1.1 Project DescriptionIn today’s modern production, water refilling establishments’ daily sales and inventory on the odd

occasion seen to become accustomed the modern world of technology. Small and Medium Enterprises were now

so needy and dependable towards technologies. In order to help some Water Refilling establishments and help

them out on their manual process of transactions and inventory, we proposed a system which will not just

eliminate hassle but an essential system for them for the success and productivity of their business with the help

of technology.

We, Bachelor of Science in Information and Communications Technology 4 th year students in cooperation

with Meribah Water Refilling Station as our main company partner in making this system. We have decided to

make a system which is Water Refilling System that can be very useful for them providing all the necessary

things they want to make their business hassle-free, time saving transactions and more productive.

1.2 Background of the Project

Meribah Water Refilling Station is one of the most valued water refilling establishments in Liloan, Cebu.

They started last December 8, 2004. This station was owned by Mr. Ricardo Anoos and Ms. Annie

AnoosAlponso. They first targeted water dealers as their customers and sold their water by volume and the price

was lesser compared to retailer buyers. They charged for every delivery. If the customer would not return their

bottle, they gave sanctions it was either they will replace it a new bottle or pay for it. For ordering, the customer

will call for them and take its order. Since then, they process every transaction manually recorded, tracked, and

inventory.

They have complete facilities and amenities in the production of their service. They have their own

refilling station beside their house but for now they don’t have any branch. Since they process their transactions

manually, they don’t have computers in their station but the management is very interested of the said system

because they really believe that it could helped them.

The current project is designed to improve the process of transactions of Meribah Water Refilling Station

with the help of technology, this must be implemented. This system is proposed to improve their daily sales,

easier tracking, updating their bottles and customers or for easier inventory.

1.3 Project Objective

In this modern generation, to adapt the changes of technology in answering the company’s needs and

improving the production of services, we aim to develop a system that is unique and will help Meriba Water

Refilling Station make their business safe and convenient.

INTRODUCTION

1.3.1 General Objective

Water Refilling System generally developed for water refilling establishments for them to

conveniently monitor their daily sales and especially their inventory. The system can eliminate inconvenience

on their daily monitoring of their equipments like tracking the bottles and especially their customers.

1.3.2 Specific Objectives

In making this system possible, this will exist as a great solution to the company:

Create a unique system that will easily monitor water refilling establishments’ daily sales and

inventory

Design a system that is user-friendly, realistic and helpful, upgrade faster to water refilling

establishments

Evaluate that the system answers all the users concerns and must be finished on the date required

Test that the system is reachable and helpful to the users

Implement that all the objectives to this project/system really works and surely reduce the users’

tasks.

1.4 Scope and Limitations of the Project

The study will determine the various challenges of the Meriba Water Refilling Station. The

implementation of the system that directed by these challenges will be tested and analyzed. Challenges and

problems of the water refilling establishment particularly on their daily sales, tracking out their equipments and

monitoring or updating their transactions to various customers made easy. However, every study has its own

limitations, since Meriba is a Small and Medium Enterprise, so we focused only on the improvement of its

manual transactions such as tracking of their bottles, records and orders of all customers transactions and the

inventory. The system cannot accommodate the payment of every customer since they should pay their orders

over the counter.

1.5 Significance of the Project/Importance of the Project

This study will be a significant endeavour in promoting good service environment to Meriba Water

Refilling establishment and convenience of its users. This study will also be beneficial to the company and

students in strategic management, corporate strategies and information technology when they employ effective

learning in classroom and workplace setting particularly in different concepts related to the use of web-based

system. By understanding the needs of the users and benefits of quality service, the company and the students will

be assured of a competitive advantage. Moreover, this project will provide recommendations on how to evaluate

the performance of a certain system in accordance to Meribah.

1.6 Review of Related Works and Studies/ Review of Related Literature

The review of related study for this project focuses on inventory, different functions needed and related

studies will be analyzed and reviewed as an essential factor to consider accomplishing this project.

Water Refilling System

An old age says ''if companies had instincts, its first instinct is to survive''. Based on this saying and also

from deeper studies on the water refilling business, we have to develop a software product that enables owners to

detect critical loopholes in its operations that could lead to substantial losses, if not total closure.

