After reviewing about JSON and XML from the provided URL or from Oracle (www.oracle.com, then search for JSON and XML), as a typical Model, build a Database (DB) Table including Attributes (Fields) and one or two sample record (sample values for the given attributes). As you know in Table, the records are your Table’s Rows and Attributes are the Columns. In this Model the Attributes (columns) should be for a typical Bank Checking Account like First Name, Last Name, Middle Initial (MI), Account #, Bank Routing Number, Banking Action performed (like Deposit, Withdraw, Checking Balance, and etc.), Home Address, Phone Number, Account Balance and many other field. Just simulate a Bank Checking Account and include Attributes (Columns – Fields ) that you need for that.
