Database Designer for MySQL, developed by MicroOLAP, is a CASE tool for designing MySQL database structures visually. It provides a graphical interface for creating and organizing database diagrams.
An mdd file contains a saved database diagram, including the modeled database structure and its visual layout. It is the native document format used to save the work created in Database Designer for MySQL.
Database Designer for MySQL is a Microsoft Windows application. The mdd format is a proprietary document format associated with that software rather than a general database interchange format.
Open an mdd file with Database Designer for MySQL on Microsoft Windows. Use the application's Open command and select the file.
Database Designer for MySQL can export the modeled database structure as an SQL script, which can be used to recreate the database structure in a MySQL environment.

LightWave 3D Motion Designer is part of LightWave 3D, a 3D graphics and animation application from NewTek. It is used to create vertex-based deformations and animations.
An mdd file stores the animation data produced by Motion Designer. The data describes how an object's vertices move over time and can be used with the corresponding object and scene in LightWave 3D.
The format is associated with the Microsoft Windows version of LightWave 3D. It is a specialised animation-cache format rather than a general-purpose 3D scene or model format.
Open the mdd file in LightWave 3D Motion Designer or load it through the appropriate Motion Designer function in LightWave 3D on Microsoft Windows. The related animated object and scene may also be required for the animation to display correctly.
LightWave 3D Motion Designer can export mdd files to other formats. Open the file in Motion Designer and use LightWave 3D's animation or scene export tools to create output in another supported format.

The mdd file extension belongs to MDict, a multilingual dictionary program available for Microsoft Windows, Apple iOS, Windows Phone, Windows Mobile and Windows CE.
An mdd file stores the multimedia and other resource data associated with an MDict dictionary. The dictionary's main data is stored separately, and the dictionary can refer to resources in the MDD file.
MDD is a companion format specific to the MDict dictionary system rather than a general-purpose resource archive. It remains useful when an MDict dictionary includes embedded or linked media.
Open the related dictionary file in MDict on a Windows Mobile or Windows CE device. Keep the mdd file in the location expected by the dictionary, usually alongside its associated dictionary file, so MDict can find the resources.
An MDD file is not generally intended to be opened as a standalone document.
An mdd file normally cannot be converted meaningfully on its own because it is a resource file for an MDict dictionary. To create a dictionary in another format, the dictionary and its associated resources must be exported or rebuilt with software that supports the source and target formats.

The mdd file extension is associated with Notation Composer, music notation software for Microsoft Windows and other platforms. Notation Composer can transform MIDI music into sheet music.
An mdd file contains a MIDI device description. It is a supporting data file for Notation Composer rather than a MIDI music file or a sheet-music document.
Open an mdd file with Notation Composer on a supported platform. The software may use the file as part of its MIDI device configuration rather than opening it as a standalone document.
An mdd file is a MIDI device description, so it does not have a meaningful conversion to an audio, MIDI music, or sheet-music format. Use Notation Composer to manage the device information instead.
