45
+ < p > PHP, an acronym for Hypertext Preprocessor, is a widely-used open source general-purpose scripting language.
46
+ It is an HTML embedded scripting language and is especially suited for web development. The basic syntax of
47
+ PHP is similar to C, Java, and Perl, and is easy to learn. PHP is used for creating interactive and dynamic
48
+ web pages quickly, but you can do much more with PHP.

+ JavaScript is a cross-platform, object-oriented scripting language developed by Netscape. JavaScript was

+ created by Netscape programmer Brendan Eich. It was first released under the name of LiveScript as part of
55
+ Netscape Navigator 2.0 in September 1995. It was renamed JavaScript on December 4, 1995. As JavaScript works
56
+ on the client side, It is mostly used for client-side web development.

+ In 1986 the Defense Advanced Research Projects Agency (DARPA), the Army Research Office (ARO), the National
68
+ Science Foundation (NSF), and ESL, Inc sponsored Berkeley POSTGRES Project which was led by Michael
69
+ Stonebrakessr. In 1987 the first demo version of the project is released. In June 1989, Version 1 was
70
+ released to some external users. Version 2 and 3 were released in 1990 and 1991. Version 3 had support for
71
+ multiple storage managers, an query executor was improved, rule system was rewritten. After that, POSTGRES
72
+ has been started to be implemented in various research and development projects. For example, in late 1992,
73
+ POSTGRES became the primary data manager for the Sequoia 2000 scientific computing project4. User community
74
+ around the project also has been started increasing; by 1993, it was doubled.

+ The term NoSQL was coined by Carlo Strozzi in the year 1998. He used this term to name his Open Source,
80
+ Light Weight, DataBase which did not have an SQL interface.In the early 2009, when last.fm wanted to
81
+ organize an event on open-source distributed databases, Eric Evans, a Rackspace employee, reused the term to
82
+ refer databases which are non-relational, distributed, and does not conform to atomicity, consistency,
83
+ isolation, durability - four obvious features of traditional relational database systems.</ p >
