Extract text from DM1 files
To convert your DM1 file to another format, you need erwin Data Modeler or other Database software.
To convert other file formats to the "Data Modeling Diagram" file type, you need software like erwin Data Modeler or a similar tool.
A .DM1 file is a proprietary data modeling project created primarily by erwin Data Modeler (formerly by CA Technologies) or IDERA ER/Studio (formerly by Embarcadero). These files contain complex logical and physical database schemas, entity-relationship diagrams (ERD), and metadata definitions used to architect enterprise databases.
The biggest challenge with .DM1 files is the high barrier to entry. They are locked behind expensive, enterprise-grade licensing (often costing thousands of dollars per seat), making it impossible for stakeholders, developers, or project managers to view the diagrams without the specific authoring software. Furthermore, erwin and ER/Studio use the same extension but different internal structures, leading to immediate compatibility errors if you attempt to open an IDERA file in Quest software. They are not compatible with standard image viewers or web browsers.
To share these models effectively, users must convert them. For documentation and review, converting to PDF or HTML reports is standard practice. For implementation, the model is typically converted (forward-engineered) into SQL (DDL scripts) to build the database. For interoperability with other modeling tools, converting to XMI or XML is necessary.
Convert.Guru analyzes your DM1 file, detects the exact format, and lets you read the text inside.
Users also converted DM, ZIP, ERWIN, CDM and ER1 files.
If you want to convert DM1 file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use erwin Data Modeler or similar software from the "Database Schema Modeling" 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 DM1, try erwin Data Modeler or another comparable tool in the "Database Schema Modeling" category.
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 DM1 converter.
