What are the differences between serial file organization and sequential file organization?
Serial file organization stores records in a linear format, while sequential file organization stores records in a specific order defined by a key field. In serial file organization, records don't have to be retrieved in a specific order, whereas in sequential file organization, records are retrieved based on the key field's order.
What are the advantages and disadvantages of indexed-sequential file organization?
Advantages of indexed-sequential file organization include efficient access to records through an index and sequential storage for faster retrieval. However, disadvantages may include increased complexity in managing the index and potential performance degradation due to index maintenance overhead.
What are the primary advantages to using data file?
The primary advantages of using data files include easy storage and retrieval of large amounts of data, improved data organization and structure, and increased data security and protection.
What are the significance of choosing an appropriate file organisation for data?
There are several methods of file organisation and each one is suited for a particular task or purpose. Here are the factors to consider before choosing a file organisation method; 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. 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. File access method: Definitely different files have different methods of being accessed, example a reference file is accessed using random method for easy retrieval of data. 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. Master file medium: The master file 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.
