Computer Science Project Material with Source Code Included


The principal objective of this project is to help Database Security Systems (DIS) especially NIGERIAN POLICE which is my case study in the area they encounter problems in securing security data processing and efficient information system. This will be the solution given to handle this problem by transforming the existing manual information system into an automated form and overcome the existing problems of insecurity and delay in data processing. I decided to use an automated database system to enhance Information storage and keep track of security information. Again, doing this will ensure that there is an effective Database Security System computerization. To achieve this, Visual Basic 6.0 is used for its implementation.

Chapter One

1.0 Introduction

National security is the requirement to maintain the survival of the state through the use of economic, security operatives especially police, political power and the exercise of diplomacy. The concept developed mostly in the United States of America after World War II focusing on the police and military might. Now, it encompasses a broad range of facets, all of which impinge on the police and military for economic security of the nation, lives property and values protected by national society. Accordingly, in order to possess national security, a nation needs to possess economic security, energy security, environmental security, etc. Security threats involve not only conventional foes such as other national states but also non state factors such as violent non-state actors, narcotic cartels, multinational corporations and non-governmental organizations; some authorities include natural disasters and events causing severe environmental change in this category.

The origin of the modern concept of “national security” as a philosophy of maintaining a stable nation state can be traced to the peace of Westphalia, wherein the concept of a sovereign state, ruled by a sovereign, became the basis of a new international order of nation states.

As an academic concept, national security can be seen as a recent phenomenon which was first introduced in the United States after World War II, and has to some degree replaced other concepts that describe the struggle of states to overcome various external and internal threats. The struggle of states to overcome various external and internal threats. The earliest mention of the term national security, however, was made in Yale University in 1790 wherein was made to its relation with domestic industries.

The concept of the national security became an official guiding principle of foreign policy in the United States when the National security Act of 1947 was signed on July 26, 1947 by the U.S. President Harry S. Truman. Together with its 1949 amendment, this act create American national security d important facets for American national security as the precursor to the department of defense, subordinated the security operatives branches to the new cabinet level position of the secretary of defense, established the National Security council and the Central Intelligence Agency. The Act did not define national security which was conceivably advantageous as it’s ambiguity made it a powerful phrase to invoke whenever issues threatened by other interests of the state, such as domestic concerns, came up for discussion and decision making.

The realization that national security encompasses more than just security was present though understated, from the beginning itself.

The US National Security Act of 1947 was set up “to advise the president on the integration of domestic security and foreign policies related to national security”.

Gen Maxwell Taylor’s essay of 1947 titled “The Legitimate claims of National Security” has this to say;

The national valuables in this broad sense include current assets and national interests, as well as the sources of strength upon which our future as a nation depends. Some valuables are tangible and earthly; others are spiritual or intellectual. They range widely from political assets such as the Bill of Rights, National Security and political institutions and international relations to many economic assets which radiate worldwide from a highly productive domestic economy supported by rich natural resources. It is the urgent need to protect valuables such as these which legitimizes and makes essential the role of national security.

1.1 Statement of the Problem

Database Security system has always played a vital role in the stability of a nation. Keeping security information manually can hinder some defense program and delay passage of security information to the appropriate body. Manual documentation of security information can lead to exposure of the information thereby creating threat to the nation at large. Hence, there is need for an automated Database Security System to guaranty safety of information.

1.2 Objectives of the Study

The general objective of the study is to develop a database for security information storage and retrieval.

Specifically, the following objectives are also considered:

  1. To build a database system for police security information.
  2. To develop a software for managing security information.
  3. To determine the effectiveness of Nigerian police in managing signal.

1.3 Definition of Terms / Variables


Policing is another way of depicting the police.


Anti-policing is the society’s social attitude opposed to war between states and in particular countering arguments based on policism.


A systematically arranged collection of computer data, structured so that it can be automatically retrieved or manipulated. It is also called a databank.

National Security:

The requirement to maintain the survival of the nation-state through the use of economic, policing, and political power and the exercise of diplomacy.

Information Security:

Means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording, or destruction.

Classified Information:

Is sensitive information to which the access is restricted by law or regulation to particular groups of persons.

Security Management:

Is a broad field of management related to asset management, physical security and human resource safety functions.

Summary, Recommendation and Conclusions

5.1 Summary

Information in its most restricted technical sense is an ordered sequence of symbols that record or transmit a message. It can be recorded as signs, or conveyed as signals by waves. Information is any kind of event that affects the state of a dynamic system. As a concept, however, information has numerous meanings.

Moreover, the concept on information is closely related to motions of constraint, communication, control, data, form, instruction, knowledge, meaning, mental stimulus, pattern, perception, representation, and especially entropy.

The measures adopted to maintain national security in the face of threats to society has led to ongoing dialectic, particularly in the liberal democracies, on the appropriate scale and role of authority in matters of civil and human rights.

Tension exists between the preservation of the state (by maintaining self-determination and sovereignty) and the rights and freedoms of individuals. Although national security measures are imposed to protect society as a whole, many such measures will restrict the rights and freedoms of all individuals in society. The concern is that where the exercise of national security laws and powers I not subject to good governance, the rule of law, and strict checks and balances, there is a risk that “national security” may simply serve as a pretext for suppressing unfavorable political and social views.

5.2 Conclusion

For much of police history the armed forces were considered to be for use by the heads of their societies, until recently, the crowned heads of states. In a democracy of other political system run in the public interest, it is a public force.

The relationship between the police and the society it serves is a complicated and ever-evolving one. Much depends on the nature of the society itself and whether it sees the police as important, as for example in time of threat or war, or a burdensome expense typified by defense cuts in time of peace

5.3 Recommendation

The following recommendations are made:

That this system be implemented by Nigeria police to enable them go into computerized information system.
Also schools should expose students to some more relevant programming languages like visual basic so as to enable them carry out their projects on their own.

Libraries should b well equipped to simplify the work for the students and especially during the research phase.
These relationships are seen from the perspective of political police relations, the police industrial complex mentioned above, and the socio-police relationship. The last can be divided between those segments of society that offer for the police, those who voice oppositions to the police, the voluntary and involuntary civilians in the police forces, the populations of civilians in combat zone, and of course the police self-perception.

Police often function as societies within societies, by having their own police communities, economies, education, medicine and other aspects of a functioning civilian society. Although a police is not limited to nations in of itself as many private police companies (or PPC’s) can be used or “hired” by organizations and figures as security, escort, ot other means of protection where police, agencies, or militaries are absent or not trusted.
