Hi,
1> We are designing a java based application for currency conversion where
the currency name and currency decode values are stored in Currency
Table,The foreign exchange rates are stored in Foreign_exchange rates
table.I have to go ahead and implement this,can you please suggest me some
ideas as to how should i go about implementing this.This scenario is in
Trading based real time application where the foreign exchange rates are
changing every now and then,so my question is how will i get the latest
value which will be in sync and calculate the "correct conversion
rate".Please advice..What datastructure should i use for implementing this.
Currency Table
Currency name| Decode
Indian Rupee | INR
Foreign Exchange Rate(Example) table
CurrencyName| F_E_Name| F_E_Value
INR | USD | 46
INR | EUR | 56
INR | GBP | 80 INR | Dinar | 120 ... so on
The above values will be got from a foreign exchange feeder system,how will
i ensure the values are in sync always?Hope my question is understood now.
Can anyone suggest how to implement this in java
2>How should i implement a "Tree Structure" in Java Based application.?How
would i map the entries to the database table?how many tables will i require
for this implementation.?
List records<String> = new ArrayList<String>();
records.add("null");
records.add("Product");
records.add("Category");
records.add("P1");
records.add("P2");
records.add("P3");
records.add("C1");
records.add("C2");
records.add("C3");
so how should i implement a Tree Structure for the above record set.
//P1,P2,P3 belong to Parent {Product}
//C1,C2,C3 belong to Parent {Category}
