Fleet control

The application is initially implemented as a 2-tier WinForms client-server application, with the conceptual design focusing on the option of switching to a 3-tier architecture with relatively little effort. The architecture is based on the design recommendations for complex applications, as described by Microsoft and Martin Fowler, for example. This is then separated logically into a client layer with minimal complexity and a server layer that contains the business logic and database accesses. Database access is via typed data sets that are themselves encapsulated in a database access layer. The business logic, in turn, is divided into 3 specific subareas. For various reasons, a section of the business logic is implemented directly in the SQL Server 2008 in the form of views, stored procedures and transact SQL jobs.
