One of the sensitive points of application softwares is the programming of the user interface. In particular, the acquisition and the automatic validation of data capture demands great efforts and is rarely programmed in a satisfactory manner. Our research studies are based on the development of a theoretical data acquisition and validation model, as well as the fulfilment of these ideas using computer tools. This paper shows the different choices which we have studied and the tools we have developed to put these into effect. The tools we have created to take these considerations into account is called OVIDE and is perfectly integrated to the chosen development environment.
