The Fib database

The Fib database does not belong to any Fib multimedia object. It is supplied with the Fib libraries / the Fib system and contains frequently used database objects, which can be used in Fib objects. Fib objects can use the database objects, without including these database objects (Fib objects). Database objects can be for example lines (with the input parameters for start and end points), rectangles or circles, but also trees, cars, character sets (fonts) or fractals. If for example a circle is needed for a Fib object, a corresponding parameterized database object can be used.

The implementation of the database objects can be adapted to the application environment. If for example for the display OpenGL is used, the database objects can be implemented directly with OpenGL primitives (e. g. triangles). In this manner with database objects the application performance can be improved. During the coding of the Fib objects this can be directly taken into account, by using database objects that have a good performance for the target application /program. These Fib objects are still viewable on all systems /with all programs with a high enough Fib database version, but on some faster.

Which objects, and identifier for these objects, a database contains, is determine by the database version. Databases with a higher database versions contain at last all database objects with the same identifiers, as databases with a lower database versions. In this way, it is ensured, that Fib objects are always forward compatible with newer database versions.

All identifiers for database objects are negative.