Bottle inventory tracking is a major issue in the water refilling business while water systems loss is

another component of potential problems not to mention pilferage and undocumented sales. Our new software

product handles all of these issues.

WATER REFILLING SYSTEM is a result of long interviews to experienced water station owners,

water refillers, delivery boys, and our own experience in the business. It is also a result of or diligent search for

solutions to water station problems.

Functional Features

Some modules that is very essential in having this system. This includes the admin that monitors

everything and everyone. As the users demand this depends on like the list of their transactions,

backgrounds/history, and list of their bottles, daily sales, supplier database, daily inventory, etc.

Ease of Use

A system should have a user friendly functions that even a grade school or a high school graduates can

operate. It is a water station owner friendly software since it was designed to protect the hundreds of thousands

peso investment in the water station equipment, vehicles, chemicals, workers, etc

1.6 Assumptions and Constraints

This describes the assumptions made regarding the development and execution of this system as well as the applicable constraints. Some items to consider when identifying the assumptions and constraints are:

i. Schedule- The system is expected to be complete by the end of February with all the necessary improvements

and additional functionalities to be considered. However, if there are unwanted incidences of delays

such as scheduling of appointments with the company, the schedule will be adjusted. There may be

a lot of revisions to be made for the system. It may not all be considered since there is only limited

time fixed for the system to be developed.

ii. Budget - The system that is being developed has less cost since it will be free of charge for the company. The

initial system installation will be utilizing a free web hosting domain. However, maintenance and

post installation requirements will be counted since there is a necessary procedure for maintaining

the system.

iii. Resource Availability- The system will be launched in Meribah Water Refilling Station as the official Water Refilling System

of the company. However, the company does not have adequate advanced computer equipments

for the future improvements of the system.

iv. Software and other technology to be reused or purchased- The system does not require costly software and other technologies in its launching and installation.

However, if the company wishes to expand and improve their business and production, the system

may need budget for the hosting of the site.

v. Constraints associated with Product Interfaces- The system will be tested and evaluated before its launching. Thus, there will be a room for elimination

of errors and improvement for additional functionalities. However, there are post implementation

procedures to be done which is beyond the developer’s concern. There might be incidences of outdated

standard compliance within the system’s functionalities and processes.

4.1.1 XAMPP

XAMPP is a free and open source cross-platform web server solution stack package, consisting mainly of the Apache HTTP Server, MySQL database, and interpreters for scripts written in thePHP and Perl programming languages.

XAMPP LOGO

Features

XAMPP requires only one zip, tar, 7z, or exe file to be downloaded and run, and little or no configuration of the various components that make up the web server is required. XAMPP is regularly updated to incorporate the latest releases of Apache/MySQL/PHP and Perl. It also comes with a number of other modules including OpenSSL and phpMyAdmin.

Self-contained, multiple instances of XAMPP can exist on a single computer, and any given instance can be copied from one computer to another.

It is offered in both a full, standard version and a smaller version.

IMPLEMENTATION

Use

Officially, XAMPP's designers intended it for use only as a development tool, to allow website designers and programmers to test their work on their own computers without any access to the Internet. To make this as easy as possible, many important security features are disabled by default. In practice, however, XAMPP is sometimes used to actually serve web pages on the World Wide Web. A special tool is provided to password-protect the most important parts of the package.

4.1.2 NOTEPAD++

Notepad++ is a text editor and source code editor for Windows. It aims to be a lightweight and robust editor for a variety of programming and scripting languages.

The Water Refilling System Maintenance Plan has been developed to assure that the Water refilling

System of Meribah Water Refilling Station is adequately inspected and maintained to assure that the system still

meet their design functions. Outlined below are the various inspection and maintenance activities the developers

intend to undertake in regard to achieving these goals:

1. Meribah Water Refilling Station’s Water Refilling System shall be inspected every year to

determine if the system’s technical and software performances are adequate to meet its

design functions. Based on this inspection, errors and possible improvements that are identified for

maintenance will be prioritized.

2. System’s performance will be periodically inspected. During these inspections, unnecessary

functions/modules will be removed and necessary information/modules that to be added so as to provide

reasonable assurances that the system will operate in an unobstructed manner during software or events

errors.
