Luna Modeler and performance improvements in version 13.5
Check constraints defined in Luna Modeler data modeling tool for SQL databases.

Check Constraints

  • Check constraints are now available in their own section, where you can define check constraints for both tables and individual columns.
  • Check constraints are taken into account during modeling, model updates and when generating creation and synchronization SQL scripts.
  • Supported for physical data models for Oracle, SQL Server, MariaDB, MySQL, and PostgreSQL.

SQL Server Features

  • Support for Filegroups
  • Support for defining and reverse engineering the SET QUOTED_IDENTIFIERS and SET ANSI_NULLS options.
  • Available for modeling, model updates, and generating synchronization SQL scripts.
  • Improved generation of comments for SQL Server objects

Database Specific Features

  • PostgreSQL: support for WHERE clause in indexes
  • MySQL/MariaDB: comparison of indexes in a given order / sorted alphabetically. This affects model update and comparison features

UI/UX Enhancements

  • We’ve improved how Copy/Paste operations work. You now have access to the standard Paste option, as well as Paste with autolayout, Paste here, and Paste here with autolayout via the context menu. This gives you more control over how objects are placed and helps you avoid having to rearrange them manually.
  • Objects added to a sub-diagram will be inserted with their default colors and placed in available space using autolayout.
  • If there are multiple relationships leading to an object, the connectors are spaced further apart, which improves readability.

Application Settings

You can now turn on or off the panels displayed on the left side. This allows you to easily turn off the Themes panel, Explorer panel or hide or show the Assets panel. If you want to add flowchart or data flow diagram elements to your diagram, you can easily turn on the Assets panel and conveniently insert additional objects into your diagrams.

Markdown Notes

In addition to classic texts and notes, you can add Markdown notes to the diagram, which support classic markdown and some HTML elements. This makes it easy to create a table, list, or add an image with a specific size.
