How can i pass Data into my SQLite-Database

Hello there :) I am pretty new to programming and I recently started an IONIC App. However I got stuck. I want to do something like a phone book where you can get random JSON contacts and save them to your sqlite database.

I got this:

import { Storage ] from '@ionic/storage';
    @component({
        selector: 'page-home'
        templateUrl: 'home.html'
});

export class HomePage {

  posts: any;
  persons: any;

constructor(public navCtrl: NavController, public http: Http, public storage: Storage) {

  this.http.get('https://jsonplaceholder.typicode.com/users').map(res=> res.json()).subscribe(data => {
  this.posts = data;
 });

}

//here i would like to recieve the data from the tapped Item

  setData(){
    console.log();
        this.storage.set('myData', this.posts);
        console.log(this.posts);
  };


  getData(){
     this.storage.get('myData').then((data) => {
       if (data !=null){
         console.log(data);
       }
    })
  };
}

Here is the View: When i click / tap the save-button i would like to store the values in my sqlite-database and display them in my "local contacts".

<ion-content>
        <ion-list>
            <ion-item *ngFor="let post of posts">
                <ion-list>
                    <ul><h1>{{post.name}}</h1></ul>
                    <ul><p>{{post.username}}, {{post.email}}</p></ul>
                    <ul><p>phone: {{post.phone}}</p></ul>
                    <button ion-button (click)="setData()">Set Data</button>
                </ion-list>
            </ion-item>
        </ion-list>
    </ion-content>

Maybe someone faced similar problems and can help me with this. Thanks :)
