What is the Similarities of manual filling system and computer filling system

Answer:
What are the similarities between database system and file system at the low level?
There basically aren’t any low level “similarities” between database systems and filesystems. At a high level they are both systems for storing data “persistently” (that is, such that the data will be accessible even after a reboot or complete power cycle). They each offer means for accessing specific items and even specific portions of specific items.
That’s about it.
They are far more comparable in terms of their differences than their similarities.
For example databases are usually stored in files, which exist in filesystems. That is to say that a database using consists of files which can be found in a directory structure and which generally follow naming conventions (patterns) set by the manufacturer of the DBMS.
Databases are usually structured … they consist of tables which consist of rows which consist of columns and are constrained such that all the data within any column is of some given type.
Databases typically have some special tables which describe all the tables created and maintained by their users. These special tables control the RDBMS itself and those which describe the other tables are referred to as a database’ “schema.” A typical modern RDBMS can host multiple databases each with its own schema.
Filesystems generally provide hierarchical directory structures and relatively free form filenames. The filesystem typically treats file contents as simple unstructured streams of data; it generally imposes no “record” structure nor “schema” on the data. Applications are free to structure data within their file in any way that the programmers choose. They use some operating system primitive functions (system calls) to implement these structures (open, read, write, seek, tell).
Some operating systems uses “database” like indexing for the contents of their directories and for their metadata (the bits of the filesystem which are not file contents … but which associate files with data and maintain the logical sequential ordering of blocks regardless of any physical fragmentation). Some filesystems add metadata (checksums, even data redundancy) to their data for increased resilience, performance, or both.
Some very old operating systems did not have filesystems as we understand them. But this is not the case for any modern general purpose operating system and even deeply embedded operating systems today typically have filesystems … even if they’re only in RAM or non-volatile memory.
MANUAl FILING SYSTEM
1.) a man may forget the information stored in his mind.
2.) a man need more time to do any work as compared to a computer.
3.) a man can many mistakes.
4.) women need rest after working for sometime. 5.) a man can take his own decisions.
6.) man does not need any orders to work.
7.) a man has feelings for example, if you pinch your friend softly he feels it.
Computer filing system
1.) computer store a large amount of information and never forget it.
2.) computer work very fast and can do many jobs at the same time.
3.) a computer does not make any mistakes.
4.) a computer does not get tired and can work for long hours.
5.) a computer cannot take it ows decisions.
6.) a computer work on man's order.
7.) a computer does not have any feelings for example, if you pinch a monitor it does not react.
