Early in the development of computer hardware it became evident that to optimize these new machines data management software needed to be developed that could quickly and efficiently access and update the huge amounts of data. Structured Query Language (SQL) arose in a university computer lab environment to allow data to be managed according to relationships. A version became a language know as Ingres (source of gre). After losing commercial viability it was refined and combined with SQL creating a new data management language (hence the Post). The oddly named results were PostgreSQL. PostgreSQL rapidly spread as open source code and was adopted by several major companies including Sun Micro Systems, Sony and Yahoo. Linux, operating system adopted PostgreSQL and standards for the language soon followed. To maintain a standard open source language PostgreSQL certification was introduced.
As with other programs and systems PostgreSQL certification is to maintain uniform standards to insure compatibility, portability and to document the credentials of Data Management System (DMS) professionals. PostgreSQL certification is the professional certification that documents professional competency. PostgreSQL certification training is valuable because of the global prominence of PostgreSQL usage by many of the top international companies. PostgreSQL certification credentials provide DMS professionals documentation that assures the professional is prepared to provide PostgreSQL services in the most reliable, accurate, compatible and ethical manner available.
