What Do I Need?

All of the 4D components available from Deep Sky Technologies, Inc., function in tandem with each other. The functionality that any particular component provides can be dependent upon the functionality of one or more other components and/or plugins. This is particularly true of the Internet related components.

For the Internet related components, TCP Deux is the base, or "lowest", level component which is always required. TCP Deux, along with the utilities within the BASh component and one of the compatible TCP plugins (e.g. Internet Commands v6.7.x, Internet ToolKit v2.0.x, or Internet ToolKit v2.5.x), form what is called the Core Components & Plugins. All other Internet related components work in conjunction with all of the individual parts of this group of development tools.

The group of Client Components provide functionality to 4D developers from a client perspective when making connections online. For instance, HTTP Client Deux provides functionality similar to a web browser in its ability to retrieve remote objects on the web. All of the components in this group work "on top" of the tools in the Core group. This can even be embedded upon one another; for instance, the eTrans component works "on top" of the HTTP Client Deux component within this group.

Some components or groups of components have particular requirements to function properly. These are indicated in the graphic, below, by the green numbers; a legend below the graphic describes the particular requirements of each mark. For secure transactions, obviously, Internet ToolKit v2.5.x is required as it is the only TCP plugin which supports SSL connections.
