Design

Students should be familiar with and comprehend various aspects of design, including file and data structures, input and output formats, and validation processes. This encompasses understanding file structures such as field length, field name, data type, and coding conventions (e.g., M for male, F for female). They should also grasp validation routines like range checks, character checks, length checks, type checks, format checks, presence checks, and check digits. Additionally, students should know about input formats such as data capture forms and output formats including screen layouts and report layouts.
