designER runs entirely in the browser and saves the current project automatically, restoring it when the page is reopened. This copy exists only in that browser: to keep a backup, move to another computer or share the project, save it as a .er file.
Name, save and open
- Type the project name in the field at the top left of the navigation bar.
- Save in the toolbox (or Ctrl + S) downloads a
.erfile with the model, its current phase and the notes. - Open project (or Ctrl + O) loads a
.erfile. - New project asks whether to save the current project before opening an empty one.
Saved files take the project name followed by a suffix that shows the phase:
| Suffix | Saved from |
|---|---|
_c | Conceptual model (design phase) |
_r | Restructuring phase |
_t | Translation and logical schema phases |
Notes
Every canvas has a Notes panel on the right. Use it to record the requirements, the restructuring and translation strategies, decisions, and any other remarks. Notes are saved in the project file and can be exported as HTML.
