I recommend my toyorm orm, It very good at dot e.g

type User struct {
     ID int `toyorm:"primary key"`
     Name string
     Age int
     MetaData string 
}
// here Is web response data type
type UserName struct {
     ID int
     Name string

}

you just search data you want

DB,err := toyorm.Open("sqlite3", "xxx")
// error process
var data UserName{}
result,err := DB.Model(&User{}).Find(&data)
// process err & result.Err()

DTO is just an object carrying data for several requests. You just have to make struct and parse the request’s json into that. Afterwards can you iterate over the data and put it in correct structures. If the data sent in the DTO is of very different types it is maybe easiest to parse it as a map of strings to data and iterate over that. https://blog.golang.org/json-and-go
