Database components in TIDEPaletteButtons

Hello, I am writing because I have the following problem:

The database components do not appear in the TIDEPaletteButtons.

I link the "TIDEEngine" to the "TIDEPaletteButtons"
only shows the components in the categories:
Standard, Additional, Win32 and Dialogs

What should I do to make the database components available? 

you must register it yourself. Scripter doesn't add those to avoid bloating the package with too many dependencies (like db for example). If you open IDEMain.pas and search for RegisterDataAccessTab method, you will see a commented code that register those components.
