INTRODUCTION

Computers over the past years have changed the way the people lived. It

provides information in just a short time; it made our life easier, more

comfortable. Having it around, computers also served as a tool for doing work in

a much lesser time with definite accuracy and with lesser effort. Cellular phone is

the technology used for communication. Mobile phones are considered as a

luxury, but as technology progresses, it became a necessity, Philippines is

considered as the one with the highest number of population who adapts text

messaging as a mean of communication. It manifests that most people use to

consider short messaging services rather than using a call.

Being able to cope up with the fast changing technology, many

businessmen want their company to be globally competitive, to enhance the

working capabilities of the employees.

Information Technology keeps the computer alive. People are always

hungry for new things and latest development. In the future a new model will be

introduced, and since its wireless, people can easily adapt to its features. It is

one of the hottest areas in the field of communication and it is predicted that

within the next decade a considerable number of connection will partially or

completely become wireless. Rapid development of the internet with its new

services and applications will create fresh challenges for further development of

1

mobile communication system. In a much larger scale, PDA phones are being

used by millions. Using PDA in monitoring stocks online will grant the user

accessibility, and it will make the business flow smoothly without creating errors.

This chapter discusses the background of the study, statement of the

problem, hypothesis, significance of the study, and its scope and limitations.

Background of the study

Some businesses today are still using the old-fashioned way of monitoring

the stocks of incoming and outgoing items in which it still uses man power for

checking stocks, making inventory reports, and updating product details and

stocks. All of these pieces of information are stored on different record books for

each transaction. On most cases there is an assigned employee who would

actually record the stocks on a file card, and store it in the inventory, wherein all

the file cards are kept.

Every single piece of information is exceptionally important. With manual

record-keeping, data loss and data inaccuracy are somehow known to be a

problem caused by record misplacement and redundancy of records. Adding and

updating stocks information are also complicated since everything is done

manually. Searching of data takes time because the assigned employee have to

check each file card in the inventory, although these file cards are actually sorted

2

8/3/2019 Chap1 to 5

3/53


chronologically, its still understandably slow. Furthermore, given that all of these

sensitive pieces of information are just kept in a filing cabinet, unauthorized

access is a problem. Overall, it is apparent that the existing system is, or at any

rate, inaccurate, inefficient, slow, and vulnerable.

As a resolution to the said problems, the proponents have developed the

Online Stock Monitoring thru PDA which can help to minimize time consumption

in making inventory reports, checking of stocks, and updating of product details

and stocks. The system also prevents loss and redundancy of records. In

addition, the system also has a search function which dramatically improves

searching of records. This search function has a wider capability of searching

records because it supports wildcards. The proposed system has a dedicated

web-based interface which is accessible through any Internet-capable device

such as PDA phones. PDA phones contain features that are more advanced and

technologically inclined. The company owner can now browse the Web-based

interface through his mobile device. This makes the proposed system more

accessible over the existing system. With this technology, being introduced in the

business community creates admission where technology uses its advantages to

promote the economic growth of the business.

Statement of the Problem

The study aims to develop an Online Stock Monitoring thru PDA that

would enhance the current system.

Specifically, this study attempts to answer the following questions:

1. What is the demographic profile of the respondents in terms of:

1.1 Position,

1.2 Computer Literacy, and

1.3 Familiarity on PDA?

2. Is there any significant differences between the proposed system and

the existing system in terms of:

2.1 Accuracy,

2.2 Accessibility,

2.3 Reliability,

2.4 Speed,

2.5 User-friendliness, and

2.6 Security?

Hypothesis

The hypothesis will be formulated and tested at 0.05 level of significant

measurement.

4

8/3/2019 Chap1 to 5

5/53


There is no significant difference on the evaluation made by the

respondents in terms of the following criteria:

1.1 Accuracy,

1.2 Accessibility,

1.3 Reliability,

1.4 Speed,

1.5 User-friendliness, and

1.6 Security.

Significance of the Study

The following groups and individuals will benefit from this study:

Employee. The employees are in-charge of making the inventories;

they can update the product details and its stocks much faster thru

barcode reading.

Owner. The owner can monitor the stocks of inventory thru PDA

but if the PDA fails theres an alternative way of monitoring it

Online.

