    Design and Implementation of Information Management System

    CHAPTER ONE

    1.0 Introduction

    Information systems have become the backbone of most organizations. Banks could not process payments, governments could not collect taxes, hospitals could not treat patients, and supermarkets could not stock their shelves without the support of information systems. In almost every sector− education, finance, government, health care, manufacturing, and businesses large and small− information systems play a prominent role. Every day work, communication, information gathering, and decision making all rely on information technology (IT). When we visit a travel agency to book a trip, a collection of interconnected information systems is used for checking the availability of flights and hotels and for booking them. When we make an electronic payment, we interact with the bank’s information system rather than with personnel of the bank.

    Modern supermarkets use IT to track the stock based on incoming shipments and the sales that are recorded at cash registers. Most companies and institutions rely heavily on their information systems. Organizations such as banks, online travel agencies, tax authorities, and electronic bookshops can be seen as IT companies given the central role of their information systems.

    Information Management System (IMS) is a general term for software designed to facilitate the storage, organization and retrieval of information.

    IMS is also the name of IBM’s mammoth software program developed in the 1960s to support NASA’s Apollo space program. This IMS version was the precursor to IBM’s premier hierarchical database management system (DBMS).

    Electronic document and records management system (EDRMS) is a type of content management system and refers to the combined technologies of document management and records management systems as an integrated system.

    Unlike DB2 (IBM’s relational database software), an IMS database uses segments, or data blocks, as building blocks of the hierarchical model. Within each segment are multiple data pieces, which are known as fields. At the top of the hierarchy, the segment is known as the root segment. Segments of a specific segment are known as child segments. The child segment order represents the order in which each entry is entered in a database.

    Hierarchical IMS databases generally come in three forms:


    1. Full function database:

    Derived from the Data Language Interface (DL/I), this database form may have more than one single access method. Overflow Sequential Access Method (OSAM) or Virtual Storage Access Method (VSAM) may be used to store and access database fields.


    2. Fast path database:

    Designed to facilitate an optimum transaction rate. Examples are data entry databases (DEDB) and main storage databases (MSDB).


    3. High availability large databases (HALDB):

    Handles large volumes of data and provides reliable availability for each piece of data in the database.

    IMS (Information Management System) is a database and transaction management system that was first introduced by IBM in 1968. Since then, IMS has gone through many changes in adapting to new programming tools and environments. IMS is one of two major legacy database and transaction management subsystems from IBM that run on mainframe MVS (now z/OS) systems. The other is CICS. It is claimed that, historically, application programs that use either (or both) IMS or CICS services have handled and continue to handle most of the world’s banking, insurance, and order entry transactions.

    1.1 Background Of The Study

    Paper-based Information management system are rapidly becoming outdated. They are easily lost, are subject to wear and tear, are costly to handle, cannot be transferred electronically, may be difficult to interpret, and are inefficient. These fundamental drawbacks are driving a transition across the globe towards Electronic Health Records (EHRs).

    This research work offers a practical solution using cryptography to protect these sensitive electronic records of students and staffs in computer science department, Federal college of Agriculture,Ishiagu, and gives them privacy control over who views their records, details and every other sensitive information in other units of the school.


    1.2 Statement Of The Problem

    Computer science department of Federal college of Agriculture is to an extent manually operated and manage records and data. The recording of students admitted and their activities are done manually in a book, which looks/appears rough. Thus, the books or files are exposed to physical damage by ants and pests, accumulation of dust particles; this makes the contents to be lost, misplaced or even altered.


    1.3 Purpose Of The Study

    The purpose of this study is to develop software that can be used in information management system students received with its activities. Also to promote efficient and quality of services to individuals

    1. Capture the basic data in the departmental unit of Federal College of Agriculture: where students can view their file.
    2. Protect sensitive information at the various department using user login security and triple DES encryption method there by assigning unique decryption key for each user which works when.

    1.4 Significance Of The Study

    This study is primarily aimed at computerizing the manual system of information management system as used in the departments of FCAI. It will help in a good number of ways to ease the process of retrieving data and records in the system.

    This study will also highlight the importance information management system to an organization and business centers too.


    1.5 Objectives Of The Study

    The major objectives of this study is aimed at developing a system for the management of information others include

    1. To save time (fast inputting and accessing of records)
    2. To enable the management to plan ahead
    3. To reduce fatigue of the staff
    4. To ensure accuracy in the records of information
    5. To ensure safety of the documents/records/data/information, because the system will be password aid to reduce access.
    6. To ensure integrity of the records
    7. To ensure consistency of accounts and reduction of error due to damage of information
    8. To reduce forgery and loss of information by theft

    1.6 Scope Of The Study

    The scope of the study covers the polytechnic as a whole and only the management staffs and students of the institution

    Though, the scope is in such a way that the study can be carried out in one and only way that is computerizing the student information. This will help to modernized the inherent problems encountered by the managements of this organization


    1.7 Limitations Of The Study

    This research work thou is on information management system but it is dependent on human operation and manipulation in other to perform its work effectively.

    Also this research work is limited to power supply as it happens to be the only source of energy therefore without power holding the system cannot work.

    Finally this research work is constrain and limited to computer literate those who can operate a computer system effectively and its operation therefore a computer illiterate cannot make use of this research work as expected.
