1

00:00:01,020  -->  00:00:07,230
So we look at the demand through your system not let's get started with the work history.

2

00:00:07,680  -->  00:00:13,260
Let's begin by looking at the different types of users that the system supports along with what those

3

00:00:13,260  -->  00:00:14,780
users can do.

4

00:00:14,790  -->  00:00:16,030
There are groups of users.

5

00:00:16,080  -->  00:00:22,110
One is the regular user and the other is a staff member a regular user is the one who simply uses a

6

00:00:22,110  -->  00:00:26,570
system for bookmarking like the one we have seen in our Demel.

7

00:00:26,820  -->  00:00:32,430
Staff members are part of our company and they have all the privileges of a regular user but they can

8

00:00:32,430  -->  00:00:34,960
also have some additional capabilities.

9

00:00:35,010  -->  00:00:42,050
So let's review the capabilities of both these types of users Just type of user is the regular user

10

00:00:42,050  -->  00:00:42,360
.

11

00:00:42,410  -->  00:00:45,370
And let's look at the capabilities to this class diagram.

12

00:00:45,570  -->  00:00:51,210
So you are using the methods in the class diagram to describe the user's capabilities not that class

13

00:00:51,210  -->  00:00:51,870
diagrams.

14

00:00:51,900  -->  00:00:58,450
Simply describe the classes that make up a software on a class diagram is a human concept and gives

15

00:00:58,500  -->  00:01:04,410
you don't know what you are Melas it stands for unified modeling language and it is used to visualize

16

00:01:04,410  -->  00:01:06,410
the design office system.

17

00:01:06,570  -->  00:01:12,720
So he you to have a regular user who can bookmark an item since trillionaire lost three types of items

18

00:01:12,720  -->  00:01:13,900
to be a mugger.

19

00:01:14,010  -->  00:01:17,720
We have a separate method for bookmarking each one of those items.

20

00:01:17,970  -->  00:01:21,300
That is same web link same more we unsavable.

21

00:01:21,780  -->  00:01:29,770
Additionally a user can also rate bookmark a user can also review a particular bookmark.

22

00:01:29,820  -->  00:01:36,270
However the review will not be published on the Web site until it is approved by one of the editorial

23

00:01:36,270  -->  00:01:39,040
staff members.

24

00:01:39,810  -->  00:01:46,860
Next type of user is an email administrator who is a staff member email admin can do everything a regular

25

00:01:46,860  -->  00:01:48,120
user does.

26

00:01:48,150  -->  00:01:52,430
Hence you can see that email admin has all the methods that a user has.

27

00:01:52,680  -->  00:01:56,410
Methods that are unique to email admin are emphasized in green.

28

00:01:56,460  -->  00:01:59,540
You can see the most posted a view is also shown in green.

29

00:01:59,580  -->  00:02:01,770
All the user class has that.

30

00:02:02,130  -->  00:02:06,780
And that's because email admins posted a few works slightly differently.

31

00:02:07,140  -->  00:02:14,760
Unlike user email admin does not need any approval for posting a review email admin also has a new method

32

00:02:14,880  -->  00:02:22,500
called handle mail campaign to periodically rants email campaigns with large numbers of emails are sent

33

00:02:22,500  -->  00:02:24,050
out to its users.

34

00:02:24,380  -->  00:02:30,870
And sometimes these email campaigns might get stuck and it would be the responsibility of image admin

35

00:02:30,960  -->  00:02:32,730
to fix the issue.

36

00:02:32,730  -->  00:02:40,420
So this new method is related to handling of such problematic email campaigns.

37

00:02:40,560  -->  00:02:47,510
Next type of user is a continuity teacher who is also the staff member unlet email admin a continuity

38

00:02:47,510  -->  00:02:53,700
there can also do everything a regular user does and does not need any approval for posting a review

39

00:02:53,720  -->  00:02:54,170
.

40

00:02:54,600  -->  00:03:01,200
Additionally Khond continued results are responsible for approving and rejecting reviews posted by regular

41

00:03:01,200  -->  00:03:06,180
users so use the separate methods for both these activities.

42

00:03:06,180  -->  00:03:09,960
If a review is rejected then it will not show up on the website.

43

00:03:10,390  -->  00:03:15,810
Continuity itor is not responsible for handling problematic email campaigns and hence you don't see

44

00:03:15,810  -->  00:03:18,020
a method for that.

45

00:03:19,110  -->  00:03:24,670
Undefined final type of user is a chief content editor who is also a staff member.

46

00:03:24,950  -->  00:03:31,770
It Chief Content Editor can do everything a content editor does and in addition is also responsible

47

00:03:31,830  -->  00:03:38,230
for managing the homepage content that is he or she decides what goes on the homepage.

48

00:03:38,310  -->  00:03:44,730
Most recently book martyrdoms are the ones that go on the homepage hollower some of the book martyrdoms

49

00:03:44,880  -->  00:03:51,090
may not be appropriate to be shown on the homepage unswitched Chief Content Editor acts as a moderator

50

00:03:51,660  -->  00:03:56,490
and makes the final judgment on what can be pushed on to the homepage.

51

00:03:56,490  -->  00:04:03,200
So basically a chief editor can do everything as a regular user does and also everything a content or

52

00:04:03,200  -->  00:04:05,250
network can do.

53

00:04:05,250  -->  00:04:06,720
And that's about it for now.

54

00:04:06,910  -->  00:04:09,920
And it would help us to get started the next chapter.

55

00:04:09,930  -->  00:04:13,620
New features will be introduced later as we learn some more topics.

56

00:04:13,620  -->  00:04:14,550
Thank you.
