Schema menu

The schema of the database is the definition of its structure: the tables it contains, the fields within the tables, sequences, etc. In addition to database structure, schemas contain validation expressions and validation messages.

Use the Schema options to add, update, or delete table, field, index, or sequence definitions. The following table lists the Schema menu options and gives a brief description of each. The sections following the table contain detailed descriptions of these schemas.
