\title Important Concepts In Qt Quick - Data - Models, Views, and Data Storage
\brief Overview of the data, model and view concepts
 
Most applications will have data that needs to be displayed to the user.  That
data might come from a variety of sources: network sources, local files, and
databases are all common sources of data.
 
\section1 Models and Views
 
It is often advantageous to show similar data in a similar manner, within an
application, and this gives rise to the idea of having a model which contains
data, and a view which displays the data.  The view will display a delegate
for every datum in the model.
 
For information about how the Model/View paradigm is implemented in Qt Quick,
see the page titled \l{qtquick-modelviewsdata-modelview.html}
{Models and Views in Qt Quick}.
 
\section1 Data Storage and Access
 
Databases are commonly used to store information in applications, and Qt includes
\l{Using SQL databases with Qt Quick Views}{models that provide access to SQL databases}.
For simple access to SQLite storage, Qt Quick provides the \l QtQuick.LocalStorage module.
