context and data flow diagram request

play00:02

Amazon online shopping system now the

play00:05

following is a request from one of my

play00:06

viewers Benham and he would like me to

play00:08

look at Amazon and within the context of

play00:10

its Depot finance and product

play00:12

distribution so let's firstly have a bit

play00:14

of a look at what Amazon does now Amazon

play00:16

is one of the biggest businesses in the

play00:17

world and a pioneer in the area of

play00:19

e-commerce Amazon starters was the first

play00:22

major online shopping sites where people

play00:24

from across the world could go online

play00:25

and search their catalogue purchasing

play00:28

items which would then be delivered to

play00:30

their door wherever in the world that

play00:31

might be Amazon has expanded into the

play00:33

areas of digital products and streaming

play00:35

services these days and continues to be

play00:37

a powers on the global market so as said

play00:40

today we're gonna look at Amazon's

play00:41

traditional business model of selling

play00:43

physical product within these corporate

play00:44

index of depo finance and products so

play00:47

firstly we'll take a look at a context

play00:49

diagram trying to give us a bit of idea

play00:51

about the external entities and what

play00:53

impacts on actual Amazon system so here

play00:56

is Amazon system the customer accesses

play00:59

the system through their account details

play01:00

and the customer types in a search

play01:03

criteria to look for specific products

play01:05

and when they see products they like

play01:06

okay they select them and they add them

play01:08

to their cart obviously which is stored

play01:10

within Amazon once they've got a few

play01:12

items I like the next step there is a

play01:14

payment request to their bank and

play01:16

essentially to buy all the things stored

play01:18

in their shopping cart the bank will

play01:20

then give them an approval they'll pay

play01:21

for the customers products provided

play01:23

they've got the money to pay for them

play01:24

otherwise they'll be declined and then

play01:25

the customer will get a receipt of the

play01:27

transaction these products will then be

play01:29

packaged by Amazon sent to the customers

play01:31

door now this is obviously one side of

play01:34

the customer and essentially their

play01:35

interaction with Amazon's online system

play01:37

but we've got to think what's happening

play01:39

within Amazon people are buying products

play01:40

the products are decreasing in quantity

play01:42

Amazon then needs to purchase more

play01:44

products so essentially the next step in

play01:46

this system is Amazon needs to contact

play01:48

suppliers okay and what they do is

play01:50

create a purchase order saying we need X

play01:52

amount of new products okay to restock

play01:55

in order to keep able customers buying

play01:59

these products so a purchase order is

play02:01

sent to the supplier the supplier will

play02:03

then give me an invoice saying although

play02:04

if you want this amount of products it's

play02:05

gonna cost you this amount of money okay

play02:07

Amazon then like any other business or

play02:09

individual needs to contact their bank

play02:11

okay

play02:12

their payment request is sent for the

play02:13

purchase order products okay the bank

play02:15

then will give their confirmation so the

play02:17

payment for the ordered items Amazon

play02:19

then can pay for the stock from the

play02:21

supplier okay and the supplier will give

play02:23

a receipt from the transaction okay so

play02:26

just a bit of context there about how

play02:28

this is working but the big thing we've

play02:29

always got to look at is a data flow

play02:31

diagram illustrating all of this so

play02:33

let's begin so firstly as we said we've

play02:36

got the customer they're typing in

play02:37

Amazon's URL and they go to the website

play02:39

in order to get into the actual business

play02:41

side of the website so they can actually

play02:43

start buying products okay then either

play02:45

enter in their login and password okay

play02:47

which will be checked against a customer

play02:49

details but database and if the account

play02:51

matches they're approved from here they

play02:53

can start navigating the website so they

play02:55

enter in a search criteria in order to

play02:57

search items okay and this allows them

play02:59

to have a look through amazon's product

play03:01

database okay so they can see all the

play03:04

products that are stored within them

play03:05

based on that search criteria when they

play03:07

want to view a specific item they will

play03:09

click on the specific item and the

play03:11

specific items details are retrieved

play03:12

from that product database okay and they

play03:14

get all the information about that now

