6. Always log error (and backtrace) before re-raising the exception.
 
02:28
When you re-raise an exception, you will reset the backtrace (the track back to the line on which the error was raised) and might change the error code (if you raise a different exception to propagate the exception "upwards"). So it is extremely important to call you error logging subprogram (see previous Good to Know) before you re-raise an exception.

How to Handle Exceptions Properly - Part 3
 
07:21
In this third video in the series, Steven switches gears to talk about to properly handle exceptions: build or find a single reusable logging procedure and call that. Only pass it variables from your current application state that cannot be obtained via built-in calls, like DBMS_UTILITY.FORMAT_ERROR_BACKTRACE.

Using Oracle's Data Management Workbench (DMW) with InForm and Other Sources
 
59:21
Learn how Oracle Health Sciences Data Management Workbench (DMW) can be used to optimize the management of clinical data from InForm and other sources. -- Data Management Workbench (DMW), an application that was recently introduced as part of Oracle's life sciences data warehousing suite, is designed to combine data from various clinical data sources, such as InForm, and transform it into standard data models. In addition to the many features DMW offers, the solution enables you to run cross-data source edit checks and perform data reviews. Please join BioPharm's Mike Grossman, vice president of clinical data warehousing and analytics, for this complimentary 60-minute webinar in which he will demonstrate how DMW loads, transforms, and cleans trial data from InForm 6.0 and a central lab. He will also show how to use the data for downstream reporting and analysis. To view this webinar in its entirety, please visit: https://cc.readytalk.com/r/xzgb9ola6ji1&eom.
