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.

Graphic pattern "Rectangle"-Графический паттерн "Прямоугольник"


 Rectangle




The rectangle shape (range, corridor, consolidation) on the chart is formed from horizontal support and resistance lines. The quote falls into the range after strong price impulses. The longer the price is in the range, the higher the probability of breaking the border.


The universal "Rectangle" pattern can portend both a reversal and a continuation of the current trend. It looks like a side corridor in which the price chart is consolidating, limited by horizontal support and resistance levels. It is recommended to trade in the direction of breaking through the pattern - if the price closes above the resistance level - buy, if the price closes below the support level - sell. The purpose of working out is the height of the pattern (H) in points.
