Topic 1:  Temporal Function in DB2 for z/OS, It’s About Time!

DB2 for z/OS Version 10 introduced a groundbreaking innovation that enables the database to manage the time dimensions of

a)      system time (aka audit time, transaction time, or knowledge dates, and in/out dates), and

b)      business time (aka effective date, valid time, or from/to dates)

using SQL extensions that IBM has worked together with ANSI and ISO and all other DBMS vendors to make part of the SQL 2011 standard.  The extensions yield a significant degree of application simplification for applications tracking single and two dimensional histories.  Early adopters have reported:

  • Over 10x reduction in lines of code needed to code this class of applications
  • Appreciable CPU savings when compared with implementing the same functions in the application.

DB2 has also generalized the database enforced unique key constraint to a constraint that enforces uniqueness at each point in time solving a problem that temporal application developers have grappled with for nearly twenty years.  Early users have reported that simply by enabling the new point in time uniqueness constraint, DB2 helped clean problematic data and reduced application errors.

Come hear from the innovator of this technology as he gives a deep dive into this capability while explaining how temporal tables can be architected into your environment, simplify your applications and reporting interfaces, and be managed by your database administrators.  This talk is likely to be of special interest to those who are dealing with audit requirements, insurance, banking, or other financial applications, warehousing applications with the SCD2 issue, retail applications, or government.    

Topic 2:  Row Permissions and Column Masking in DB2 for z/OS Version 10 Delivering Tighter Security for Today’s Applications

Row and column access control is a DB2 data security solution that enables you to manage access to a table at the level of a row, a column, or both.  Implemented through row permissions and column masks, row and column access control is data-centric, policy-driven, and flexible. Unlike multilevel security, row and column access control is integrated into a database system and places the security logic where the data is. It effectively eliminates the need to filter security-sensitive data at the application level and ensures that the data is protected regardless of the applications and tools that are used to access it. All applications and tools that access the database are automatically subject to the same control. 

This session will enable database administrators, database security administrators, application architects, and application programmers to be able to utilize row and column access control and masking to meet the tighter security requirements needed to support today’s applications.
