EuroModeler is a market-leading computer aided software engineering (CASE) tool. It can design databases using Entity-Relationship modelling with the ability to automatically generate SQL code for PostgreSQL engine, which is the heart of the EuroDB database platform.

Graphical database modelling using Entity Relationship diagrams which allow for the efficient creation of abstractions needed in the application design phase. This allows to resolve potential issues when breaking changes do not incur high costs. However, EuroModeler with its powerful features can prove to be a valuable tool throughout the entire application lifecycle – from design tomaintenance.

Modelling

The main function of EuroModeler is to create graphical diagrams of the relations between database objects. You can define a vast array of PostgreSQL embedded objects – such as tables, columns, sequences, views, types – in an intuitive way without the need to write SQL code. The modelling process is supported by built-in tools that allow, among others, the user to:

  • Automatically add columns and constraints (foreign keys) when creating relationships between tables
  • Validate the project based on the database
  • Generate SQL code directly from the ER model
  • Look up objects in very large projects
  • Export the database model in four different ways:
    – SQL script files
    – PNG raster graphics files
    – SVG vector graphics files
    – Directly to the database server.

The file format used by EuroModeler is XML-based, which enables the export of created projects to other tools used during the software development process.

EuroModeler is also well suited for introducing incremental changes that are consistent with Agile software development methodologies. All thanks to the tool allowing for the generation of scripts compensating for differences between the state of the database and the model – so called “diff”.

Management

Another advantage of EuroModeler is a set of built-in tools for database management. The convenient interface includes tools such as:

  • SQL console with syntax highlighting
    – Keyword autocompletion
    – Snippets
  • Hierarchical preview of objects in the database
  • Preview of object definitions in DDL
  • Ability to work on many different databases simultaneously.

In combination with other tools of the EuroDB database platform, such as a statistics or log analyzer, DBA can quickly correct problems, for instance missing indexes.

Maintenance

EuroModeler can also be successfully integrated into existing projects due to its ability of importing the structure from existing databases and automatically creating the entity-relationship model. In this way, it is easy to create up-to-date documentation that takes into account any changes that may have already occurred after implementation.
