The DSETA framework is a complete solution for the conception, development and production of data sharing systems based on a client-server architecture. DSETA represent, for an Architect, the shortest way between his concept of data sharing system to the production step. DSETA is based on two generic and existing Client and Server applications, configured by functional Rules. These powerful Rules are edited by the Architect; they define the data structure, the access rights, the data processing, and the ease of use. DSETA is built upon Microsoft C# .NET, Web Services, and SQL Server technology. These technologies remain directly accessible through the DSETA framework: developers can complete by C# programming any Architect initiated DSETA service.
