While the command is being executed, certain conditions can arise that require P1 to cancel the command before it is completed. Forces Many systems require the ability to adapt to unusual or unreliable situations. If P1 detects certain conditions during the execution of a previously issued command, it may need to cancel the command and resort to an alternative course of action.

Obviously, you need to be concerned about the high rates of parsing, even though most of the parses are soft parses. The next section shows you what you can do to reduce the amount of parsing in your database.