play03:16

if they like a specific item they are

play03:18

obviously going to click Add to Cart

play03:19

okay and that gets added to their

play03:21

shopping cart all right so from this

play03:24

point near they could be going to lots

play03:26

of different pages and sing lots of

play03:27

different products okay and adding more

play03:29

and more products to their shopping cart

play03:31

now as said these card items need to be

play03:34

stored somewhere and that's obviously

play03:35

going to be stored on the customer

play03:37

details database so if they'll leave the

play03:39

website now come back at a later day

play03:40

these items should still be stored

play03:42

within their customer details from here

play03:46

now we need to make our purchase and

play03:48

we're obviously purchasing the items

play03:49

that are stored in the shopping cart

play03:50

that's the step so at this next process

play03:53

we need to retrieve that data from the

play03:55

customers database okay so we can

play03:57

actually calculate the totals and how

play03:59

much all this is going to cost in order

play04:00

to purchase the items always then at

play04:02

this point we're now going to contact

play04:04

the bank okay so whatever the total cost

play04:06

is of all these items in the shopping

play04:07

cart it gets sent to the bank a request

play04:10

is made and then the bank will give an

play04:11

approval the items get purchased so the

play04:14

purchase is made Amazon will need to

play04:16

record this as a new record in their

play04:18

transaction database saying this

play04:20

purchase has been made at this date and

play04:22

this much was paid from here okay the

play04:24

transaction is Dean

play04:25

successful we generate a receipt for the

play04:27

customer and the customer gets their

play04:29

receipt obviously might be emailed them

play04:31

displayed on screen whatever and they

play04:33

may also get an actual receipt stored on

play04:35

their actual database as well so they

play04:37

can backtrack it and use stored

play04:39

somewhere on Amazon's actual databases

play04:40

from there so that's it for the

play04:43

transaction part with the customer

play04:45

purchasing the actual items from here

play04:48

now we're going to look at the Depot the

play04:49

actual sending of the products to the

play04:50

customer so at this point the customer

play04:53

order then would be sent into actual the

play04:55

factory ok and Amazon me I would have to

play04:58

put all the items together we need the

play04:59

package or these items so we can send

play05:01

them to the customer ok so they'd

play05:03

package all the items based on an order

play05:04

report that would either be generated

play05:06

someone would look at that order report

play05:07

collect all the items ok and then

play05:09

actually package it up for the customer

play05:11

from here once the order is compiled

play05:13

delivery needs to be scheduled so we

play05:15

schedule the delivery ok for a specific

play05:17

day ok that date then would need to be

play05:19

stored on a delivery database so the

play05:21

delivery details would be sort on a

play05:23

delivery database so that we can see

play05:25

when we're planning on sending something

play05:26

out and saying basically it's ready to

play05:29

go once the delivery gets sent we need

play05:32

to log that little delivery was sent

play05:34

okay so the delivery has been dispatched

play05:36

it was sent to this day and obviously

play05:38

that will be stored on the database too

play05:40

so the time of distribution will be sent

play05:42

this date at this time and also as we

play05:45

know with a lot of products they've got

play05:46

RFID on them tracking data would be

play05:48

stored on the product too because

play05:49

remember Amazon's selling products

play05:51

globally they can get lost in many ways

play05:54

shapes or forms okay so the tracking

play05:56

data will probably stored on a delivery

play05:57

database as well so they can track the

play05:59

products as they're being delivered to

play06:00

their actual customers so that's it with

play06:03

the delivery side ok of what's happening

play06:05

with Amazon's products from there the

play06:08

next thing we're gonna look at is

play06:09

essentially as we said when we're at

play06:11

generate the order of their of the

play06:13

customer we're getting all these items

play06:15

so this is where the item quantity

play06:17

within Amazon's databases are getting

play06:19

depleted ok so obviously after this they

play06:22

need to purchase more products so we're

play06:24

going to go back to the generate

play06:25

customer order of box I think that's

play06:27

when the products of quantity is

play06:28

dropping from here we need to deduct the

play06:31

purchase items ok from the product in

play06:34

inventory so we need to update the

