I have modified the retrieval of transaction table for a particular user along
with the types of bank account. Since there was a column name conflict between
the type of transaction and the type of bank account, I decided to rename the
column name of bank account type to "bankAccountType" instead of type. This
change should not influence the current implementations of adding the bank
accounts or operations related to the bank account type, AS LONG AS we follows
the Bank Schema/Contract. In the other words, it would be better to use the
string identifier than the actual value from the bank Schema. Now I am going to
migrate such a modification to our Plutus.
I modified and test the retrieval of transaction table for a particular user.
Now the transaction table would have a column name, "bankAccountType", to
indicate the transaction is from either checking or saving account in the test
bank workspace. Now, I am going to migrate such a modification to our Plutus.
