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.

What is CMS


 What is CMS


In today's world, only a small part of sites are created from scratch, i.e. through full-fledged programming, development of functionality, interface and the entire logic of the site, usually this is how large information systems or some specialized services are developed.


Most websites today are built using so-called "content management systems (CMS)", commonly referred to as the "website engine". But what is it?


CMS is an application (a set of scripts) that can be installed on hosting and created with the help of it your own full-fledged personal website and its further maintenance, i.e. fill and edit the content of the site (its content).


At the same time, you will not be programming in the classical sense, i.e. You do not need to know programming languages, you will not write code, you will create a website by installing the necessary extensions (plugins), configuring these extensions, configuring the CMS itself, this whole process reminds me of the process of setting up the operating system (Windows or Linux) for yourself, those. If we draw an analogy, then the operating system acts as a CMS, and the programs that you install into the system act as extensions (plugins).

In other words, websites today are created in exactly the same way as you set up an operating system, install programs into it, and set up these programs without programming at all.


Thus, in the modern world, creating a website is actually quite simple, you just need to know the basic principles of working with CMS.


The whole problem is that there are a lot of such CMS, some are aimed at creating blogs, some are aimed at creating online stores, some are paid, and some are free, the same can be said about extensions, there are extensions paid, and there are also free.


Therefore, in order to create a website, a person needs to select a CMS, configure it, select the necessary extensions, and configure them, as well as check the correctness of their work.
