I am using the ApplicationEventHandler to bind the ContentService Saved method to some custom logic that saves a custom property editor's data into a custom database table. Everything is working fine in the custom table side. But I wonder if it is possible to ignore the normal process and not save the data into the cmsPropertyData table.

This is my code:

using Newtonsoft.Json;
using System.Linq;
using Tigerbay.Cms.Umbraco.CV.Core.Controllers;
using Tigerbay.Cms.Umbraco.CV.Core.Models;
using Umbraco.Core;
using Umbraco.Core.Events;
using Umbraco.Core.Models;
using Umbraco.Core.Publishing;
using Umbraco.Core.Services;

namespace Tigerbay.Cms.Umbraco.CV.Core.Services
{
    /// <summary>
    /// Hooks up all the necessary events into the current assembly / logic
    /// </summary>
    public class HookupEventsService : ApplicationEventHandler
    {
        protected override void ApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
        {
            //hockup events to allow saving and deleting villa information
            ContentService.EmptyingRecycleBin += ContentService_EmptyingRecycleBin;
            ContentService.Deleted += ContentService_Deleted;
            ContentService.Saved += ContentService_Saved;
        }

        private void ContentService_Deleted(IContentService sender, DeleteEventArgs<IContent> e)
        {
            foreach (var deleted in e.DeletedEntities)
                SaveOrDeleteNode(deleted, Process.Delete);
        }

        private void ContentService_EmptyingRecycleBin(IContentService sender, RecycleBinEventArgs e)
        {
            foreach (var id in e.Ids)
            {
                var deleted = sender.GetById(id);
                SaveOrDeleteNode(deleted, Process.Delete);
            }
        }

        private void ContentService_Saved(IContentService sender, SaveEventArgs<IContent> e)
        {
            foreach (var node in e.SavedEntities)
                SaveOrDeleteNode(node, Process.Save);
            // can I ignore the normal saving process,
            // maybe with the ContentService_Saving method
            //(but I need the NodeID, that is why the logic is currently in the Saved method)
        }


        private void SaveOrDeleteNode(IContent node, Process process)
        {
            if (node.ContentType.Alias == "tigerbayVilla")
            {
                var villaNode = node.Properties.SingleOrDefault(x => x.Alias == "tigerbayVillaDetails");
                if (villaNode.Value != null)
                {
                    using (var srv = new VillasSurfaceController())
                    {
                        var json = villaNode.Value.ToString();
                        Villas villa = JsonConvert.DeserializeObject<Villas>(json);
                        if (villa.NodeId == 0) villa.NodeId = node.Id;
                        switch (process)
                        {
                            case Process.Save:
                                srv.SaveVilla(villa);
                                break;
                            case Process.Delete:
                                srv.DeleteVilla(villa.NodeId);
                                break;
                        }
                    }
                }
            }
        }

        protected internal enum Process
        {
            Save,
            Delete
        }
    }
}

I want to avoid cluttering the Umbraco cmsPropertyData table with stuff that will never be used.
