DataFlex – Quickstart building a web application (desktop)


Introduction

In this Course we are going to build a DataFlex Web Framework Application. We are going to build a desktop style application, which is aiming at high speed data entry on desktop devices, so using a keyboard and mouse. We are going to start off by defining our database and on top of our database we will define our business rules. On top of the business rules we are going to define the user interface, which in this case is desktop style web application. As opposed to drilldown style web application aiming at mobile devices or a Windows application. We are going to start off by having a look at the end result and then we are going to step through the process that is needed to build this application.


The application we are going to build today is a media library were we are going to store information about which DVD’s and books a specific person has. So, you will be able to look up items and see when they were bought, for what price, per person. When our application starts up a login screen comes up, this is a standard login screen that comes with the framework and that allows you to protect your data. After you login, you will see a menu bar and a toolbar, which is typical to a desktop style application and using the views menu you will be able to open a specific view. We will have a person’s view that opens up and it shows you a data entry screen were you can see the details of a person. You will be able to find records using the toolbar, the find keys and the lookup. The lookup will also be generated using one of the wizards and it will show you the data in a list form. We will also create a media view, which will allow you to add new media items, go through the media items and attach a media item to a specific person. To select the person we will reuse the same person look up that we have created for the person view.
