Assignment on Data Source Architectural Patterns and AspectJ

we need to design a new variant of an existing pattern. More specifically, you will need to migrate the Active Record data source architectural pattern to an aspect-oriented design using AspectJ, with the goal to decouple the core functionality of a class from any persistence implementation. For simplicity, let us save data into a CSV file. Your application should allow (a) an object to be initialized from data in persistent memory, and (b) persistent memory to be updated once an object state is modified.
What to submit:
1. Create a very small application and package it as a zip file.
