Reverse engineering is what we call the process that takes a given database and turns it into a model driven “thing”.

You just need to give a valid connection string to it;

in this case a use the MusicStoreDb from a MicrosoftSample:

You start by Analyzing the database:

And then you “Go!” – be aware of that this process will empty the package you started from and fill it with the stuff from the reverse engineer process:

Giving us this in the modlr tree:

And I will drag these classes out on a diagram to get this:

And that is enough information to run the model against the exact same database as we reversed it from:

Giving us a way to use the trusty AutoForms and EcoSpaceDebugger to look at the changeble data :

In this particular database the RecordId, ArtistId and sofort are of type int in the database and are designed with “Is Identity==true” in SqlExpress. Also the “Identity Increment” is set in SqlExpress.

The Reverse algorithm gave us a model with int Attributes for the ID – we want ECO to be able to use that Key scheme instead of the standard ECO_ID :
