CHAPTER FOUR
4.0 SYSTEM IMPLEMENTATION
4.1 INTRODUCTION
This chapter is aimed at describing the tools which was considered to the designing and coding of the system based on the following system requirement. The major requirement which were considered include the database management system, online access, user friendly interface, and data security and fast data transmission. All these requirements, tools and specification properly laid out are transformed into a working system. The system were developed using the following scripting languages. Hypertext markup language (HTML5), JavaScript(JS), Cascading style sheet(CSS), Hypertext preprocessor(PHP), Structure Query Language (MYSQL).
4.2 JUSTIFICATION OF THE DEVELOPMENT TOOLS
These tools adopted for the designing of this system were used because of how well they integrate with each other and proven for the development of similar systems.
4.2.1 Hypertext Markup Language 5(HTML)
HTML is a standard for creating website pages with elements consisting of tags enclosed in single brackets such as <html>, HTML5 is a markup language used for the structure and presentation of world wide web contents and is based on tags that markup text-based documents. HTML5 was developed to solve compatibility problems that affect the current standard HTML4.0 style syntax some include proprietary plugin and APIs (when a web page developed in one browser may not be able to load in another browser). The major advantages of HTML5 is the ability to support multimedia on mobile devices. HTML5 also included some new features which can really change the way users interact with documents including
• New attributes
• Drag and drop capabilities from one HTML5 document to another
• New parsing rules for enhanced flexibility
• Elimination of outmoded or redundant attributes
4.2.2 Cascading Style Sheet
Cascading Style Sheet (CSS) is used to control formatting of element within the layout of website pages and it can be created within a HTML, or within an external style sheet CSS only functions with the existence of an html code. They can be used to define text style color and size. CSS is used or creating styles that can be used repeatedly in a web page which takes less typing than the equivalent formatting with tags, thus saving you kilobytes of disk space (Academic Technology, 2009). Apart from styling which CSS is generally known to be used for the structure of application can be built using CSS, meaning the application would be table less. This attributes increase its demand in today’s web designing (Rose India Technology)
4.2.3 Hypertext Pre-Processor (PHP)
PHP is a scripting language that is widely used by a lot of developers, PHP supports MySQL database and variety of other database such as Sybase, oracle and PostgreSQL, this flexible support is useful if you ever need to move your application to different database (Bacon, 2007). PHP is well optimized to with a fast response time on web applications. This can has a large base of core classes which can be used to build Graphical User Interface (GUI). PHP has the advantage of been scalable and a static language
4.2.4. MySQL (structured Query Language)
This is an open source and a comprehensive relational database server. It have been used to develop web software applications. It supports large database with up to 50 million rows, it is fast and can run on different operating systems. MySQL offers exceptional security features that ensure absolute data protection. In terms of database authentication and mechanism for ensuring only authorized to have access to the database.
