miniBank admin will sign in to their account first, and can perform various actions:

- Second widget shows total number of users registered in minibank.
- Third widget gives insight about the total amount present in all the accounts of minibank.

- Line and Bar Chart gives insight about the diffrent type transaction(Money Transfer, Withdrawal & Deposit) performed by all the users in last 100 days(it doesn't actually shows the last 100 days from present day but from some fixed day fixed at the time of deployment of this project due to the fact to due less usage of minibank by its user so chart might be flat due to unavalibility of past data)
All the users are classified based on the type of account they are holding, and their details are available to admin in a very convenient manner
These are the tables from database directly visible to the admin from a web interface.
this table is the initial table in the miniBank database, when a new user registers for account in miniBank therir information are stored in this table, as a new entery is made in this table (i.e new user register) following two **Triggers: generateAccountInfo is fired updating userID table with two 4 digit b/w 1234 & 8766 random arbitrary number which aren't present in the table previously as an cust_id and acc_id and cust_type, acc_type from initial user table.

This table contains customer id, and account id generated randomly corrosponding to each entry in initial user table and plays an essential role in generation of unique account number and unique CIN for each user, as new entry occur into this table a trigger: generateUserCIN is fired updating cin in two tables depositor & advance_taker depending upon the customer type. CIN is generated by concatination of cust_id generated earlier and the cust_type taken fron initial user type as choosen by user.

The idea behind the Customer Identification Number(CIN) is to uniquely identify the user among those who deposit money in miniBank and those who take loan from miniBank, since loan feature isn't yet implemented so a user who chose customer type as ADTR his CIN is generated but account number isn't generated.
if the insertion happen into advance_taker table based on user cust_type choice the system doen't perform any further task. but if user cust_type id DPTR i.e Depositor then furthur account generation occurs based on users account_type. Account is generated by concatibntion of cust_type, acc_type, cust_id and acc_id generated in userID table generateAccountNo Trriger is fired updating diffrent account tables based on user account type choice
