How to Prepare for PostgreSQL-CE PGCES-02: PostgreSQL CE 8 Silver Exam
Preparation Guide for PostgreSQL-CE PGCES-02: PostgreSQL CE 8 Silver Exam
Introduction
PostgreSQL is an efficient, open source object-relational database framework that employs and expands the SQL language, as well as numerous features for safely storing and scaling the most complex data workloads. PostgreSQL's roots can be traced back to 1986 as part of the POSTGRES project at the University of California, Berkeley, and the main platform has been actively developed for more than 30 years.
PostgreSQL has a solid reputation for its validated design, dependability, data confidentiality, robust feature set, extensibility, and the open source community's commitment to continuously delivering performant and creative solutions. PostgreSQL is compatible with all major operating systems, has been ACID-compliant since 2001, and includes important add-ons such as the common PostGIS geospatial database extender. It's no wonder that many individuals and companies choose PostgreSQL as their open source relational database of preference.
PostgreSQL has a bundle of features designed to assist developers in building apps, administrators in protecting data confidentiality and building fault-tolerant systems, and you in managing the data regardless of how large or tiny the dataset is. PostgreSQL is strongly extensible in addition to being free and open source. You can, for example, describe your own data types, create custom functions, and even compose code in various programming languages without having to recompile your database. PostgreSQL aims to adhere to the SQL format where this does not clash with conventional functionality or contribute to bad design decisions. Many of the SQL standard's features are supported, but with somewhat different syntax or purpose. More conformity is likely to follow in the future. PostgreSQL conforms to at least 170 of the 179 required functionality for SQL:2016 Core conformance as of the September 2020 update of version 13. As of this date, no relational database satisfies this norm in its entirety.
This certification is for:
Administrators