Future Researchers. This study will help the future researchers to

have an idea and will give them abundant information regarding

how useful PDA phones are.

Scope and Limitations

The proposed system has two separate components. First is the

Windows-based application which is completely focused on the stocks

information and data alteration. Second, the Web-based application which is

accessible through any Internet-capable device including PDA phones that is

limited for viewing or retrieving the stocks information only. Almost everything is

in fact being done using the Windows-based application; this includes adding

new records, modification of existing records, searching of records, and report

generation. Information such as incoming products from the supplier and current

count of deployed products can be manipulated in the heart of the system.

Moving on, the purpose of the Web-based interface is to give a view of the

updates of inventory. A designated employee can have an access through their

phone via the Internet. They can have a full report on the sales and inventory

system of the company without any hustle of checking. All files regarding the

sales and inventory systems are shown chronologically. The time, prices, sales

report and quantities of the products are listed accurately. The proposed system

also has a Report Generation Module that can provide a printable inventory

reports through the Web. The reports are presented in a grid view. The

Maintenance Module gives the user a back-up data that can be featured in a

specific time frame or by the provider. The Inventory Module presents the

monitoring of stocks through online and in its stand-alone application.

According to One of the Staff of Computer World Philippines (2007), The Right

to Privacy,

Keeping customer data private and secure is a challenge that anycompany, regardless of industry, has to address. While varioustechnologies have long been available to protect vital customerdata, companies that currently have or are headed towards havingan Internet-based business component is exposed to an entirelynew set of threats to their data.

According to Francisco, A. (2009), Mobile Phones Continue Evolving

While some electronic toys and gadgets come with some dumpingdown effects on their users, most of these devices offer increasinglevels of convenience.

Take the mobile phone, for example. While too many accidents andmishaps might have been caused by improper (read: stupid) waysof using the cellular phone, it cannot be denied that these wirelesscontraptions have made it easier by far to keep in touch with other

people.

Yet, while todays Smartphones might seem like a giant steptoward the mobile equivalent of Nirvana, the possibilities for moreease and comfort seem endless. We might have only scratched thesurface.

According to Canlas and Gonzales (2004),MIS demystified 2

The proposed system shows how the world depends on technology, how it

reacts in the fast changing development. Computers and PDA phones are being

used worldwide. It gives a company all the benefits to become profitable. It also

makes the company not only national but globally competitive. Thus making

ones company a factor for a nation to become economically stable. The system

helps in lessening the time and efforts to be exerted in making inventory reports,

creating a good and healthy environment.

In the study of PIASECKI, DAVID S. he says that inventory accuracy

starts with an understanding of the conditions. Under which errors occurs and

ends with errors resistance processes. It implies that PDAs technology makes

the workload easier.

Also in the study ofMENDOZA, J. state that inventory management is an

integral part of a successful business. This means that if a company has a well

organized inventory system, there would be a countless chances of progress.

The study completed by Ortega entitled Inventory System of Level-up!

Inc. it help the proponents to the proposed system of having an idea on how to

monitor the incoming and outgoing of items.

Theoretical Framework

Figure No.1Theoretical Framework of the Existing System

The current system uses a Record book in recording items. They have to input

the quantity of the items, name of items, their prices, they do manual counting

and tracking of items, also checking and monitoring of stocks availability

manually. After that the verified items, updated item records, recorded

transaction and the generated reports are being stored in a filing cabinet for

future references.

Figure No.2Theoretical Framework of the Proposed System

In this proposed system, Online Stock Monitoring Thru PDA it lessens the human

effort and made work faster and accurate. The system provides alarm as a

reminder if the items are already out of stock and it can back-up files, the system

can provide reports for the management, and it can provide printable receipt for

the customer. The system can record all the transaction done in the company

including the item description and provide printable reports for the management

whether it is master list, daily transaction, weekly transaction, monthly transaction

and annual transaction.

In the current system, the criteria mentioned were less effective. It makes

the work slower due to the fact that it is being done manually. With this, the

record sometimes been misplaced causing the employees much time and effort

to revise the whole thing. The propose system in line with its accuracy,

accessibility, speed and user-friendliness makes the work faster and more

accurate. And since it serves as a storing device the sales and inventory systems

of the company are bring filed in a clear and orderly manner

MATERIALS AND METHODS

This chapter discusses the methods of research under research design.

