| + | ==== Textual descriptions for the libraries ==== | ||
| + | |||
| + | The libmvw.so should contain classes for the connection and query | ||
| + | to the database. | ||
| + | |||
| + | So that each application can individual access the database and it should be easy to design one commandline version and one GUI version. | ||
| + | |||
| + | The Scripts in the database should extend every function of the library. (prehook_class_function, posthook_class_function) | ||
| + | |||
| + | |||
| + | All details should be hidden between an Interface class, which | ||
| + | should be the only one accessible from the application. | ||
| + | (NO direct connection to the database, except: the user has the | ||
| + | right for that (admin_db)). | ||
| + | |||
