A DMD file may also be a data module created by dBASE, an IDE with database management capabilities. It is similar to a dBASE Form (.WFM file) but only stores data objects, including Database, Query, Session, and StoredProc objects. Data modules allow dBASE users to save objects in one container, which is helpful when re-using a set-up in a different context (e.g., re-using a set of tables from a report in a form).
More Information
dBASE is a Windows application with various features for managing databases and building and compiling programs. Some advantages of data modules include:
- Not needing to duplicate data access components in different contexts (e.g., reports, forms, etc.).
- Designing queries once instead of recreating them repeatedly.
- Separating different types of code for organizational and maintenance purposes.
How to open a DMD file
You can open DMD files with dBASE in Windows. For example, you can open a DMD file by selecting .
Opening a DMD file with a text editor
Since DMD files contain plain text, you can also open the files with a text editor, such as Microsoft Notepad (Windows) or Apple TextEdit (Mac). You may need to rename the .dmd file extension to .txt for the text editor to recognize it.
When opened in a text editor, you can modify the source code in the data module. However, it will not appear the same as if you open the file with dBASE. Also, incorrectly editing the file will corrupt the data module.
