Items, a shopping cart and the conversion of such a cart into an order at checkout in an e-commerce application.
Clips of video and audio, static images etc. and the compiling of these into a single output video for a video editor.
Vertices, triangles, meshes, animation rigs etc. for a 3d editing program.
Accounting standards and tax laws for an accounting system.
