File Management
In the company which I am employed, we have employees which access one file at a time. We offer any user to access the file at any time, but if a user already have the file open. He or she cannot make any changes to the file, until the primary user close the following file. This will protect the file from getting damage by other users, or other problems which may occur. When considering a system that supports 5,000 users. Suppose to only wanting to allow 4,990 of those users to be able to access one file can be accomplish in many different ways.
Access control list can provide a greater control over file permissions when traditional UNIX file permissions are not enough. UNIX file protection provides read, write, and execute permissions for three user classes: owners, groups and other. An ACL provides better file security by enabling you to define file permissions for the owner, owner’s group, others, specific users, and groups. It also enables you to define default permissions for each if these categories. Another protection scheme that can be used is the universe access information applies to all users unless their name appears in the access-control list with different access permission. With this scheme you simply put the names of the remaining ten users in the access control list but with no access privileges allowed.
A file system management system is essential when dealing with the issues of file access and other services in an operating system. Access is important in a business or organization because certain data is vital and not for the view of every user.

... that tumultuous applause and similar other acts proceeded [(XXVII. 3, 8-18, 13-14), while the spectators of the superior order gave [their appreciation of the deeper and the more subtle aspects of a play sXXVII, 5, 6, 12, 16-17). During the medieval times the approval of the Spectators of the latter kind .came to bo considered appreciation par XLVUI excellence and pro-occupied tho experts or learned critics. They analysed its process in every detail with the greatest possible care in their zealous adherence of Bharata's theory of Sentiment (rasa) built upon what may bo called a psychological basis. But in spite of this later development of this aspect of dramatic cri- ticism it never became the preserve of specalists or scholars. Critic* never forgot that the drama was basically a social amusraent and as such depen- ded a gr eat deal for its success on the average spectator. Even the Natya- sastra has more than once very clearly said that the ultimate court of appeal concerning the dramatic practice was the people (XX. 125-126). Hence a fixed set of rules, be it of the Natyavcda or the Natyasastra was never considered enough for regulating the criticism of a performance. This seems to be tho reason why special Assessors appointed to judge the different kinds of action occurring in a play (XXVI. 6S-69), decided in co-operation with the select spectators, who among the contestants deserved to be rewarded. 6.
