It powers the most commonly used database engines like PostgreSQL, SQL Server, SQLite, and Oracle SQL. Simply put, If you want to access databases then yes, you need to know SQL.It is not really difficult to learn SQL. SQL is not a programming language, it’s a query language. The primary objective where SQL was created was to give the possibility to common people to get interesting data from the database. It is also an English-like language so anyone who can use English at a basic level can write SQL queries easily.SQL is one of the most sought-after skills by hiring employers.You can earn good moneyHow much time does it take to learn SQL?SQL is easy but no one can determine the learning time it takes. It totally depends on you. The method we adopted to help you learn SQL quickly starts from the basics and takes you to advanced level within hours. You can follow the same, but remember you can learn nothing without practicing it. Practice is the only way to learn SQL quickly.What’s the difference between SQL and PostgreSQL?SQL is a language. Specifically, the “Structured Query Language”PostgreSQL is one of several database systems, or RDMS (Relational Database Management System). PostgresSQL is one of several RDMS’s, others of which are Oracle, Informix, MySQL, and MSQL.All of these RDMSs use SQL as their language. Each of them has minor variations in the “dialect” of SQL that they use, but it’s all still SQL.Which is better, PostgreSQL or Oracle SQL?Both are excellent products with unique strengths, and the choice is often a matter of personal preference.PostgreSQL offers overall features for traditional database applications, it is open source and offers great support.Oracle Database has decades of experience and high levels of development expertise. It not only provides more transactions per second than PostgreSQL, but also arguably provides higher levels of security. However, many of Oracle’s security features come at an added cost. Oracle is secure and ensures that user data is not tampered with through prompt updates.Both dialects are very popular today, but PostgreSQL has gained market share recently and is trending upwards because (some have claimed) it has features more suited to today’s dynamic development requirements..Who uses these databases?Here are a few examples of companies that use PostgreSQL: Apple, BioPharm, Etsy, IMDB, Macworld, Debian, Fujitsu, Red Hat, Sun Microsystem, Cisco, Skype.Companies that use Oracle SQL: Gartner, Nike, Costco, Airbnb, eBay etc.
