We are going to discuss Structured
English.

We know that in the previous videos,
we have discussed hippo diagram,

we discussed structured
charts, we also discussed.

DFD and different
types of DFDs and all.

And there all in all cases, we had some
graphical representations.

Graphical representations are good enough,
so there is no doubt.

But different people can interpret graphical
representations in their own views.

So, to avoid that anomaly,
to resolve that anomaly,

we are going to discuss
this Structured English.

So, most programmers are unaware of the
large picture of the software.

So, they only rely on what their managers
tell them to do.

So, it is not possible that everyone who
are participating in that respective

software development project will have the
idea of the whole system, because the

whole system is a very large one.

So, most of the people who are working
involved in that particular project,

they know that what the managers are
asking them to do.

So, that much they can understand and that
much is reachable for them.

So, it is the responsibility of higher
software management to provide accurate

information to the programmers to develop
accurate yet fast code.

So, the communication between that manager
and the respective subordinates working

under his supervision, his or her
supervision, the communication should be good.

There should not be any miscommunication
between them.

So, different methods which use graphs or
diagrams at times might be interpreted in

a different way way by the different
people.

So, hence analysts and
designers of the software

come up with tools such
as structured English.

It is nothing but the description of what
is required to be coded and the how the

coding has to be done.

So, this structured English helps the
programmer to write error-free code.

And both the structured English and the
pseudo code, it will try to minimize the

misunderstanding, the gap
between the communication between

these managers and the
respective developers and the coders.

Structured English uses plain English
words in a structured programming paradigm.

So, it is not the ultimate
code, but a kind of

description that is required
to code and how to code it.

So, it will be not in
plain English, but in some

programming language
paradigm will be maintained there.

The following are the some tokens of
structure programming, if then else,

do, while, until.

So, these are the respective phrases which
will be used in our structure programming.

Analysts uses the same variable and data
name which are stored in the data

dictionary, making it much simpler to write
and understand the code appropriately.

So, let us go for one example.

So, we take the same example of customer
authentication in the online shopping

environment, which we discussed in our
HIPPO diagram and other diagrams prior.

So, this procedure to authenticate
customer can be written in structured

English like this.

So, enter customer name, seek customer
name in customer name database file.

If customer name found, then call
procedure user password authentication,

else print error message, call procedure
new customer request.

So, here you see this is the respective
structured English.

And it is almost in a certain programming
language paradigm.

You see here we are having this if,
then, else, and if.

So, it is quite similar with this Pascal.

So, that is why the corresponding codes
are there.

So, the code written in structured English
is more like our day-to-day spoken English.

But it cannot be implemented directly as a
code.

It is not like that you
can copy this code and

directly paste on to the
ID and go on compilation.

It is not like that.

And of the software and
the structured English

is independent of any
programming language.

That means that irrespective of the fact
that this particular software is going to

get implemented in .NET or PHP or in Java,
this structured English, this particular

structured English code will remain the
same.

So, it is language independent.

So, in this video, we have discussed
structured English.
