3- JAVA SCRIPT JavaScript (JS) is a dynamic computer programming language. It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed. It is also being used in server-side programming,

game development and the creation of desktop and mobile applications. JavaScript is a prototype-based scripting language with dynamic typing and has firstclass functions. 4- PHP PHP is a server-side scripting language designed for web development but also used as a general purpose programming language. PHP is now installed on more than 244 million websites and 2.1 million web servers. PHP: Hypertext Pre-processor. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data. It has also evolved to include a command-line interface capability and can be used in standalone graphical applications. 3.1.2 BACK END The back end is designed using MySQL which is used to design the databases MYSQL MySQL ("My S-Q-L", officially, but also called "My Sequel") is widely used open-source relational database management system (RDBMS). MySQL was owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Oracle Corporation .MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP open source web application software stack (and other 'AMP' stacks). 3.2 System Architecture The Car rental Management System makes use of a Layered Architecture. Architectural designs have to incorporate the concept of independence and separation. This allows any changes taking place to be localized. A layered architecture applies this notion of independence and separation. The systems functionality is organized and divided into separate layers. Each layer depends on the services offered by the immediate layer beneath it. The system was developed incrementally allowing users to access some services provided by the layers as they underwent development. This architecture is also portable and it can be changed easily. This systems architecture is divided into a number of layers including the web browser, user interface, core functionality, and the operating system/database. (a) Operating System , Servers and Database Layer

This layer comprises of the database and operating system which basically acts as the support software for the system. This system can run on any operating system including Window, Linux, and Mac OS. It makes use of MySQL database running on Wamp Server. PHP server side scripting language was used to code the system. (b) Core functionality Layer This layer houses: The application layer which has all the application functionality.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
