A method and system for matching multi-dimensional data units in an electronic information system, the method comprising: arranging interface modules and cache modules on a front-end processing device, and one interface module and two or more cache modules forming a matching module; performing service processing for at least two dimensions on a remote device, and writing a processed multi-dimensional data unit into the cache module of the front-end processing device; and after the interface module receives a user request, determining dimension information corresponding to a current scene of the user request, inquiring a matched multi-dimensional data unit in the catch module of the matching module according to the dimension information, and sending the multi-dimensional data unit obtained by the query to an output module. The method and the system are capable of improving the efficiency and real-time performance of matching a multi-dimensional information scene to a multi-dimensional data unit.
