Could you explain factors to consider when selecting file organization method?

Answer 1

When selecting a file organization method, it is important to consider factors such as access speed, ease of organization, security, and scalability. Access speed refers to how quickly data can be retrieved from the file system, which can be influenced by the organization method used. Ease of organization involves how easily files can be stored and retrieved in a logical manner. Security considerations include protecting data from unauthorized access or loss. Scalability is important for ensuring that the file organization method can accommodate a growing amount of data without compromising performance.

Answer 2

Here are the factors to consider before choosing a file organisation method;

1. Frequency of update: A file that needs to be updated every now and then needs an organisation method that will allow easy retrieval of information and ease of updating, example of such a file is the transaction file.

2. File activity: Different files have different activities, example a sort file is used to sort data in sequential order and therefore sequential method would be appropriate for such a file.

3. File access method: Definately different files have different methods of being accessed, example a reference file is accessed using random method for easy retrieval of data.

4. Nature of the system: Files that are used in a particular system will depend on the nature of the system i.e the suitable organisation method for that particular system.

5. Masterfile medium: The masterfile is the main file for keeping permanent updates of records from transaction files and other sources, the medium by which it is updated will determine the organisation method to be used.
