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.
Annuity owners pay an insurance company regular premium payments or a one-time lump sum in exchange for steady income payments that can last for the rest of their life or a fixed amount of years. For example, a $100,000 annuity can provide an annuitant with about $630 monthly, or about $7,600 yearly.
