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.

Earnings on trading platforms

 Earnings on trading platforms

This includes the sale of goods or the same services on online trading platforms that act as an intermediary between the seller and the buyer. For example, you can sell things that you do not use (are in your possession or are preparing for disposal). So, they can be sold very easily, just on the trading floors. Also, some of your own products that you yourself create as a hobby, but do not sell them on a professional level, including information products and some individual rare services, can also act as goods.


There are both large trading platforms, they are known to everyone, and small ones, but they all have their pros and cons.
