However, given the characteristics and design of the
starting database, it was impossible to apply this
migration process. Since FileMaker is not really a
RDBMS, a database created from this software does not
comply with the relational model. Therefore, its
information does not represent a set of records and
relationships among them. Besides, data do not have
referential integrity either. Because of all this, it was
necessary to perform a complete design for MySQL,
almost starting from scratch.
