Masking is a simple, yet powerful feature of the Technology Explorer that can save you time. The DB2 catalog, and administrative tables and views have many columns that include information in short form. For example the letter 'V' instead of the word 'View'. Unless you have these codes memorized, they can be annoying to look up.

Masking replaces the displayed code with text that is easier to read. The underlying data is not modified so that sorting and searching still work.

There are two types of masks:

In this example, we will reuse an existing mask file and create embedded masks.

For the Dependencies page the codes that need to be masked are the table type symbols. The masks used to replace the table type symbols are common throughout the catalog. Since they are already used elsewhere you can simply reuse the existing mask file located here:
