Luna Modeler is a data modeling tool for relational databases – SQL Server, PostgreSQL, MariaDB, MySQL and SQLite.
Several tools can be used to visualize existing GraphQL schemas. Some of them allow you to browse the structure in the form of a hierarchical tree. Galaxy Modeler, on the other hand, offers the ability to visually model new GraphQL schemas and also automatically create diagrams from existing sources.
Before we show how to make a diagram of your GraphQL schema, let’s take a look at how to easily create a brand new GraphQL schema diagram.… Read the rest
In this section we will look at the ability to import a GraphQL schema from a file.
In the demonstration we will use the StarWars schema. If you want to try the procedure, save the file from the page: https://github.com/graphql/swapi-graphql/blob/master/schema.graphql
To load an existing GraphQL schema, go to the Projects section and click the Import file button.… Read the rest

When you create a new index for MongoDB collection in Moon Modeler, the Index Assistant window will appear.
Indexes can be defined easily. Just select the fields, either from the drop down element:
or by typing the field name directly. The auto-completion feature is available for you.
Click the Add button to insert the field to the index.… Read the rest
Settings for graphics can be defined on three levels in Moon Modeler. On a project level, diagram level and on a selected object level.
If you wish to change the footer color (e.g. for easier recognition of the project you currently work with), click the ER diagram area to make sure no object is selected.… Read the rest
Data modeling is the process of visually creating a graphical representation of a system or database. In the case of relational databases, we can mention the creation of entity-relational diagrams in which entities, attributes and relationships between entities are displayed. (Read more information about ER diagrams).
But what is the advantage of data modeling when we talk about noSQL databases?… Read the rest
When it comes to forward engineering in Moon Modeler, it’s about generating the resulting script for the selected target platform.
In the case of relational databases such as PostgreSQL, MariaDB, MySQL or SQLite, it is the resulting SQL script. For MongoDB it is possible to generate a schema validation script and for platforms like Mongoose or GraphQL it is schema definition scripts.… Read the rest
You can save your database structures and schema designs into projects.
On the project overview page, you can search projects by name or platform, quickly find the platform for which the project was created, and also view examples on a separate tab.
To generate a script from your project click the Script icon on the main toolbar. The preview of the script appears in a modal form. Click Save Scripts and select a location where the files should be stored. Option Overwrite existing files allows you to ignore existing scripts and overwrite them without getting a warning.… Read the rest
