Hello. In this video I will talk about another feature in some other layer, which is view object instance map to view criteria. What executive units since object in the application module, you will have a lot of view object instances. So if you can have only one view object, but actually from this view object, you would create multiple instance map to the same view object. And you would add this inside that application module. By default, this in this sense will take the same query, which from the main view object, unless you map this view object nested to a view crater.

To explain this, let's go to the junior folder and I will show you exactly what is this object view object in essence, like here, if you can see here you have only one view object which is in believe you object But from this view object you can create multiple instance map to the same view object. So, in the data control you can find here for view object instance However, in the model you have only one view object. So, in the application module we call it view object innocence. So you can create multiple view object innocent as you want. As you can see, as you want you can add any number of innocence from the same view object, but by default, this innocence will return the same result, which has a view object may view object query has. So if you select any instance of this, you will find which of your object this view instance is mapped to old map to the same view option.

So by default, once you add the view object instance, it will get the same result which is the main view object query will return if the Select star from In buoys means all these instances will return all in between, unless you map this view object innocent to a specific view criteria to filter that this is what I mean by view object instance. So as I said in the application module we'll have all view object in a sense and you can add many as you can of view object in this sense and you can measure view object person with a view criteria is that case the view object innocent will be always gets the data from the view criteria. So to do this, you can select one of the existing view object and go to View criteria tab and start creating a multiple view criteria as you want.

After you those you do that, of course, each of you criteria will have its own condition to filter their view object like I will define one view criteria which return all in blue, he was salary greetings and dinky. And they will create another We know the review criteria, which will return all inventory from department number 10, and so on, you can get any view criteria as you want. After you've defined all of your criteria, and each of your criteria has its own condition to filter the view object, you will go to the application would you and in the data model, you start shutting the view and you could get multiple view instance and after that, you would select the View instance and in the edit button you can select the View criteria. In that case, this instance will map to a specific view criteria. And if you use this view in this time from data control anywhere in your application will return only the data which get from the view criteria condition.

So this is how you this is a very important feature and we always use this feature at any if application. Next video, I will go and implement this feature. So see you next video.
