The Work with Machine IDs area lets you perform consultation and data entry (insert, edit, and delete) operations on classes. The insertion and edit data entry operations are stored. These operations carry out a series of formal controls on the data element types. When deleting, however, checks are made on referential integrity on the data stores, which depend on the machine identifiers.
To access the Work with Machine IDs window, click (Work with Machine IDs) from the main window.
