What I mean is that by having a full form-based user interface, you can prevent the enduser getting access to the database window where they could get into the database structure itself and cause damage - they could delete tables, queries, forms, macros, modules, relationships and reports , they could edit them with hazardous consequences such as changing data types in tables.
All in all, forms are great for creating a user interface and excellent for displaying information rather than just looking at a table and filling in line after line.
