  • pgModeler 0.9.4-alpha is finally ready!
    Multiple layers support, custom canvas colors and much more.

    It took almost half-year to conclude the first alpha release of 0.9.4 due to several problems I was facing. Anyway, I kept working on pgModeler at a slower pace and releasing snapshot buildings until we had reached an acceptable state of maturity for an alpha release. The main improvement of this version is the support for multiple layers as well as custom colors for these entities. Additionally, we have added the ability to change the colors of the canvas elements: grid lines, background color, and page delimiter colors. Functions and procedures can now use custom configuration parameters and transform types. Finally, there were important fixes too, which include the fix to the malformed SQL code related to triggers and functions, several patches in the database importing feature, the correct loading of changelog entries registered in a database model file, and much more. In this post I'll describe some of the improvements in detail, so don't let to read it!

  • Project overview
    Some reasons to use pgModeler

    Easy to use

    Create and edit database models easily with a simple and intuitive interface. The forms indicate which fields must be filled to provide the correct generation of SQL code.

    Open source

    Get, modify, and redistribute the source code without any charge. This project has a public repository that allows forks and full access to the source code. Developers can create their own versions from the existing code.

    Multiplatform

    Built on top of the Qt framework, pgModeler can be compiled on Windows, Linux and macOS. The build scripts are easily configurable to resolve specific dependencies on each operating system.

    Dynamic code generation

    Design once and export to multiple versions. With its dynamic code generation, pgModeler can export the designed models to different versions of PostgreSQL (currently from 9.x to 13.x).

    Plug-ins support

    Missing some functionality? Use the plug-in development interface and create your own extension for pgModeler without change a single line of the core code. See the official plug-ins repository for more details.

    Collaborative development

    Developer or not, you can collaborate! Give your feedback with suggestions for improvements, submit UI translations, report bugs, and much more via pgModeler's page at GitHub.

  • Main features
    Surely pgModeler can be integrated into your development toolset

    Handle several types of objects with an easy interface

    pgModeler supports the creation of the most basic object like a simple column as well as advanced objects like user-defined languages, functions, operators, and many others with easy-to-use forms.

    Automatic generation of columns and constraints

    With the column propagation mechanism, pgModeler automatically creates all columns and constraints as the user links tables using the available relationship objects avoiding repetitive tasks and improving productivity.

    Export models in five different ways

    pgModeler can export the models to a SQL script, to a PNG image, to an SVG file, in the form of a data dictionary in HTML format, or directly to a PostgreSQL server.

    Generate models from existing databases

    With the reverse engineering process, pgModeler can create reliable models based upon existing databases.

    XML based files

    As an open-source tool, pgModeler gives complete access to its source code and the contents of any generated file. All created files are XML based, which means the user can handle them in third party software.

    Restore previous work in case of failure

    In case of unexpected quit, the user doesn't lose all the work because pgModeler stores temporary models with the most recent changes and will restore them in the next startup.

    Model structure validation and automatic fixes

    To avoid breaking references and/or rules during design time and when exporting the model to PostgreSQL, pgModeler validates models from time to time. This validation feature produces an almost error-free database model.

    Customizable features

    With an extensive set of configurations, pgModeler gives the user the freedom to customize most of its features.

    Generate SQL scripts to synchronize both model and database

    Through the diff feature, the user can generate SQL scripts based on the differences between a model and database, or between two databases. The script contains the needed commands to keep synchronized the involved entities.

    Manage existing databases

    pgModeler provides a simplistic yet helpful database management module where it is possible to run SQL commands, explore the objects, and handle data.

    Command-line interface to automate processes

    The CLI offers a good set of operations that do not require the GUI to be running. One of these features is the export process that can be integrated into third party scripts to automate deployment processes. Another useful feature is the model file fix, which consists of repairing a model's structure to make it loadable again (this feature is also available in the GUI). Many other operations are available too.

    Additional features

    Other important features are the object finder for large models, the plugin development interface, support to geospatial data types (as implemented by PostGiS 2.x extension), translatable user interface, and many others.
