In the thesis a system architecture is presented that was designed and implemented to support certain applications in the translation company, which perform two key company processes. The two processes are human resource management and project management. The final qualitative system properties targeted are responsiveness, scalability, adaptability, interoperability and most importantly security. For this purpose, the system architecture consists of several mostly independent components. A front end, based on the ASP.NET MVC framework that works with the final user carry out the process of human resource management, a back end, based on ASP.NET WebAPI in the role of an application programming interface controlling access to the database, an IdentityServer security token service and the database itself, based on Microsoft SQL Server, which saves the data produced. Besides the components mentioned, which represent the core of the system, two more applications are considered a part of the system. SISI, a desktop Windows Forms application that aims to cover the process of project management and Projetex, a proprietary program meant to perform accounting services. In comparison to the previously established architecture, the new one substantially enhances each of the targeted system properties mentioned earlier.
