Design one sample data entry screen for a hotel registration system using the data entry guidelines provided
Question:
Design one sample data entry screen for a hotel registration system using the data entry guidelines provided in this chapter (Table 11-6). Support your design with arguments for each of the design choices you made.
Table 11-6
Transcribed Image Text:
Entry Never require data that are already online or that can be computed; for example, do not enter customer data on an order form if those data can be retrieved from the database, and do not enter extended prices that can be computed from quantity sold and unit prices. Always provide default values when appropriate; for example, assume today's date for a new sales invoice, or use the standard product price unless overridden. Make clear the type of data units requested for entry; for example, indicate quantity in tons, dozens, pounds, etc. Use character replacement when appropriate; for example, allow the user to look up the value in a table or automatically fill in the value once the user enters enough significant characters. Always place a caption adjacent to fields; see Table 11-7 for caption options. Provide formatting examples when appropriate; for example, automatically show standard embedded symbols, decimal points, credit symbol, or dollar sign. Automatically justify data entries; numbers should be right justified and aligned on decimal points, and text should be left justified. Provide context-sensitive help when appropriate; for example, provide a hot key, such as the F1 key, that opens the help system on an entry that is most closely related to where the cursor is on the display.
