A method and system comprise interfacing with the Relational Database (304), the Network Designer (302) decides to change or view a design configuration. The system accesses the design of interest based upon a user interaction. Any particular design configuration contains the as-built design, which represents the current documented network, plus the historic and future designs. The Network Designer (302) can access the historic designs, the as-built design or any future designs. For instance, Design F (320) contains the As-Built Design (310) plus any changes made to Design A (312) and Design E (318). Private designs: Design B (314), Design C (316), and Design F (320) do not share their information, but they are affected by Public Designs with earlier effective dates. When a design is committed, it becomes the new as-built design. Historic Design B (306), Historic Design A (308), and the As-Built Design (310) are considered committed views, while future designs are uncommitted views. Future designs are committed in the order of their effective dates.
