Mutual Funds: The system offers a variety of mutual funds of which the basic ones are money market,
real-estate, short-term-bonds, long-term-bonds, balance-bonds-stocks, social-responsibility-bonds-stocks,
general-stocks, aggressive-stocks, and international-markets-stock. Each mutual fund has a name (e.g.
money-market), is identified by its symbol and belongs to one or more categories: fixed, bonds, stocks, and
mixed. For example, money-market and real-estate are fixed. However, balance-bonds-stocks and social-responsibility-bonds-stocks are mixed. The database also maintains a description of each fund. Information
about the date when the fund was created and the total number of shares of this fund is also maintained.
The database keeps track of the closing price of each mutual fund, that is, the price of the mutual fund at
the end of the previous day that is given by a date. This price is used in today’s purchases,
exchanged/traded shares and calculation of investment.
