Price: 2000 Naira
As the complexity and degree of crimes wider, system Nigeria new technology will have to be utilized to aid lawyers and criminologist to fight this tends, on computerized crime record will offer a solution on this issue. It is a software set up in order to meet the information needs of every part of the agency about crime record. The software is divided into four different sections: Criminal record, case record, cases and tutorial.
Crime record gives information on any offence selected by the user; case record store all relevant information on any case handled by the expert, case given already decided cases depending on the choice of the users tutorial teaches or explains certain thing son crime record. The aim behind the design of this software is to model a computerized crime record system to enable professional and non-professional to handle criminal related matters with ease.
1.1 Background of the Study
Security is the most vital aspect of every society all over the globe irrespective of the location. Conventionally the management of records and profile is in our police stations are done manually by writing on paper, filing and categorizing the collected data and storing them in a cabinet or shelves. This method is slow and painstaking as retrieval of this data involves searching through hundreds or thousands of files to retrieve a small piece of information depending on the size of institution.
With the introduction of computers and Information System (IS), the process of collection and management of data which involved record keeping and profile management in police stations has been tremendously improved as the speed of data collecting and retrieval increased significantly thereby making data management is a major driving force in the ongoing Information Technology (IT) revolution. The records of citizens (complainant/defendant) collected serve many purposes and pass through many corporate processes. The records are so important that the police channel much resource to preserve the integrity of the records.
However, over the last few decades, there has been significant improvement in data storage, data access, data protection and data distribution where data storage was once at a high premium that a single CD-ROM can now store 500MB of data. Rumours has it next generation of CD-ROMs will store at least ten times that amount but there has been challenges in the last few years to the traditional data security and access philosophies. The lessons learnt over the years show that the continuing importance of data and the increase in citizens’ records and profile no matter how it is accessed or packaged will undoubtedly play a central role in the health and competitiveness of police in the future, (Alter, 2002).
The history of information systems coincides with the history of computer science that began long before the modern discipline of computer science emerged in the twentieth century. Regarding the circulation of information and ideas, numerous legacy information systems still exist today that are continuously updated to promote ethnographic approaches, to ensure data integrity, and to improve the social effectiveness and efficiency of the whole process.
Before the concept of information systems was created, computer scientists were just programmers creating applications for science and math calculations. As computer usage evolved in fields of business and data management, software applications were needed to process nonscientific data.
1.2 Statement Of Problem
Various problems are encountered in the manual system of operations in any organization, so it is in the web based crime record and information system. Some of the problems encountered are:
i. Generating a crime filing number for each of the crime has been cumbersome because it is not easy to trace the file number of the last recorded crime and this has led to duplication crime File Numbers.
ii. Accuracy about dates of filling various components of the crime is not readily available making referencing them very cumbersome.
iii. Making references to existing Criminal cases is difficult because of the manual mode of documentation.
1.3 Aim Of The Study
The aim of this study is to design and implement of a web based crime record and information system for organization.
1.4 Objective Of The Study
Our Crime web based crime record and information system:
i. Help in the Reduction of redundancies and inconsistencies.
ii. Ensure user defined rules to ensure the integrity of data.
iii. Enable data sharing across all applications.
iv. Ensures data access authorization.
v. Have an automatic intelligent backup and recovery procedure of data.
vi. Improve Integrity
1.5 Significance Of The Study
Projects provide a flexible framework for engaging students in exploring curricular topics and developing important 21st century skills, such as communication, teamwork, and technology skills. In addition, students are motivated by the fun and creative format and the opportunity to make new friends around the world. For staffs and administrator, a web based crime record portal enables quick and easy management of crime record and information system.
1.6 Scope Of The Study
The research will center on the design and implementation of a web based crime record and information system for Abiolian Solutions Limited.
1.7 Limitation Of The Study
Usually, every work has some limitations and this study is not exempted.
The two major limitations of this study are the high programming technique as well as financial constraints. The high programming technique constraint in PHP, JQUERY and MYSQL prevents the researcher to have an in depth study and analysis on the subject matter. While the issue of financial constraint limits the frequency of investigation to/from the institution toward gathering the necessary information relevant for the study.
1.8 Definition Of The Study
HTML CODE: – HTML stands for Hyper Text Markup Language. It is a type of computer language that is primarily used for files that are posted on the internet and viewed by web browsers. HTML files can also be sent via email.
Markup language: – A markup language is a combination of words and symbols which give instructions on how a document should appear. For example, a tag may indicate that words are written in italics or bold type.
Web browser: -A Web browser is a software program that interprets the coding language of the World Wide Web in graphic form, displaying the translation rather than the coding. This allows anyone to “browse the Web” by simple point and click navigation, bypassing the need to know commands used in software languages.
File extension: – A file extension is the suffix at the end of a filename that tells a computer, and the computer user, which program is needed to open the file. Also called a filename extension, this suffix preceded by at least one period, is generally one to five characters long but the norm is usually three characters in length.
Email: – Email, also sometimes written as e-mail, is simply the shortened form of electronic mail, a protocol for receiving, sending, and storing electronic messages. Email has gained popularity with the spread of the Internet. In many cases, email has become the preferred method of communication.
TCP/IP: – This often used but little understood set of operations stands for Transmission Control Protocol/Internet Protocol. TCP/IP is the combination of the two and describes the set of protocols that allows hosts to connect to the Internet. In actuality, TCP/IP is a combination of “more than those two protocols, but the TCP and IP parts of TCP/IP are the main ones and the only ones to become part of the acronymthat describes the operations involved.
TEXT FILE: – A text file is a computerfile that stores a typed document as a series of alphanumeric characters, usually without visual formatting information. The content may be a personal note or list, a journal or newspaper article, a book, or any other text that can be rendered accurately in typewritten form.
Hyper Link:-A hyperlink is a graphic or a piece of text in an Internet document that can connect readers to another webpage, or another portion of a document. Web users will usually find at least one hyperlink on every webpage. The simplest form of these is called embedded text or an embedded link.
WWW: – acronym for World Wide Web.
