Filing system organization

Typical examples of hierarchical database systems arc the file system of personal computers or the organization of parts (e.g., a construction plan). In the case of car parts, the objects (e.g. B = rear suspension, E = right wheel, J = rim, K = screw) are... 

An organized document filing system must be maintained. This could be a paper file, an electronic document file, or a mixture of both. The equipment inventory system contains key information on the components of each system, their performance criteria and maintenance and calibration status. All documents including installation and performance documentation, as with other documents necessary to demonstrate the quality of the data, include SOPs for the qualification procedures, calibration, maintenance, personnel training, etc. If the manufacturer s operating, service, or maintenance manuals are used or cited in the operating procedures, copies of these manuals should be maintained. To facilitate retrieval, documentation should be stored in a central location and be indexed for easy retrieval. 

In this chapter, we ve examined ways to waste and to save time. The primary key to personal organization is to have a place for everything and have everything in its place, which reqnires the establishment and use of a personal filing system where all your business papers can find their final resting place. 

Organizing document files on a file system requires defining the document hierarchy, typically represented in the folder structure of the hard drive. This hierarchy is static and has to be defined in advance. Reorganization of multiple documents into a new folder hierarchy is tedious, requires copying or linking files, and leads to a deficit in organization structure. 

A scientific workspace editor is a tool that allows scientists to keep their work data supporting the ELN in a separate secure database area. It allows users to create, upload, organize, and share data in a usually less regulated manner than with electronic scientific documents. The principle intention of this tool is to allow the user to enter, work on, and share data in an intermediate secure repository. The user can enter data and keep them private until explicit release and does not need to keep data on paper or on a local file system. In summary, a scientific workspace editor allows the following ... 

The file organization module is the next level below the logical file system and translates what the user knows and... 

The basic file system accepts requests from the file organization module in the form of action required (read, write) plus a physical address in the form of cylinder, track, and sector and then invokes the device driver to action the request by activating the hardware (initiating a seek to the appropriate cylinder, activation of the appropriate read/write head for the correct track, and a delay while the correct sector rotates under the head). 

Gopher servers were organized as a hierarchical file system, but they differed fiom ftp servers in having each file associated with a specific MIME type which served to indicate in at least some measure the type of content encoded in the file. MIME types are sometimes referred to as metainformation about the content of file.
