the bank calculates the quantity of certain financial product on a client account

Primary LanguageJava

A bank deals with client accounts. An account contains details of various clients’ financial products. These products could be: • stocks, • bonds and • derived products. A derived product is a combined financial product it’s like a “basket” which contains other financial products: stocks, bonds or even other derived products. For example Derived Product “Ruby” contains 10 IBM shares and 4 Hungarian Government Bonds. That also means if you own 2 of this product basically you have 20 IBM shares and 8 Hungarian Government Bonds. All these products have the same properties (like id, name, description, etc.) but derivatives and bonds have an extra property: expiry date.
