What does a repository look like when using many 1:Many or Many:Many tables?
namespace MVCAzureStore.Services.Caching
{
    public class CachedProductsRepository : CachedDataSource, IProductRepository
    {
        private readonly IProductRepository repository;

        public CachedProductsRepository(IProductRepository repository, ObjectCache cacheProvider) :
            base(cacheProvider, "Products")
        {
            this.repository = repository;
        }

        public List<string> GetProducts()
        {
            return RetrieveCachedData(
                "allproducts",  () => this.repository.GetProducts(),
                new CacheItemPolicy { AbsoluteExpiration = DateTime.UtcNow.AddMinutes(1) });
        }
    }
}
