But can you build such applications without knowing any programming languages?
Each application is based on data .Data is stored in a database. The programming languages take the data as required and with the data it performs the job it was instructed to do.
So every application has a database and programming language to solve the problem. It also has interfaces that help a user to give the input of the problem and also to see the output of the same.
MS Excel can also do the same.
With MS Excel and a software called Spread Sheet Converter (earlier Excel Everywhere) anyone can develop a complete user friendly application.
Everyone using a computer need to know MS Excel which is a simple application that helps a user to perform various calculation and store data in a table like interface.
SC for JAVA will convert an excel datasheet into a completely interactive software application or a JAVA Bean.
SC for ASP will convert an excel datasheet into completely interactive asp page.
Excel contain an extensive set of functions that can help to calculate nearly every possible calculations in the world It also allow conditional statements which are great for decision making. If you need your data to be stored in a data base then, as MS Access can work simultaneously with Excel, the data can be stored in the Access database.
To make a software application, say to find the largest number among 3 numbers create an excel sheet like this one. Now install the spreadsheet converter.
You can find a SC tab in the top most toolbar of excel.
Colour the input column and click on the SC tab and select the wizard. As you have already coloured the input column just identify that colour in the wizard and then go on clicking ‘Next’. When you finish the last step SC will make your fully interactive software. See the working application here.
But the only drawback to make software in this way is that Excel can not modify an image. If image manipulation is your goal then you have to use My Desk Professional. My Desk is a without code software maker which enables anyone to develop image manipulation and system maintenance software without code. Though some simple basic codes are required for better customization.
Another without code software you can find useful is Paseo Express which enable anyone without any knowledge of coding develop scripts like search engine, form verification etc.
