Description
The code is a LaTeX TikZ picture that illustrates the architecture of an online banking system. The picture consists of two rectangular boxes representing two different software applications, an online banking software, and a bank teller software. The picture also includes several other components, such as a user profile app, a user surface, an authentication subsystem, and two apps. The different components are represented by different shapes, colors, and styles, and they are connected with arrows and lines that indicate the flow of data and operations between them.
The code defines different styles for the various components using the TikZ library, such as "purpleBox," "redBox," "orangeBox," "greenCircle," and "lineCustom," each with different characteristics such as fill color, minimum width, minimum height, text color, and text width. The code then positions these components in the picture using relative positioning with respect to other components. The nodes representing the different components are connected with arrows and lines that represent the flow of data and operations between them. The picture also includes labels that provide information about the different components.
