EULANDA® is based on the Microsoft SQL Server. All data and settings are stored in a single database. This means: not only the actual data, such as addresses and invoices, but also, for example, the report templates and all user settings are managed there. No relevant data is stored on the client computer - either as files or in the Windows registry.
By making intensive use of the possibilities of Transact-SQL we have outsourced the complete business logic - the classic middle tier - to the server. This creates a central starting point for you as a developer to implement your own extensions.
In order for your extensions to be compatible with future updates of EULANDA®, but also to avoid malfunctions, you must observe a few important rules.
