This term project is about analyses and design of information system for  administration and managing business firm.System is designed as module system with unlimithed count of modules that coact or  are connected with another modules. Each module has its own data tables in database, own  Classes which make the middle layer of aplication  and graphical interface, but modules are not independent (one module can not work as a system).Iner communication among modules is based on database servers.Part of the application is its own database. To accomplish this project I had to familiarize myself with a problemathic of programming in  programming language C# and with database language PostgreSQL

The diploma thesis describes the design of your own web application within the long-term collaborative project co.llaborate.online. In a small team, we reflect on our own workflow and designer work. Currently, the common goal is the design and development of MVP for processing text, images and other graphic material into any graphic output - graphic editor co.design. As part of the project, we have also focused for a long time on the concept of compatible MVPs for text editing or data management and user research. The starting point of co.llaborate.online is the principle of DRY (Don't repeat yourself) and the principles of web technologies. We test how certain workflows can be automated and facilitate the collaboration of designers, text authors, editors, proofreaders, etc., or emancipate users from unnecessary activities.
