1.3. Realisation

After having created the concept of the application we are able to start with the realisation. In an earlier step you had to look for data at various sources and view the located data to define its quality. Even if you would have received data from a customer, it was necessary to view the data at an early stage. Normally the data has to be preprocessed before using it for the application.

By viewing the data at an early stage, you were able to estimate the time that has to be invested for the preparation of the data. The needed time for this preprocessing phase is not to be underestimated as you will see in this unit.

We will introduce you some methods how data can or has to be prepared for a project.
Only after having fulfilled this step, the real processing can be started. Because the realisation of a real application - even if it is a simple application - would be too time-consuming, we cannot realise an application in this lesson. Therefore, we concentrate on giving hints and introduce some examples.

After having created an application, it has to be varified that the application runs both in different browser software (if it is a Web application) and on different platforms.
