DB2 for i - Row and Column Access Control (FREE FOR MEMBERS)

 

by Scott Forstie, IBM

Tuesday, February 17, 2015 • 12:00 pm Central Time

 

With IBM i 7.2, Row and Column Access Control (otherwise known as RCAC) was added to DB2 for i.  This new capability creates a compelling alternative to traditional techniques for limiting access to data. 

 

Attend this session for a technical overview of the new capability.  The session will include a comparison of the most frequently used techniques for limiting access for data and will show how RCAC constructs could be used to deploy a data-centric solution. Working examples and IBM i specific details will be included, making this session a valuable investment.  

 

Arm yourself and your staff with the knowledge needed to improve your data security.

Analyzing Recursive Data with SQL (FREE FOR MEMBERS)

 

by Birgitta Hauser, Toolmaker GmbH

Thursday, April 2, 2015 • 12:00 pm Central Time

 

According to the SQL Standard, hierarchical (e.g. organization charts, bill of materials) or bi-directional data (e.g. flight connections) can be evaluated by using a recursive common table expression (RCTE). RCTEs were integrated with release V5R4 into DB2 for  i. Other databases such as Oracle use a non-ANSI SQL Standard method for querying data called hierarchical query clause. To allow maximum portability the hierarchical query clause is introduced with PTF SF99701 Version 9 in DB2 for i. This session will show you both methods in depth.

 

Learning Objectives: In this session you’ll learn how recursive data must be stored in database tables/files and the methods (Recursive Commont Table Expressions and Hierarchical Query Clause) to be used to analyze them.

 

Audience: Developers and Users who are experienced in SQL Queries and need to evaluate recursive data or simply want to enhance their SQL know-how.
