Increments

It is not easy to create a new baseline every time the database changes as it causes too much overhead. Hence the schema changes are managed through Delta DF files and Data conversion programs, while the data changes are managed with XML dumps of new, changed, deleted records and X/E Files settings.

All these changes are stored in <DB Baseline dir>/incr/ folder and are identified by a 4 digit Increment Number. The first Increment is 0001, the second 0002, and hence-on.

It is essential that all files must have a unique monotonically increasing number as it defines the order to load. A rule states that after an increment is committed to SVN it should not be changed. When a new Database Baseline is created all previous increments are deleted, and the Increment number is reset.
