The entire project has been divided into three modules namely

1.User module
2.Document module
3.Security module

User Module
User management includes adding/removing users, setting/modifying the access rights of users, setting the properties of the document management system etc. The system may also provide a guest user account. The administrator may define Groups of users, which may have a common set of privileges. The Administrator must be able to add/remove, setting/modifying the access rights of such groups. He should also be able to remove users from the system.

Document Module
Document management includes adding new document categories, removing existing document categories, modifying access and other settings of existing document categories, download and upload of documents for read update operations etc. The system must be able to categorize the documents in an organized manner. All the documents should be stored in a centralized database and must be accessible from various locations.

The system must ensure that when an authorized user is modifying a particular file, it should not he accessible to any others until it is completely updated and saved. I he system should provide for searching of documents based on keyword, documents names, category etc.. The system should provide a tree view listing of document categories. Each user can view only those document categories that are accessible to him. The system should maintain logs that keep track of the history of the files.

Security Module
Security Module deals with the secrecy and protection of the desired documents. It consists of sub modules namely User module and Category module.User module operates in two modes: Administrator mode and User mode. The administrator may define Groups of users, which may have a common set of privileges.

The Administrator must be able to add/remove, setting/modifying the access rights of such groups. The administrator must set read-only or read-write permissions for each document category for every individual user. User mode enables the user to create a new account on specifying the personal details. The forget password entry enables the user to retrieve his/her password by answering to a secret question correctly.
