This database demonstrates 3 features in 4D Ajax Framework: data tree, developer defined window (DDW) and image matrix (available in 1.1).

Data tree is used to display the list of cities and contacts who live in the city.

The DDW is used to load the contact information into the iFrame (above the image matrix) when a photo is clicked.

The image matrix loads the contact photos directly from the backend when the a city or contact name is clicked in the data tree. Each photo in the image matrix is set to zoom-in and out when double-clicked.
