As a company that builds software using Clarion, we often find it helpful to view our Clarion dictionaries (tables / fields) as diagrams. This is especially helpful when taking on an existing project, or when revisiting a project that you haven’t worked on for some time.
There are several tools on the market that offer similar functionality, but they never quite met our expectations. So in 2004 I started building Data Mapper as an in-house tool to assist our own product development.
Then in April 2006 several developers were asking on the Clarion newsgroups about what tool they could use to view graphical representations of their dictionaries. I replied and mentioned that I had built Data Mapper, and the rest (as they say) is history.

So what does it do?

In a nutshell, you open your Clarion Dictionary in the Clarion IDE, and export the Dictionary to a TXD file. You then import that TXD file into Data Mapper.  Or, if you have Clarion 7 installed, then Data Mapper is able to open your Clarion Dictionary (DCT) directly!
You can then use Data Mapper to easily create powerful diagrams, showing your tables, aliased tables, fields, keys, relationships, etc. Then, when you have the diagram looking just right, you can save it as an image file, which you could then email to your colleagues, your friends, your mom, whoever.
Data Mapper can also save your diagram views, print several reports, print diagrams, save diagrams to PDF, and more!
