The document reads in a file using a FileInputStream, deserializes it using a serializer, creates an instance of a Porter class, sets a parameter on the porter, executes it on the deserialized model, gets the SQL dialect from the model, generates SQL based on the dialect to drop/insert data, and writes the SQL to a file stream.

50. FileInputStream inputStream = new FileInputStream(inputFile);
JiemamySerializer serializer = SerializerFactory.getSerializer();
RootModel rootModel = serializer.deserialize(inputStream);
Porter porter = (Porter) Class.forName(exporter).newInstance();
porter.setParameter(parameter);
porter.execute(rootModel);

52. FileOutputStream sqlFileOs =
new FileOutputStream(sqlFile);
OutputStreamWriter sqlWriter =
new OutputStreamWriter(sqlFileOs, quot;UTF-8quot;);
Dialect dialect = dbModel.getDialect();
String sql = dialect.createSQL(
dbModel, drop, dml, schemaName);
sqlWriter.write(sql);
