1. توسعه پایگاه داده سیستم دسترسی مبتنی بر نقش
2. توسعه یک Customized Filter Attribute بر پایه Authorize Attribute
3. توسعه سرویس‌های مورد استفاده در Authorize Attribute
4. توسعه کنترلر Permissions: تمامی APIهایی که در جهت همگام سازی دسترسی‌ها بین کلاینت و سرور را بر عهده دارند در این کنترلر توسعه داده میشود.
5. توسعه سرویس مدیریت دسترسی در کلاینت توسط AngularJS
