Busy users will not be interested in a system that is difficult to use, but the system must still give reasonable results. So it is necessary to make it as easy as possible for a user to enter the information the software needs. Structured languages can be the solution to this problem because they can be understood by a user, and the language is constructed using mathematical rules. Therefore the structured language presents a mathematical representation to the computer and a natural language or diagrammatic representation to the user. (Borthick et al. 2001) explain however, that ambiguity in natural language can make it difficult to translate natural language into SQL.

It is possible to create an extra layer to enable users to specify commands in structured language. This approach of adding extra layers is the way visual programming works. Users provide the information the program needs at the visual interface layer and program code is created automatically. The layers provide the bridge between abstract ideas and computer code. If this approach is taken to its logical conclusion, we could allow the user to specify what the computer should do. Then each layer would communicate this to the layer below until the computer performs the action required. A simple example of this approach is the use of spreadsheets. A user can specify a calculation in mathematical terms using a formula. The spreadsheet then calculates the result of the formula. The user can change the formula if it is incorrect without any need to write code or re-compile. This accounts for the popularity of spreadsheets. However, spreadsheets do not provide the centralised and structured data-store required for a distributed system. Such systems can be made much more powerful if the information is codified into a relational database structure. Then On-Line Analytical Processing (OLAP) can be used for more sophisticated data collection and analysis. Lau et al. (2001) explain how OLAP displays a multi-dimensional view of aggregated data, and presents a Rule-Based Analytical Processing (RBOLAP) model which can be used for decision support. The use of RBOLAP techniques is demonstrated using a case study on a mould and die information network.

Sutton (2001) and Huber (2001) illustrate how codifying knowledge into a knowledge based system for decision support is likely to be very difficult. Most people ‘just do’ a task and therefore never write down instructions for others. This highlights the difficulty of getting information into a knowledge base when it may be either only in individuals’ minds, or completely unstructured.

Information is scattered within organisations and often not held in such a structured way as to be easily accessed by employees or software. This problem was examined by Lau et al (2005) using the example of McDonnell Douglas (now part of Boeing), that demonstrated how difficult it is to gather unstructured knowledge. Therefore, it is important that research is undertaken into methods of capturing, structuring, distributing, analysing, and visualising information.

I am a Researcher in the final year of my PhD. I specialise in applying Semantic Web techniques. My current research is on a technique of ‘User Driven Modelling/Programming’. My intention is to enable non-programmers to create software from a user interface that allows them to model a particular problem or scenario. This involves a user entering information visually in the form of a tree diagram. I am attempting to develop ways of automatically translating this information into program code in a variety of computer languages. This is very important and useful for many employees that have insufficient time to learn programming languages. I am looking to research visualisation, and visualisation techniques to create a human computer interface that allows non experts to create software.

What is unstructured programming language?

It is basically a subset of procedural programs. It is basically a procedural program. In this, programmers are allowed to code a program simply by dividing the program into modules or smaller units. In this, programmers are not allowed code divide programs into small units.

What is the difference between structured programming and modular programming?

Answer: Structured Programming is designed which focuses on process/ logical structure and then data required for that process. Object Oriented Programming is designed which focuses on data. Structured Programming is also known as Modular Programming and a subset of procedural programming language.

Is C++ a structured programming language?

C++ language code can be either structured, or object-oriented. … C++ grew from C which is a structured programming language. In structured programming, you have data, and you can write functions to process the data.

Is Java is a structured programming language?

As its name suggests, structured programming is done in a structured programming language and PHP, C#, C++, Java, Visual Basic, and Python are such languages. The structured programming concept was formalized in 1966 by Corrado Böhm and Giuseppe Jacopini.

What is structured programming with example?

Structured Programming in Visual Basic

Structured programming is a program written with only the structured programming constructions: (1) sequence, (2) repetition, and (3) selection. Sequence. Lines or blocks of code are written and executed in sequential order. Example: x = 5.

What programming languages are procedural?

A procedural language is a computer programming language that follows, in order, a set of commands. Examples of computer procedural languages are BASICCFORTRANJava, and Pascal. Procedural languages are some of the common types of programming languages used by script and software programmers.

Why C is a structured programming language?

C is called structured modular programming language because while solving large and complex problem, C programming language divides the problem into smaller modules called functions. Each of these functions has specific job. And entire problem is solved by collecting such functions or smaller modules.

What is the goal of structured coding?

Explanation: The main goal of structured programming is to get an understanding about the flow of control in the given program text. In structure programming various control structures such as switch-case, if-then-else, while, etc. allows a programmer to decode the flow of the program easily.
