Naming Conventions :-

1. To understand real time naming conventions                                                    

2. To understand and implement functional or field level validation

• In general in real time programming programmer is not supposed to assign the names of the controls rather Project Leader / System Analyst will design the Forms, Reports and the controls to be present in those, what names to be given to the Controls with in the Design Document
• Programmer should use the same Names given in the Design Document
• In general control name can be divided into two parts
