BRON2 - Simple example

 

These 10 lines of BRON code clearly and concisely describe three objects, their relationships (1 to many and 1 to 1) and the data that they each hold. See What it does for you for a detailed description.

Using BRON2C, this BRON code produced 478 lines of C code and a further 96 lines of C header code.

    OBJECT firstObject
    	FIELD int aninteger
    	FIELD char* sometext
    	LIST theOtherObject

    OBJECT theOtherObject
    	KEY char* findMe
    	EFIELD int Mustsupplythisvalue
    	REF yetAnotherObject

    OBJECT yetAnotherObject
    	FIELD char* whatever

We suggest that you examine the BRON code, read What it does for you for an overview of what BRON2C does for you, then take a look at the generated .c and .h files

A LIST represents a 1 to many relationship

A REF represents a 1 to 1 relationship  

The VisualBRON Information model shown below is equivalent to the BRON2 code, VisualBRON allows managed (MLIST) and unmanaged lists (LIST), all BRON2 lists are managed.
