-# Buffer_2.0
-Buffer_2.0 repo to submit your projects to.Repository containing folder-wise code for all submissions to Buffer : A Project Series, conducted between April, 2021 - June, 2020.
+**SUPERMARKET MANAGEMENT SYSTEM**
+
+**OBJECTIVE:**
+
+* We have tried to implement all the main functions that are required to run a supermarket.This includes billing, maintaining stock details, managing information about products,   dealers and employees. 
+* Our project simulates the job of each and every member working in the supermarket. Every employee will get a different access to the application according to his/her role in     the supermarket.
+* It reduces the time and manpower required for management and maintenance of different tasks as the entire system is fully computerized.
+
+**DATA STRUCTURE:**
+
+We used a Singly Linked List to represent the list of products, dealers, customers and employees that are associated with the Supermarket because:
+* They are dynamic in nature.
+* Insertion order is maintained.
+* This is ideal for our application where we have a large data and unknown number of objects so by using it 
+  insertion and deletion operations can be easily implemented.
+
+ **WHAT WE HAVE LEARNT:**
+ 
+ * How to manage databases using MySQL.
+ * How to implement JDBC.
+ * How to implement linked lists using user defined functions.
+ 
+ **WHAT WE CAN ADD FURTHER:**
+ 
+ * We can define function for calculating Profit and Loss.
+ * We can give login credentials to the employees.
+ * We can make a UI by using JAVA Swing. 
+ 
+ **TEAM MEMBERS:**
+ 
+ * Gouri Ghurka (SY IT)
+ * Himanshi Methwani (SY IT)
+ * Ruchita Herlekar (SY IT)
+ * Muskan Singhal (SY IT)
+ 
+ **MENTOR:**
+ 
+ * Bhavana Mache (B.Tech Comp)
