Oracle

 Oracle Database is a database management system from Oracle. This DBMS is also actively used by large companies and costs a lot of money, but in return it provides great functionality and reliability. Therefore, Oracle Database and Microsoft SQL Server are serious competitors to each other. The results of Oracle in the rankings are not so clear, for example, according to PYPL and DB-Engines, Oracle Database ranks first, according to Stack Overflow Oracle is in eighth position, according to surveys of Oracle software companies in fourth place in popularity. If we take into account only a couple of ratings, Oracle can even be put in first place, but if we take into account all the results, then Oracle cannot be put in first place, therefore, in our rating, this DBMS occupies the third line.

Какие бывают фьючерсы?-What are futures?

 




There are several types of futures contracts in different markets. The speculator is advised to choose one or two contracts and specialize only in them in order to gain a deeper understanding of the market in order to make the right trading decisions. Consider the most common futures:


Precious metals. Traders buy and sell Gold and Silver futures. As a rule, investors, when working with these contracts, seek to hedge against high inflation or general financial uncertainty in the world.

Stock indices. These contracts depend on the movements of stock indexes such as Nasdaq or Dow Jones. On these movements, traders who have chosen futures for stock indices are trying to make money.

Currency futures. These are contracts to buy or sell a certain amount of a currency at a pre-agreed price expressed in another currency in the future.

Energy. These futures contracts include oil and natural gas and serve as a benchmark for world oil prices.

Agriculture. Here, trading is carried out in contracts for soybeans, corn and wheat. Weather conditions and seasonality can have a strong influence on them.

Treasury bonds and interest rates. Such futures contracts play the most important role in international financial markets, and the traders who work with them closely follow the actions of the US Federal Reserve.

Livestock. In this category, participants have the opportunity to speculate on the prices of livestock and pork. These prices are strongly influenced by supply and demand.
