For certain types of applications, it is necessary to keep track of all the functions that were performed. Consider an application that calculated the interest for all of the accounts in a bank. The transaction being performed causes money to be transferred from the bank s account to the consumer s. And a problem will cost the bank money, the consumer aggravation, or both. For transactions such as this, the corporate auditors are going to want detailed information about which value was put where. But financial auditing isn t the end of the auditing function. Laws such as HIPAA and Sarbanes-Oxley mandate auditing of certain types of transactions. And although these laws apply only to the United States, there might be a need to comply if you plan on doing business in the United States. Not to mention that a growing number of other countries are introducing their own legislation that covers the same area.

When the PrintDialog component is shown, the user can make changes to the config uration of the print job by setting options that are displayed in the PrintDialog box. You can restrict the options displayed by modifying the properties of the PrintDialog component.

Complex IIS servers might host tens of thousands of sites, each with customized settings to make them tick. Losing all that configuration information could be painful, so although a normal file system backup might allow you to restore the data files after a failure, the configuration would be lost. To back up or restore IIS configuration, you must back up or restore the metabase and the schema, Extensible Markup Language (XML) documents that are used to store settings. To manually back up the IIS configuration, complete the following steps: 1. Right-click the server node in IIS Manager and, from the All Tasks menu, choose Backup/Restore Configuration. Click Create Backup. When prompted, enter a name for the backup and click OK. The metabase and schema are backed up to the directory %Windir%\System32 \Inetsrv\Metaback. 2. Use any backup procedure to back up the contents of the Metaback directory.

In Report Manager, on the Home page, click the Report Builder button. When Report Builder opens, select the AdventureWorksDW2008 model on the right. Select Tabular format, and then click OK.

To deploy the report, on the File menu, select Save As to open the Save As Report window. In the Look In drop-down list, select the http://localhost:8080/Report Server/ TK 448 Ch11 SSRS Deployment folder. Type products categories as the report name, and then click Save.
