Хороший шаблон репозитория для asp.net mvc

Я реализовал шаблон репозитория в своем веб-приложении asp.net mvc... Но я хочу знать, хороший ли это шаблон репозитория, или я все же могу его улучшить...

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using TaxiMVC.BusinessObjects;

namespace TaxiMVC.Models
{
    public class ClientRepository
    {
        private TaxiDataContext taxidb = new TaxiDataContext();
        Client cli = new Client();

        //Get all Clients
        public IQueryable<ClientBO> FindAllClients(int userId)
        {
            var client = from c in taxidb.Clients
                         where c.CreatedBy == userId && c.IsDeleted == 0 
                         select new ClientBO()
                         {
                             ClientId = c.ClientId,
                             ClientName= c.ClientName,
                             ClientMobNo= Convert.ToString(c.ClientMobNo),
                             ClientAddress= c.ClientAddress
                         };
            return client;
        }

        //Get Client By Id
        public ClientBO FindClientById(int userId,int clientId)
        {
            return (from c in taxidb.Clients
                    where c.CreatedBy == userId && c.ClientId == clientId && c.IsDeleted == 0
                         select new ClientBO()
                         {
                             ClientId = c.ClientId,
                             ClientName= c.ClientName,
                             ClientMobNo= Convert.ToString(c.ClientMobNo),
                             ClientAddress= c.ClientAddress
                         }).FirstOrDefault();
        }

        //Insert a new client
        public bool ClientInsert(ClientBO clientBO)
        {
            cli.ClientName = clientBO.ClientName;
            cli.ClientMobNo = Convert.ToInt64(clientBO.ClientMobNo);
            cli.ClientAddress = clientBO.ClientAddress;
            cli.CreatedDate = clientBO.CreatedDate;
            cli.IsDeleted = clientBO.IsDeleted;
            cli.CreatedBy = clientBO.CreatedBy;

            if (!taxidb.Clients.Where(c => c.ClientMobNo == cli.ClientMobNo).Any())
            {
                taxidb.Clients.InsertOnSubmit(cli);
                taxidb.SubmitChanges();
                return true;
            }
            else
                return false;
        }

      //Client Update
        public ClientBO updateClient(ClientBO clientBO)
        {
            var table = taxidb.GetTable<Client>();
            var cli = table.SingleOrDefault(c => c.ClientId == clientBO.ClientId && c.CreatedBy==clientBO.CreatedBy);
            cli.ClientName = clientBO.ClientName;
            cli.ClientMobNo = Convert.ToInt64(clientBO.ClientMobNo);
            cli.ClientAddress = clientBO.ClientAddress;
            taxidb.SubmitChanges();
            return clientBO;
        }

        //Delete Clients
        public bool deleteClients(string Ids, int userId)
        {
            var idsToDelete = Ids.Split(',').Select(c => Convert.ToInt32(c));
            var clientsToDelete = taxidb.Clients.Where(c => idsToDelete.Contains(c.ClientId));
            foreach (var client in clientsToDelete)
            {
                client.IsDeleted = Convert.ToByte(1); 
            }
            taxidb.SubmitChanges();
            return true;
        }
     }
}

и мой ClientBo.cs,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace TaxiMVC.BusinessObjects
{
    public class ClientBO
    {
        public int ClientId { get; set; }
        public string ClientName { get; set; }
        public string ClientMobNo { get; set; }
        public string ClientAddress { get; set; }
        public DateTime CreatedDate { get; set; }
        public byte IsDeleted { get; set; }
        public int CreatedBy { get; set; }
    }
}

Я не реализовал IRepository здесь... Должен ли я реализовать его или мой репозиторий все еще можно улучшить... Любое предложение....
