Developing
The topics in the Developing section describe tasks performed by an application developer.
Presentation layer
WebSphere Commerce uses Java Server Pages (JSP) to implement the view layer of the Model-View-Controller (MVC) design pattern. The view layer is in charge of retrieving data from the database through the use of data beans and formatting it to meet the display requirements. The view layers determines whether the request is sent to a browser or streamed out as XML. JSP files present a clean separation between data content and presentation.
Customizing WebSphere Commerce Accelerator, Organization Administration Console, or Administration Console
The WebSphere Commerce browser-based tools (WebSphere Commerce Accelerator, Organization Administration Console, Administration Console) can be extended or changed. In addition to customizing the tools you can also create a new browser-based tool that uses the same underlying framework. A new tool based on the tools framework is referred to as a WebSphere Commerce tools user interface center.
Tools framework
The tools framework defines user interface elements and functionality used to control and manipulate these elements.
Slosh buckets
The slosh bucket is a common visual metaphor containing two single column lists, side by side. Four buttons are place between the columns: Add, Add All, Remove, Remove All. This control is generally used to pick a subset of unique entries from a larger set of data.

Two examples are:

Choosing which customer segments a suggestive sell is displayed to
Choosing which customer groups a discount applies to
