Linking Section Access to multiple dimensions

by Stephen Redmond | June 2013 | Cookbooks Enterprise Articles

In this article by Stephen Redmond, author of QlikView for Developers Cookbook, we will look at how Section Access security works by linking a user to the data model. When that user logs in, the data is reduced to only show them the data that they are associated with.

If you have been working with QlikView for a while, you may have come across loops in the data model, causing Loosely Coupled associations. That means you might find it counterintuitive to think about connecting a security table to multiple dimensions in a way that might normally cause a loop. However, QlikView will allow it.

More on ODI

by Christophe Dupupet Denis Gray Julien Testut Peter C. Boyd-Bowman | June 2013 | Cookbooks Enterprise Articles Oracle

Here, we are either using metadata differently than would be expected or we are digging a little deeper into concepts that we have already touched on. Truth be told, this is a catch-all article that addresses questions we've often had to answer, including is conceptions on how the product should be used, and little known secrets that we didn't want to leave aside.

To integrate ODI with external tools, we will look into how to invoke an external program that requires a password or other connectivity parameters, and how to connect to an Excel spreadsheet using ODBC. To help with performance, we will look into how to tune a standalone ODI agent and how to impact the data flow by changing the staging area location.

To load large data, we will work on an example of a KM that can load files containing LOBs. And finally, to help with lifecycle management

In this article by Christophe Dupupet,Peter C. Boyd-Bowman,Denis Gray and Julien Testut authors of Oracle Data Integrator 11g Cookbook, we will look into the use of ODI versioning as well as how to use smart export/import.
