Model Project Structure
The Xomega model project consists of the generators organized into folders, framework files, global configuration, and the actual application model files, as described below.
Xomega generators
Xomega generators are grouped under a special Generators node in the Xomega project and are further organized into folders by their layer or type of output, as well as by technology, where applicable, as illustrated below.
You can easily change the default folder structure for the generators to the one that makes more sense for your application, or delete irrelevant generators from the model project if you don't need them.
You can also add new generators or clone and update existing configurations.
Framework and global config
In addition to the generators, the initial model project will include some framework base types with their configurations, including database-specific types, as well as a global model configuration file, as shown below.
Configuration of the base types is also broken down by technology, which is stored in separate files under the TypeConfigs folder.
The global model configuration is defined by default in the global_config.xom file. You can read about the details of the global configuration in the next section.
Application model files
The main elements of the model project will be the model files for your application. Typically, you want to define groups of closely related model elements, such as for a specific domain object, in separate files, and also organize them by application modules, as illustrated below.
If you are building your application from scratch, then you can add new model files using the Add > New Item... command.
If you have an existing database, then you can import your objects from your database by using the Import from Database generator.
By default, the Import from Database generator outputs the model files into a separate folder Import, so that you could review it, and easily delete it if you need to update something and re-run the generator. You can change the output path for the final run of that generator as appropriate.
If your existing database is not supported, you can still leverage the Import from Database generator. You just need to export a DDL script for your DB structure using your database tools, run it against an empty SQL Server or PostgreSQL database, and then import the objects from that database.
For further details on importing the model from a database please check the description of the Import from Database generator, as well as the step-by-step tutorial.
