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.

Mozilla Firefox

 Mozilla Firefox


The Mozilla Firefox browser is on the fourth position, it is quite a bit behind the Opera browser, but still lost. It is also used by about 10% of visitors.


Positive sides

Even if you don't install add-ons, Firefox will still be a safe and fast browser. Firefox is very reliable and will rarely "please" you with errors and crashes. As a rule, all bugs (shortcomings) and errors are eliminated with regular updates.

Thanks to its open source code, many add-ons and plugins are available for Firefox. With the help of these add-ons, you can "assemble" your browser, i.e. customize Firefox for you and your needs.

Negative side

Firefox will be difficult for beginners. Most users use no more than 10 - 50% of the browser's functionality. If you do not use web development tools, if you are not afraid of viruses and do not want anything complicated, then install Chrome. The abundance of plug-ins and add-ons in Firefox makes the inexperienced user get lost. Most beginners therefore do not use add-ons, and some of them are extremely important and necessary (IMHO, without Adblock and NoScript it is generally dangerous to surf the Internet).

And some Windows 7 users also encountered the fact that when watching a video or listening to music online, their computer hung tightly (did not react to anything, like a screenshot). And the problem turned out to be in a strange conflict with Flash. And this problem is still not fixed.
