IBM Data and AI Ideas Portal for Customers

Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

IDAA full support for column masking

Current support for DB2 tables with column masks is minimal. As column masking becomes more prevalent, the ability to access the data in those tables within our BI environment remains the same. Providing full support (i.e. loading all of the data and ensuring only appropriate access to it from queries) is increasing in importance and needs to be on the roadmap.

    Db2 for z/OS APAR PH33061 delivered partial support, not the full support the Aha Idea was opened for.

    Specifically it delivered support for a subset of queries that can be accelerated, i.e. queries that do not return the MASKed columns to the client application (thus, columns referenced in the outer-most SELECT list).

    To my understanding, data should be loaded into IDAA in the unmasked form. After that, proper masking policies should be applied when executing queries in IDAA - perhaps achieved by creating the column masks in the underlying Db2 LUW engine.
