The Design And Implementation Of An Attribute Filesystem

With the continuous development of computer technology, computer performance is increasing, the application of computer is becoming more and more common, the information stored in computers also grows at an alarming rate. In a computer, information may be stored on tens of thousands, how to organize and manage information more effectively has become a major topic of current research.Modern operating systems is still use file system for data organization and management, in order to improve the efficiency of data organization and management, we should strive to i mprove the ability of fiIe system for managi ng data.The traditional file system use path to manage files, means change the directory structure of file to path to identity a file uniquely. If User wants to find the file, he must remember the location of file that the full path name. It is a very difficult thing to remember all the location of files if that are a lot of files in file system.In order to solve the shortcoming of file system based on location in information retrieval, people put forward the file system based on content. But, in solving the problem of file system based on location, file system based on content also bring inconvenience to user at the same time. For example, it is ambiguous to search file, space overhead and so on.Based on the old file system cannot meet the requirements of users, this paper put forward a new using FUSE framework way to design a attribute-based file system, and then gives its implementation in detail. The system has function of manage directory and file like the other file system, but also realize the attribute-based query and files automatic classification function. This paper use FUSE framework which avoiding modify the system kernel to implement a user space file system, and the system is very stable and compatible with the POSIX standard.Finally, this paper does lots of tests on the implementation of system and writes the tested result. After testing, the system finished according to the design requirements and run stably.
