The professor's stonebreaker started in 1986 as a follow-up project and a post-Ingres project to overcome the problems of the existing database system. PostgreSQL was developed by the PostgreSQL Global Development Group, which is led by a computer science professor named Michael Stonebraker at the University of California, Berkeley. The primary objective of PostgreSQL is to handle a variety of jobs from single technologies to web service or the data warehouse with several parallel users.The PostgreSQL follow the transaction along with the ACID (Atomicity, Consistency, Isolation, and Durability) properties.Its source code is accessible under PostgreSQL license thus, we can use it freely, change and allocate PostgreSQL in any form.In this, we can describe our functional languages, index types and data types, and we can also create a custom plugin to increase the reliability of our needs.PostgreSQL will offer us the facility to add custom functions with the help of various programming languages such as Java, C, and C++, etc.PostgreSQL is also pronounced as Post-gress-Q-L, which is developed by the PostgreSQL Global Development Group (a worldwide team of volunteers), any organization or other private entity does not control it.The PostgreSQL is the existing database for the macOS server.PostgreSQL is cross-platform and runs on various operating systems such as Microsoft Windows, UNIX, FreeBSD, Mac OS X, Solaris, HP-UX, LINUX, and so on.It is written in C programming language.The multi-version concurrency control attribute is known as snapshot isolation in Oracle. ![]() ![]() It is the first DBMS, which perform MVCC feature, even before Oracle.PostgreSQL is initially introduced on 8th July 1996 at the University of California.It is used to store data securely supporting best practices, and allow recovering them when the request is processed. This tutorial will help us to understand all the primary features of PostgreSQL, also provides a knowledge on how to use PostgreSQL. We are also going to provide PostgreSQL interview questions and quizzes to help you better understand the PostgreSQL language. In this tutorial, we are going to learn all the topics of PostgreSQL language, such as create a database, drop a database, select database, select table, update a record, create a table, delete record, drop table, triggers, functions, insert the record, procedures, cursors, etc. ![]() ![]() Our PostgreSQL tutorial provides basic and advanced concepts of PostgreSQL.
