CHAPTER-3 FUNCTIONAL AND NON-FUNCTIONAL REQUIREMENTS 3.1Functional Requirements Requirement analysis is a software engineering technique that is composed of the various tasks that determine the needs or conditions that are to be met for a new or altered product, taking into consideration the possible conflicting requirements of the various users. Functional requirements are those requirements that are used to illustrate the internal working nature of the system, the description of the system, and explanation of each subsystem. It consists of what task the system should perform, the processes involved, which data should the system holds and the interfaces with the user. The functional requirements identified are: a. Customer’s registration: The system should allow new users to register online and generate membership card. b. Online reservation of cars: Customers should be able to use the system to make booking and online reservation. 4 c. Automatic update to database once reservation is made or new customer registered: Whenever there’s new reservation or new registration, the system should be able update the database without any additional efforts from the admin. d. Feedbacks to customers: It should provide means for customers to leave feedback. 3.2Non-Functional Requirements It describes aspects of the system that are concerned with how the system provides the functional requirements. They are: a. Security: The subsystem should provide a high level of security and integrity of the data held by the system, only authorized personnel of the company can gain access to the company’s secured page on the system; and only users with valid password and username can login to view user’s page. b. Performance and Response time: The system should have high performance rate when executing user’s input and should be able to provide feedback or response within a short time span usually 50 seconds for highly complicated task and 20 to 25 seconds for less complicated task. c. Error handling: Error should be considerably minimized and an appropriate error message that guides the user to recover from an error should be provided. Validation of user’s input is highly essential. Also the standard time taken to recover from an error should be 15 to 20 seconds. d. Availability: This system should always be available for access at 24 hours, 7 days a week. Also in the occurrence of any major system malfunctioning, the system should be available in 1 to 2 working days, so that the business process is not severely affected. 5 e. Ease of use: Considered the level of knowledge possessed by the users of this system, a simple but quality user interface should be developed to make it easy to understand and required less training.

For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As a general-purpose programming language, PHP code is processed by an interpreter application in command-line mode performing desired operating system operations and producing program output on its standard output channel. It may also function as a graphical application. PHP is available as a processor for most modern web servers and as standalone interpreter on most operating systems and computing platforms. PHP was originally created by Rasmus Lerdorf in 1995 and has been in continuous development ever since. The main implementation of PHP is now produced by the PHP Group and serves as the de facto standard for PHP as there is no formal specification. PHP is free software released under the PHP License. PHP is a general-purpose scripting language that is especially suited to server-side web development where PHP generally runs on a web server. Any PHP code in a requested file is executed by the PHP runtime, usually to create dynamic web page content. It can also be used for command-line scripting and client-side GUI applications. PHP can be deployed on most web servers, many operating systems and platforms, and can be used with many relational database management systems. It is available free of charge, and the PHP Group provides the complete source code for users to build, customize and extend for their own use. 25 Originally designed to create dynamic web pages, PHP now focuses mainly on serverside scripting, and it is similar to other server-side scripting languages that provide dynamic content from a web server to a client, such as Microsoft's Active Server Pages, Sun Microsystems’ Java Server Pages, and mod_perl. PHP has also attracted the development of many frameworks that provide building blocks and a design structure to promote rapid application development (RAD). Some of these include CakePHP, Symfony, CodeIgniter and Zend Framework, offering features similar to other web application frameworks. 9.2 PHP Syntax: HTML and PHP code is written on the same page, and to distinguish PHP code from HTML, the PHP code is enclosed within Tags. For example: php basics


In the above example PHP code is embedded within HTML. In this way PHP and HTML coding is combined on the same page. 26 Since PHP is a server side scripting language, the PHP coding cannot be seen by the end user through view source option, due to this feature PHP is very secure. PHP is a parsed language; therefore PHP environment is necessary at the server for running PHP scripts. 9.3 Working of PHP: Figure 9.1 Working of PHP When a client requests web page containing PHP code from the server, then the requested PHP pages are parsed under PHP environment and interaction with database is made if required. 27 After server side processing, the resulting HTML pages are passed to client and displayed on the browser. In this way the working of php is complete. 9.4 Connecting PHP Application to MySQL Database 1) Make a connection variable to the database: $con= mysql_connect ("localhost","servername","password"); Here $con is a connection variable to database. 2) Select a database over that connection variable: $db=mysql_select_db("databasename",$con); 3) Prepare a sql query to execute: $qry= Select * from abc; 4) Run the sql query: $result=mysql_query($qry); 5) Iterate over the result: while($row = mysql_fetch_array($result)) { //some logic } 28 9.5 Introduction to MySQL: MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to a number of databases. MySQL is officially pronounced ("My S-Q-L"), but is often pronounced ("My Sequel"). It is named for original developer Michael Widenius's daughter My. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements. MySQL is owned and sponsored by a single for-profit firm, the Swedish company MySQL AB, now owned by Sun Microsystems, a subsidiary of Oracle Corporation. MySQL code uses C and C++. The SQL parser uses yacc and a home-brewed lexer, MySQL works on many different system platforms, including AIX, BSDi, FreeBSD, HPUX, i5/OS, Linux, Mac OS X, NetBSD, Novell NetWare, OpenBSD, OpenSolaris, eComStation, OS/2 Warp, QNX, IRIX, Solaris, Symbian, SunOS, SCO OpenServer, SCO UnixWare, Sanos, Tru64 and Microsoft Windows. A port of MySQL to OpenVMS also exists. All major programming languages with language-specific APIs include Libraries for accessing MySQL database. In addition, an ODBC interface called MyODBC allows additional programming languages that support the ODBC interface to communicate with a MySQL database, such as ASP or ColdFusion. The HTSQL - URL based query method also ships with MySQL adapter allowing direct interaction with MySQL database from any web client via structured URLs. The MySQL server and official libraries are mostly implemented in ANSI C/ANSI C++. 29 9.6 Introduction to APACHE SERVER: In this project apache server is used to parse and execute PHP pages, before deploying websites on the server, the website should be tested at the developer side to get a feel of how the website will work on actual server. Therefore apache server is like a local server on the developer side, apache server should be informed about the environment on which it should work. In our project apache server is configured to work with PHP, in this way all the PHP pages are parsed and executed by the server. When apache is installed on the system, then its services is controlled by apache service monitor. Figure 9.2 APACHE Service Monitor 30 CHAPTER-10 SNAPSHOTS SNAPSHOT 1 : HOMEPAGE 31 SNAPSHOT 2: CAR CATALOGUE 32 SNAPSHOT 3: CAR DETAILS 33 SNAPSHOT 4: CAR BOOKING 34 SNAPSHOT 5: BOOKING DETAILS 35 SNAPSHOT 6: PAYMENT PAGE. 36 SNAPSHOT 7: ABOUT US 37 CHAPTER-11 CONCLUSION Car rental business has emerged with a new goodies compared to the past experience where every activity concerning car rental business is limited to a physical location only. Even though the physical location has not been totally eradicated; the nature of functions and how these functions are achieved has been reshaped by the power of internet. Nowadays, customers can reserve cars online, rent car online, and have the car brought to their door step once the customer is a registered member or go to the office to pick the car. The web based car rental system has offered an advantage to both customers as well as Car Rental Company to efficiently and effectively manage the business and satisfies customers’ need at the click of a button. 38 BIBLIOGRAPHY AND REFERENCES Books Used: • • • • Software Engineering - R.S.
