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.

CCI indicator (Commodity Channel Index)

 

Commodity Channel Index (CCI) is translated as "Commodity Channel Index". This non-normalized oscillator was developed by stock trader Donald Lambert, who used CCI to trade the commodity markets. The Commodity Channel Index indicator helps to determine the current state of a financial instrument: overbought or oversold.


The CCI indicator evaluates the current relationship between the price and the simple Moving Average (MA). In other words, the indicator shows the deviation of the instrument's price from its average values. Maximum CCI values ​​indicate that quotes have risen significantly and deviated upward from average prices, while minimum values ​​indicate that quotes have already fallen quite strongly and deviated downward from average prices.
