这是存储简单社交媒体统计数据的正确方法吗？

Question

我试图跟踪一些公司真正简单的社交媒体统计数据。在这个阶段，我主要在不同的社交媒体平台上存储他们的总观众规模。

这种结构是最好的方法吗？还是更有效/更好的方式？

存储基础品牌信息

    public class GenericValidationAttribute: ValidationAttribute
    {
        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            var obj = validationContext.ObjectInstance as IBaseObject;
            if(obj == null) return ValidationResult.Success;
            if(obj.content < 0)
               return new ValidationResult("Content have to be greater than zero!");
             return ValidationResult.Success;
        }
   }

    public class SpecificValidationAttribute: GenericValidationAttribute
    {
        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            var res = base.IsValid(value, validationContext);
            if(res != ValidationResult.Success) return res;

            // Do some specific validation
            // ---- 
            return ValidationResult.Success;
        }
    }

存储有关社交网络上特定帐户实例的信息

Schema::create('brands', function(Blueprint $table) {
            $table->increments('id');
            $table->string('name')->unique();
            $table->string('slug')->nullable();
            $table->string('url')->unique();
            $table->integer('total_audience')->unsigned();
            $table->timestamps();
            $table->softDeletes();
        });

存储特定社交媒体帐户的各个数据点。

Schema::create('brandAccounts', function(Blueprint $table) {
            $table->increments('id');
            $table->integer('brand_id')->unsigned();
            $table->foreign('brand_id')->references('id')->on('brands');
            $table->enum('network', array('facebook', 'twitter', 'instagram','youtube'));
            $table->string('network_id');
            $table->timestamps();
            $table->softDeletes();
        });

我应该把索引放在外键上。
