THE .NET Concilieri Home Über uns Service Know How Portfolio Projekte Success Story Kontakt		Success Story : Internet Application SecurAdmin Client and Requirements Our client Securmark AG offers a service for users, to register their precious goods through a .NET Web Application. For administrative purposes of this registered goods, a corresponding tool was not at hand. Securmark AG contracted our company to develop such an administration tool that must adhere to the following base requirements:   ->  Develop an application for the administration of their existing .NET        internet product Securmark® - Register.   ->  Administrative activities and reporting can be carried out only through        successfully authenticated administrators.   ->  Complete language independent because administrators are located in        different countries, hence they use their language.   ->  Maintenance and deployment for future updates must be kept at a        minimum. This is true as well for the languages. Solution Based on the requirements, our solution is a language independent .NET Web Application with Forms Authentication and a database that contains the specific languages, which the .NET Web application dynamically calls at runtime. Use Case Analysis Through several interviews we analyzed the business and use cases for the administrative tool. Herewith we established a common language, helped the client to identify the stakeholders goals and supported him to define the functionality the tool must deliver. Because of our experience, this process was done in a very short time, which helped the client to save time and costs. Iterative Development Simultaneously, we developed the base software architecture and implemented some major use cases (functionality). With this first Web administration tool release, we built an excellent base to demonstrate the client how things are working and to figure out, if the application meets the clients goals. Proceeding like this, we adopted the iterative development process and the Web administrative tool evolved gradually, thus our client could see the development progress and we finally met the clients goals and qualities. Security During development we paid strong attention on the security, which was very much appreciated by our client. All input is checked against plausibility and validity (semantic and syntax), i.e. the input of an email address must conform to a predefined email format, otherwise the input is rejected with a corresponding message for the user. As a matter of course, authentication is implemented as well. As soon as the administrator is successfully authenticated, the communication between the browser and the server is secured with SSL, hence the data transfer is 128 bit encoded. Database As backend serves the Microsoft SQL Server 2000 database, which contains all the data from the users and their precious goods. To realize the Web administration tool inherently language independent, we took the solution to manage the languages completely within the database. Thus, decoupling the Web application source from the languages, gives our client the advantage of dynamically change or add languages according his needs without to change anything within the application source code. Technologies We used the well established Microsoft technologies ASP.NET and ADO.NET in conjunction with the Microsoft database SQL Server 2000. The applied programming languages are C# and T-SQL for the stored procedures and triggers. Architecture The solution is implemented with a classical 3-tier architecture. Because of the complexity of certain database queries and to accomplish high cohesion as well as separation of concerns, we developed a database access component. Conclusion Through our straight engagement and our .NET and software engineering expertise, our client has now a secure and reliable .NET Web administration tool, which he uses for his daily duty.
