Design and Implement a Computerized System for File Sharing and Access Control
Design and Implement a Computerized System for File Sharing and Access Control
ABSTRACT
Technology has proved beyond all reasonable doubts that computer technology can eliminate the burden of the manual systems which has been affecting administrative activities.
The file is the collection of records. It holds data that is required for providing information both for present and future reference. It plays a vital role in every organization.
The present system is being reviewed and problem that is associated with it includes the inability to effectively handle files, data security, batch processing, misappropriation of data, abnormal indexing, file location, misplacement of files, updating of records, transfer of files, etc.
All these problems occur due to manual sharing of files and records hence the need for a computerized file sharing and access control system. This system will help in eliminating all those problems encountered in the manual system; it will promote good administrative activities and dissemination of information on-timely basis if implemented.
The method used in solving this problem is based on a top-down approach. This is done by starting with the general concept of what is required by the existing system that it is lacking and breaking them into component parts which are then simplified with the introduction of the new system.
The use of file and file sharing in this context is based upon the modular approach of programming.

INTRODUCTION
Almost all information stored in a computer must be in a file. Each document is stored in the computer individually by name in what is called a FILE. A file is a collection of letters, numbers, and special characters.
It may be a program, a database, desertion, a reading list, a simple letter, etc, there are many different types of files; data files, text files, program files, directory files, and so on. Different types of file stores different types of information. For example, program file stores programs whereas text files store text.
In today’s information age, where every success is dependent on fast storage, access control, and retrieval of information. Computer file and filing techniques have gained more attention. Files in a programming sense are not really very different from other forms of file or other applications.
The biggest difference is that in a program you access the file sequentially (you read one line at a time starting at the beginning) and also when you can write by creating a new file from scratch (or overwriting an existing one) or by appending to an existing one.
