Gain a clear, detailed understanding of Luna Modeler’s interface. This guide will introduce you step by step to each core UI component.
1. Projects
The Projects page displays all your saved projects with data models and ER diagrams. Easily load, open, or import projects. You can also easily search the list of projects. Read details about 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, change themes or use the Explorer for managing versions. 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, set the number of UNDO steps, where to display tabs with diagrams and other options.
5. Display modes & Diagram options
By default, main objects, e.g. tables and columns (PostgreSQL, MariaDB…) with datatypes are displayed, however you can also display descriptions, indexes, schema etc. To change the visualization, click the Display button and select the desired option.
You can also click the diagram area and set the settings in the side panel.
Display descriptions
Descriptions can be displayed below tables. The following screenshot show a visualization with table columns, indexes and descriptions. Column data types are hidden as well as schema name and information about estimated sizes.
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 four line modes.
Detailed
In Detailed mode, the line is drawn from column to column.
Detailed – curved
Detailed – straight
Simple
In Simple mode, the line is drawn from any side of an object to any side of another object. The positions of columns in tables do not matter.
Basic – curved
Basic – straight
In Luna Modeler version 10.1, you can also set a line mode for the selected relationship line.
