Data is apparently a simple thing to handle. It is chunks of binary numbers meaningfully segmented by descriptors. As those descriptors are linked, using various schemes, the attached chunks also get linked. And the whole thing becomes meaningful - to us, not to the computers. They are spiritual souls believing in karma. You tell them what to do with data. They will do it dispassionately, just as the holy book said. They show the same emotion, or rather lack of it, when dealing with a number, say, 5,000,000, whether that is related to a single deposit in a privileged back account or the total death toll in Covid-19.

What does the following junk mean?

Well, that is binary, serialized data.

Why binary? Because you see only 0s and 1s.

Whey serialized? Because it has a direction of linear flow. Something like this:

Why is it so?

Because you intend to store that piece of binary information in a "file".

What is so great about a file?

For an operating system, a file is nothing but a chunk of binary data identified by a handle. The handle is called "file name".

So?

An operating system has been traditionally storing the contents of a file - the binary mass - in a mechanical hard disk. And inside a mechanical hard disk, binary bits are arranged in concentric circles.

So it is clear that any program which wants to save a piece of information to the secondary memory for later retrieval has to find a way of converting its own in-memory, mostly proprietary data structure, into a binary stream. Also, it has to find a way of reconstituting the in-memory structure at a later date from the binary stream.

Those two activities are called serialization and deserialization of objects, respectively.

Presented below a real scenario:

The scenario is pretty simple. John wants to listen to Led Zeppelin's "Stairway to Heaven". He requests VLC to play the file Stairway_to_Heaven.mp3. VLC retrieves the binary chunk of the file named so and decodes it for you. Simple. A similar thing happens when you want to view the last scene of the movie Midway again.

Now John's friend across the globe wants to listen to the same song and does not have the required file. You send the same file through some chat client. The chat client does not do much by the way of computational manipulation of data. It just puts the same file in the body of an HTTP packet and sends it across.

In this fashion millions of files - mp3, mp4, zip, aac etc. - move across the serial lines of Internet.

But the same thing is not as easy when we have a simple scenario like this:

Now, when someone asks for John Doe's employment record, one would not be accused of being naïve for assuming that it would store the same in a single file, which just has to be loaded to an HTTP packet and sent across.

But we have not constructed the world of database to be so simple. It does not store data one file per object. Rather, it is stored in huge db files, which are directly accessed at a low level using hard disk heads and sectors.

So in response to the simple request mentioned above, the poor database has to go scavenging in a plethora of tables to retrieve the distributed records.

John Doe's or for that matter any emplyee's records are stored in such a structure:

The oldest standard demands that in this case we generate three different comma separate files in the following fashion:

emp_mst.csv

emp_id,fname,lname,dob,doj,department,manager

46,John, Doe,12-Jun-1981,01-Mar-2016,Product Design,23

prev_emp_dtl.csv

emp_id, serial_no, employer_name, start_date, end_date, start_des, last_des

46,1,AT&T,15-Aug-2003,01-Oct-2011,Trainee,System Analyst

46,2,Amazon,02-Oct-2011,28-Feb-2016,Software Engineer,Architect

emp_edu.csv

emp_id, institution, accomplishment, graduation_yr, grade

46, Rockdate HIgh School, HIgh School Graduation, 1999, A

46, Princeton University, Computer Science Major, 2003,A

Each row is a record of the relevant table. The first row is the header row comprising the column names. It is not repeated.

Both generation of the CSV files and their parsing back into tables are both hard tasks. A multi-billion dollar industry rests on that diffculty.
