In my project the user will enter the name of the organization and it's floor map has to be displayed. the maps have to be made by us and need not be complicated at all. what i want to know is that what technologies can i use to do this? the backend has to be in either c++ or java with an oracle DB. should i use CAD? as i've never worked on CAD before i have no clue how it'll get integrated with C++ and if it can be useful for me or not or can i use C++ to make the maps? they need not be 3d maps, it can b 2d but need to be very presentable/colorful/easy to read etc
any directions will be very helpful.
