As an alternative to passing a complete array of data to the view helper function, you may use the with method to add individual pieces of data to the view. The with method returns an instance of the view object so that you can continue chaining methods before returning the view:. Occasionally, you may need to share data with all views that are rendered by your application.
You may do so using the View facade's share method. Typically, you should place calls to the share method within a service provider's boot method.
View composers are callbacks or class methods that are called when a view is rendered. If you have data that you want to be bound to a view each time that view is rendered, a view composer can help you organize that logic into a single location.
View composers may prove particularly useful if the same view is returned by multiple routes or controllers within your application and always needs a particular piece of data.
Typically, view composers will be registered within one of your application's service providers. We'll use the View facade's composer method to register the view composer. Laravel does not include a default directory for class based view composers, so you are free to organize them however you wish. Let's take a look at an example of the composer class:. As you can see, all view composers are resolved via the service container , so you may type-hint any dependencies you need within a composer's constructor.
Besides the standard role of basic user-defined views, SQL Server provides the following types of views that serve special purposes in a database. Indexed Views An indexed view is a view that has been materialized. This means the view definition has been computed and the resulting data stored just like a table. You index a view by creating a unique clustered index on it.
Indexed views can dramatically improve the performance of some types of queries. Indexed views work best for queries that aggregate many rows. They are not well-suited for underlying data sets that are frequently updated. Partitioned Views A partitioned view joins horizontally partitioned data from a set of member tables across one or more servers. This makes the data appear as if from one table. A view that joins member tables on the same instance of SQL Server is a local partitioned view.
System Views System views expose catalog metadata. You can use system views to return information about the instance of SQL Server or the objects defined in the instance.
For example, you can query the sys. My bad, I should have checked BOL before writing from memory. I've edited the above accordingly.

DB engines can store 'materialized' views, but that's a different topic.
I know of that but when a view is created some metadata pertaining to the view should be created right? I want to know where that metadata is saved? Any Ideas? In the same database the views are in. In the table specified in my answer. It's stored as permanently as anything in your database is, which is to say you can exlicitly delete it if you want.
