Describe the approach taken to handlin of data in the early file based system?
Mahmoudsaad
Focus was on applications for which programs would be written, and all the data required would be stored in a file or files owned by the programs.
Clearly, each program was responsible for only its own data, which could be repeated in other program's data files. Different programs could be written in different languages, and would not be able to access another program's files. This would be true even for those programs written in the same language, because a program needs to know the file structure before it can access it.

Describe the approach taken to the handling of data in the early file-based?
In the early file based system their all data was in written form, due to the lake of education, due to the in-femelarity with new techniques, lake of computer knowledge so all the data required would be stored in a file or files owned by the programs. Clearly, each program was responsible for only its own data, which could be repeated in other program's data files. Different programs could be written in different languages, and would not be able to access another program's files. This would be true even for those programs written in the same language, because a program needs to know the file structure before it can access it.
What is the difference between traditional file based approach and database approach?
There are significant differences in physical implementation of how data is stored and used. A database allows for data to be recorded in related structures with optimization aligned to the goals of the model for efficient use. The classes or record types in a database could be considered like lists in a file, though within the framework of the database management system (dbms) that relates, stores, indexes, retrieves, and updates the data in place. Ordinarily, file-based storage is for simpler, less structured lists that do not need to be related to data in other files as dynamically as a database. In practice, their use is significantly different, but conceptually there are many overlaps. One could denormalize the data in a database into a set of files suitable for some data processing needs, and databases are implemented in system files that are managed by the dbms, through which the developer and user operate.
