-The DB
+The Database is just a simple table, with simple columns, 
+the model just check both arguments and returns all the data, 
+
+## Compatibility
+
+The DB is designed using mysqlworkbench but the generated sql file 
+must have some tuneup to be compatible with all the others DB:
+
+* remove any `COMMENTS ""`
+* remove any `ENGINE=`
+* remove any special comun data like `AUTOINCREMENT`
+
+## Desing
+
+The mysqlworkbench is pretty complete you can use it and generate 
+the database SQL file later, so tuning with previous hints, 
+will make it compatible, just use `; -- COMMENT`.
+
+Then inside mysqlworkbench use comments to describe the dictionary.
