download, activation, configuration and updates with levels

the software has four levels:

• level 1: the system-core is always downloaded and it provides the functions for the activation and the configuration
• level 2: the application-core is always downloaded, it has the typical functions for the normal user
• level 3: the application-options can be chosen by the configuration depending on the user-license
• level 4: customized application-options can be chosen depending on the availability of customized applications, this level will be provided later

Level 1 and 2 will be delivered compressed (minified) and obfuscated, that guarantees a fast download and fast availability and it enforces security.

Level 3 is downloaded and installed on demand. The same will be with level 4 when it will be implemented.
