Table Maintenance

Easily create and edit tables using Surveyor/400

You can create, alter and drop tables and their related indexes and constraints easily using graphical wizards within Surveyor/400. In most cases, adding a field or expanding a field through Surveyor/400 runs much faster than traditional methods, since indexes often do not have to be rebuilt.
