Map Mysql DB and import into Wordpress to match custom post types field

We have a mysql database and we need to map it and import to Wordpress to match custom post types fields. I'm attaching both DB and custom post type Mapping has to be: table "cimitero" entries goes to -> obituary categories table "comune" entries goes to -> Additional info tab table "defunto" has to be mapped to fit the Obituary post type: POST TITLE: "nome" -> Name + "cognome" -> Surname "data_di_morte" -> Date of Death "data_di_nascita" -> Date of Birth "sepoltura" , "settore", "zona", "posizione_tumulazione", "tipo_tumulazione" all goest to -> Posizione tab "fila" -> Posizione tab with prefix "Fila:" We want the ability to re-import that DB everytime we want, so if used WP All Import would be better.
