Abstract: Computer implemented methods for processing transactions involving chemical products include receiving at a server computer from a client computer transaction data that includes a product identifier. In response, testing of a sample of the identified product is scheduled and results of the sample testing are stored in a database. The results may be retrieved in response to a subsequent query from the user and sent over a network to the user. In another aspect, characteristics of a chemical product produced according to a particular formulation are determined, the formulation may be modified, and characteristics of a produce produced according to the modified formulation can be determined. A networked computer system that includes a server, a database, and a memory is configured to exchange data with client computers and is coupled to a database that stores stores chemical product data for a number of chemicals materials. The chemical product data can include, e.g., starting point formulations (i.e.

Abstract: A computer-implemented method of visualizing a decorating project includes rendering an image of a building space (e.g., a room) that includes a number of structural objects (such as doors, walls, and furniture). The structural objects may be portrayed in the rendered image with visual characteristics that are determined by decorative materials (such as paint, fabric, or wallpaper) associated with the objects. The decorative material associated with a particular structural object may be determined based on user input selecting an object's decorative material from a group of available decorative materials. The method may also include generating a listing of selected decorative materials (e.g., for use in a subsequent decorating session) and sending the listing to a purchasing system. A computer-implemented decorating system includes a server operatively coupled to a memory, a database, and to a network over which data can be exchanged with client computers.
