About DMD files
A .DMD file is most commonly an Oracle SQL Developer Data Modeler project file. Under the hood, these files use a structured XML format to store relational database schemas, entity-relationship diagrams, and structural metadata. Secondary uses for the .DMD extension include Motorola digital mobile data, DEWETRON DEWESoft data acquisition logs, and Dungeon Map Doodler JSON map projects. The primary disadvantage of a .DMD file is its heavy reliance on proprietary, resource-intensive desktop software. Opening an Oracle .DMD file requires installing the full Oracle SQL Developer suite. This locks your database architecture into a specific ecosystem and creates major bottlenecks when sharing schemas with non-technical stakeholders, clients, or frontend developers who do not have the software installed. To make your data models portable and accessible, conversion is necessary. For visual reviews and sharing, convert .DMD to PDF or PNG. For data extraction and version control, convert the internal XML data to raw XML, JSON, or CSV. Drop your file here to view and convert it securely right in your browser.
Convert.Guru analyzes your DMD file, detects the exact format, and lets you read the text inside.
If you want to convert DMD file to PDF, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO or RS, you can use Oracle SQL Developer or similar software from the "Database Schema Design Model" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to DMD, try Oracle SQL Developer or another comparable tool in the "Database Schema Design Model" category.
The DMD Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DMD converter.
