4GL- Fourth Generation Language

Fourth-Generation Programming Language (4GL) is a computer programming language is  visualised as a refinement of the style of languages classified as Third-Generation Programming Language (3GL).As each of the programming language generations aims to provide a higher level of abstraction of the internal computer hardware details, making the language more programmer-friendly, powerful and versatile.

While the definition of 3GL has changed over time, it can be typified by operating more with large collections of information at once rather than just focusing on bits and bytes. Languages claimed to be 4GL may include support for database management, report generation, mathematical optimization, GUI development, or web development. Some researchers state that 4GLs are a subset of domain-specific languages.The concept of Fourth-Generation Programming Language was developed in late 1970s through the 1990s, overlapping most of the development of 3GLs. While 3GLs like C, C++, C#, Java, and JavaScript remain popular for a wide variety of uses, Fourth-Generation Programming Language as originally defined found narrower uses some of the most advanced 3GLs like Python, Ruby, and Perl combine some of 4GLs abilities within general-purpose of 3GL environment. Also, libraries with 4GL-like features have been developed as add-ons for most popular 3GLs. This make bit difficult to distinguis 4GLs and 3GLs.With respect to type here you can find some examples of Fourth-Generation Programming Language

A Brief Overview On MySQL

A Brief Overview On MySQL

MySQL is an open-source relational database management system (RDBMS)

The name MySQL is a combination of “My”, the name of co-founder Michael Widenius’ daughter Where “SQL”. The abbreviation for Structured Query Language.

The MySQL development projects have its source code available under the terms of the GNU General Public License. As well as under a variety of proprietary agreements SQL was created, owned and sponsored by a single for-profit firm. The Swedish company MySQL AB, which was a software company, founded in 1995. Acquired by Sun Microsystems in 2008. Later in 2010 Sun was acquired by Oracle Corporation.Since 2010 its owned by Oracle Corporation.

SQL is a central component of the LAMP open-source web application software stack and other “AMP” stacks (where LAMP is an acronym for Linux, Apache, MySQL, Perl/PHP/Python). Applications that use the SQL database include: TYPO3, MODx, Joomla, WordPress, phpBB, MyBB, and Drupal. SQL is also used in many high-profile, large-scale websites, including Google, Facebook, Twitter, Flickr, YouTube and by some others too.