play06:37

product quantity and by updating or

play06:38

saying we

play06:39

less of that product now and that needs

play06:41

to go into the product database okay and

play06:43

that also links back to when customers

play06:46

of viewing items and they can see the

play06:47

product is out of stock and they can't

play06:48

really purchase it that goes for a lot

play06:50

of online shopping sites okay so the

play06:52

product gets updated okay when it's

play06:54

reduced stock and stored in the product

play06:56

database now once a product does get to

play06:59

a low quantity from here we need to flag

play07:01

the item and say this products quantity

play07:04

is low okay in order for Amazon to be

play07:06

successful they need to be replenishing

play07:08

their products before they run out of

play07:10

them because thousands of people are on

play07:12

Amazon site at a time and basically if

play07:15

they can't sell them the products they

play07:16

want they're losing a thousands of

play07:18

dollars okay so they need to flag the

play07:20

item and say the item is low in stock

play07:22

from here this is where the ordering

play07:24

process starts so they need to order the

play07:28

items that are low and they generates

play07:29

that purchase order that we saw in the

play07:31

context diagram okay so they put the

play07:33

purchase order together they say we need

play07:35

this amount of items and then the next

play07:37

step is they need to contact the

play07:38

supplier they probably have a suppliers

play07:40

database and that's where they access

play07:42

the supplier details from so this

play07:44

purchase order would be sent to the

play07:46

finance department ok the finance the

play07:48

pump would process the invoice ok and

play07:50

then they would obviously make the

play07:52

request of the supplier ok so they put

play07:54

an invoice together and say we need

play07:56

these amount of products the supplies I

play07:58

was going to send back ok the employees

play08:00

saying this is how much it's going to

play08:02

cost you guys now at this point the

play08:03

finance department would probably say

play08:05

yep it's ok but they do it have every

play08:07

chance at this point saying that we're

play08:08

not paying that

play08:09

and they won't autumn or they might try

play08:11

to find a different supplier but

play08:12

essentially once they get the invoice

play08:14

back and they think it's ok in a fair

play08:16

price ok they will approve it and then

play08:18

they're going to pay the supplier in

play08:19

order for Amazon to pay their supplies

play08:22

they need to contact their own bank so

play08:24

the items cost goes to Amazon's bank

play08:26

they approve it the supplier can be paid

play08:28

so the player supply will get paid by

play08:30

Amazon's bank they will get a receipt

play08:32

from the supplier ok and that will

play08:34

likely be stored in the suppliers

play08:36

database that another transaction taking

play08:38

place this is how much they paid for

play08:40

these products ok and it happened on

play08:42

this date so we've retained that data

play08:44

about purchasing from the supplier for

play08:46

future reference the next step from here

play08:49

is the items will get delivered Amazon

play08:50

ok that's the next time that

play08:53

happen in this actual system the

play08:55

supplier will send him to Amazon they

play08:57

will receive the delivery and obviously

play08:58

once they've received the delivery they

play09:00

need to update their product quantity

play09:02

again and replenish those items they've

play09:03

got more of the quantities that were

play09:05

running out of product so need they

play09:06

record that on their actual updated

play09:09

database so that will get stored once

play09:11

again on their product database so I

play09:13

hope you can understand what's going on

play09:15

here when you look at this at the end it

play09:16

looks like an absolute complete mess but

play09:18

I hope it gives you a good understanding

play09:20

of what goes on in the bigger picture of

play09:22

Amazon's online business essentially

play09:24

what happens at the customer's end when

play09:26

they're going online looking at items

play09:28

purchasing them

play09:29

okay contacting their bank okay so they

play09:31

can have these obviously buy items

play09:33

online what happens on Amazon's end when

play09:36

they need to send these products to the

play09:38

actual customer after they're being

play09:40

bought and essentially as well what

play09:42

happens when Amazon's inventory gets

play09:43

light and then they need to buy items

play09:44

from their supplier and the processes

play09:46

they go through so Benham this was a

play09:48

great suggestion I really enjoyed making

play09:50

this I hope it makes sense here and a

play09:52

hope was a good help
