Data entry forms and screens

Abstract

A form is a document that is used to capture data. This chapter discusses several basic form design and screen design principles and identifies some input controls that can be used to screen input data. As the term implies, data capture is the process of initially capturing source data. Data entry, in contrast, is the process of converting the source data into a machine-readable form and entering the data into a computer. In a batch environment, data capture and data entry are sometimes viewed as separate steps. In an on-line or interactive environment, data capture and data entry are combined in a single step. Forms are used to capture source data, and the forms themselves are sometimes retained in long-term storage. Analyze the appropriate data flow diagrams, data dictionary entries, data structures, requirements, and other analysis documentation and identify all the data elements or fields that must appear on the form. A well-designed form can help to enhance data accuracy.
