There are some Go database drivers for redis:

The best driver for mongoDB is called `mgo`, and it is possible that it will be included in the standard library in the future.
Install mgo:
```Go
go get gopkg.in/mgo.v2
```
Here is the example:
```Go
package main
import (
"fmt"
"labix.org/v2/mgo"
"labix.org/v2/mgo/bson"
"fmt"
"log"
"gopkg.in/mgo.v2"
"gopkg.in/mgo.v2/bson"
)
type Person struct {
Name string
Phone string
Name string
Phone string
}
func main() {
session, err := mgo.Dial("server1.example.com,server2.example.com")
if err != nil {
panic(err)
}
defer session.Close()
session.SetMode(mgo.Monotonic, true)
c := session.DB("test").C("people")
err = c.Insert(&Person{"Ale", "+55 53 8116 9639"},
&Person{"Cla", "+55 53 8402 8510"})
if err != nil {
panic(err)
}
result := Person{}
err = c.Find(bson.M{"name": "Ale"}).One(&result)
if err != nil {
panic(err)
}
fmt.Println("Phone:", result.Phone)
session, err := mgo.Dial("server1.example.com,server2.example.com")
if err != nil {
panic(err)
}
defer session.Close()
// Optional. Switch the session to a monotonic behavior.
session.SetMode(mgo.Monotonic, true)
c := session.DB("test").C("people")
err = c.Insert(&Person{"Ale", "+55 53 8116 9639"},
&Person{"Cla", "+55 53 8402 8510"})
if err != nil {
log.Fatal(err)
}
result := Person{}
err = c.Find(bson.M{"name": "Ale"}).One(&result)
if err != nil {
log.Fatal(err)
}
fmt.Println("Phone:", result.Phone)
}
```
We can see that there are no big differences when it comes to operating on mgo or beedb databases; they are both based on structs. This is the Go way of doing things.
