1. Projects
Saved projects are displayed on the Projects page. From this window, you can create new projects, open projects from a file or from a URL, import SQLite database structures from files and more. You can also easily search the list of projects.
Tip: Details of the active project are shown in the footer.
2. Connections
A list of all defined database connections is available on the Connections page. Here you can create new connections, duplicate or edit connections, and run reverse engineering to visualize the existing database structure.
3. Panels
The user interface contains two side panels. On the left is the list of objects, on the right, you can edit the properties of the project, diagram or selected object.
4. Settings & Themes
On the Settings page you can change the theme to Dark or Light, set the number of UNDO steps, where to display tabs with diagrams and other options.
5. Display modes
By default, main objects, e.g. tables and columns (PostgreSQL, MariaDB…) with datatypes are displayed, however you can also display sample data or descriptions. To switch the display, click the Display button and select the desired mode.
Metadata – datatypes
Sample data
Descriptions
Display schema/database in diagram
In projects for relational databases where either schema or database can be defined, the schema can be displayed before the object name.
Display estimated sizes
You can also enable displaying of estimated sizes in the entity-relationship-diagram.
Display cardinality captions
It can be useful to view additional information near reference/relationship lines. Whether it is simple information indicating the maximum number of records, or information containing advanced quantification – the minimum number, the most likely number and the maximum number of records. You can also specify just the max number of records and keep the visualization simple.
Enable the Display cardinality captions option to see the captions in your ERD.
6. Line modes
In Luna Modeler it is possible to switch between two modes of line drawing. Simple and Detailed.
Detailed
In Detailed mode, the line is drawn from column to column.
Simple
In Simple mode, the line is drawn from the center of the table to the center of the other table (or another object).
