Oracle Express was a multi-dimensional database and application development environment for building OLAP applications. Normal relational databases store data in two-dimensional tables and analytical queries against them can be very slow.
Annuity Period: The length of time between income payments made under an annuity income plan; the time span may be monthly, quarterly, semi-annually, or annually. Arbitrage: The act of buying and selling commodities in two markets at the same time to benefit from price differences between the markets.
The fixed-period, or period-certain, annuity guarantees payments to the annuitant for a predetermined length of time. Some common options are 10, 15 or 20 years. In a fixed-amount annuity, the annuitant elects an amount to be paid each month until death or benefits are exhausted. If the annuitant dies before the defined benefit is paid, some plans provide for the remaining benefits to be paid to a beneficiary.