There are different instrumentation to be used such as questionnaires,

interviews, observations and evaluation forms. The respondents are included

where they will be the ones to use and support the researchers proposed

system. The procedure talks about the methods of collecting the data through the

administration of the instruments.

Analytical tools aims to define each tool such as the context diagram, data

flow diagram and program flowchart. Statistical tools will formulate the stated

problems for the proposed system. The software development model is also

included in the chapters content and also the specifications of software and

hardware that is useful in running the proposed system.

Research Design

21

8/3/2019 Chap1 to 5

22/53


Descriptive Method of Research. This method focuses on design and

executing research so that issues such as planning, sampling, designing

measurement instrument, choosing statistical test, and interpreting results are

integral into research process. The type of research is also a grouping that

includes many particular research methodologies and procedures, such as

questionnaire, interview, observation and evaluation form. Descriptive research

was used when the objective is to provide a systematic description as factual and

accurate as possible. Applying these instruments, there is a greater

confidentiality possible because of personal contact, flexibility in giving up follow

up question and the opportunity to clarify things. In providing questionnaire the

responses are gathered in a more standardized way. (Black, 1999)

The researcher chose this method because it gives emphasis to the

process of accumulating a more accurate, fast and reliable solution for the

problem in existing system.

Instrumentation

This content is important for any study being conducted to consider the

manner of collecting relevant data. This study used questionnaire, interview,

observation, and evaluation form as instruments for gathering data.

Questionnaire. A form containing a set of question usually printed,

submitted form replies that can be analyzed for usable information. The

22

8/3/2019 Chap1 to 5

23/53


researcher will make a questionnaire that will be distributed for other users

for them to sight different aspect in making the project.

Interview. A formal meeting or conversation in which one or more person

consults or evaluates other person. There are guide questions prepared

by the researcher in conducting an interview with people who encountered

the problem with the used of existing system.

Observation. The act or the faculty of observing on taking notice; the act

of seeing, or of fixing the mind upon, anything. Instance in viewing a fact

on a special purpose. Through this method, the researcher would be able

know what the user wants to improve in the system.

Evaluation Form. This instrument is used for the process of examining

the system element to find out the point to which specific properties are

existing. The researcher will give out evaluation forms to different users

who will be participating the proposed system and acknowledge some

improvements made in the existing system supported by the criteria made

by the researcher.

Respondents

The target respondents that were chosen by the researcher are composed

of different users. (16) Employees, (4) owners.

23

8/3/2019 Chap1 to 5

24/53


The researchers chose them because they can be able to distinguish the

difference of their existing system and from the researchers proposed system.

The respondents are the target users of the company on the system. Overall, the

total number of respondents is twenty (20).

Procedure

The proponents had distributed the questionnaires on the first week of

September 2009 to the selected respondents. After the questionnaires had been

answered by the chosen respondents, the proponents retrieved these

questionnaires and analyzed the data. After the analysis, the proponents had

conducted an interview in the company on the third week of September 2009. On

the fourth week of September 2009, the proponents had performed an

observation and checked if there would be a problem during the manual

operation of the company. Lastly, the proposed system will then be presented to

the user after the systems development.

Analytical Tools

Analytical tools serve as a planning tool which is used to make a graphical

representation of the systems components so that readers of the study will

24

8/3/2019 Chap1 to 5

25/53


clearly understand the system. The following analytical tools were used for

analyzing the existing and proposed system

Context Diagram. This is an overview of the system as a whole and

the entities that will interact with it. It uses shapes such as boxes and

circles to represent the system and the users. Lines are used to

indicate their relations.

Data Flow Diagram. It is a graphical representation of the flow of data

in a system. First, a context level is made to show the interactions

between the system and outside entities. A more detailed form is

shown in the exploded data flow diagram.

Program Flowchart. This is a schematic representation of a process.

It uses shapes to determine the input, output, decision, process

initialization and termination of the program.

Statistical Tools

The researcher used statistical tools in order to determine the difference

between the existing system and the proposed system.

Problem No. 1 What is the demographic profile of the respondents in

terms of:

1.1 Position
