File-Based Approach File-based approach is the preliminary approach to data storage. It is based on relatively simple data structures, such as the Indexed Sequential Access Method, and is usually implemented for a single application. Files are generally created on an as needed basis to service the data needs of an application. The files are associated with an application. A file-based data storage approach makes it difficult for other applications to access data not owned by their application. Because the physical storage characteristics of the same data may be different for different applications, therefore data owned by one application may be stored in a format not consistent with the retrieval capabilities of another application. This causes inconsistency while updating data files across the organization. The primary reason it is that the File-based approaches to data storage are tied to applications rather than the entities/ objects to which the f...
