Advanced Properties dialog

The Advanced properties dialog provides options for extracting and generating database schema information.

The Advanced Properties dialog appears when you open a meta- schema (.4db, .4dbx) file and either:
  • Right click on an empty space in the diagram and choose Advanced properties from the contextual menu.
  • Choose Database > Advanced properties.
In addition:
  • The form shown on the Extraction tab displays when you complete the process to extract a meta-schema from a database.
  • The form shown on the Generation tab displays when you complete the process to generate a database script from a meta-schema file.

Specify that conversion errors should be ignored. If this option is unchecked, the extraction will stop as soon as an error occurs (for example, if a table column has an unsupported type.)
