Most programmers are unaware of the large picture of software so they only rely on what their managers tell them to do. It is the responsibility of higher software management to provide accurate information to the programmers to develop accurate yet fast code.
Other forms of methods, which use graphs or diagrams, may are sometimes interpreted differently by different people.
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 code and how to code it. Structured English helps the programmer to write error-free code.
Other form of methods, which use graphs or diagrams, may are sometimes interpreted differently by different people. Here, both Structured English and Pseudo-Code tries to mitigate that understanding gap.
Structured English is the It uses plain English words in structured programming paradigm. It is not the ultimate code but a kind of description what is required to code and how to code it. The following are some tokens of structured programming.
IF-THEN-ELSE,
DO-WHILE-UNTIL
Analyst uses the same variable and data name, which are stored in Data Dictionary, making it much simpler to write and understand the code.
Example
We take the same example of Customer Authentication in the online shopping environment. This procedure to authenticate customer can be written in Structured English as:
Enter Customer_Name
SEEK Customer_Name in Customer_Name_DB file
IF Customer_Name found THEN
Call procedure USER_PASSWORD_AUTHENTICATE()
ELSE
PRINT error message
Call procedure NEW_CUSTOMER_REQUEST()
ENDIF
The code written in Structured English is more like day-to-day spoken English. It can not be implemented directly as a code of software. Structured English is independent of programming language.
