    <p>DCI is a paradigm and as such there's no angularJS way of doing it, either the language support DCI or it doesn't. JS support DCI rather well if you are willing to use source transformation and with some drawbacks if you are not. Again DCI has no more to do with dependency injection than say a C# class has and is definitely not a service either. So the best way to do DCI with angulusJS is to do DCI the JS way, which is pretty close to how DCI is formulated in the first place. Unless you do source transformation, you will not be able to do it fully since the role methods will be part of the object even outside the context but that's generally the problem with method injection based DCI. If you look at <a href="http://FullOO.info" rel="nofollow noreferrer">fullOO.info</a> the authoritative site for DCI you could have a look at the ruby implementations they also use method injection or you could have a look at <a href="http://runefs.com/category/dci/" rel="nofollow noreferrer">here</a> for more information on DCI. It's mostly with RUby examples but the DCI stuff is agnostic to that. One of the keys to DCI is that what the system does is separated from what the system is. So the data object are pretty dumb but once bound to a role in a context role methods make certain behaviour available. A role is simply an identifier, nothing more, an when accessing an object through that identifier then role methods are available. There's no role object/class. With method injection the scoping of role methods is not exactly as described but close. An example of a context in JS could be</p> <pre><code>function transfer(source,destination){ source.transfer = function(amount){ source.withdraw(amount); source.log("withdrew " + amount); destination.receive(amount); }; destination.receive = function(amount){ destination.deposit(amount); destination.log("deposited " + amount); }; this.transfer = function(amount){ source.transfer(amount); }; } </code></pre>

    1. COThanks for elaborating the DCI stuff. It is a great read. But my questions really aims at "where to put the model objects in angularjs". DCI is just in there for reference, that I might not only have a model, but split it in the DCI way. Will edit the question to make it more clear.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
