Evolutility Dictionary Database

"EvoDico" is the database containing the definition of your web applications. With it, there is no more XML, the applications descriptions are stored in the database and edited directly with the application itself.

We ported the XML schema to the following database structure:

Technical details:

• Creating one DB table per XML element and one DB column per XML attribute. We have 4 elements in the meta-model: form, data, panel, and field. These become 4 database tables.
• As the relationship between form and data is a 1-to-1, we can normalize the schema by gathering them together in the same table.
• Let's also add a table for the necessary list of value (here field types).
• Let's prefix our tables with "EvoDico_" to indicate what the table set for "Evolutility Dictionary".
• Finally (not showing in the schema), let's add a trigger to automatically delete fields and panels of a form when it gets deleted.
