The invention discloses a data redundancy energy efficiency detection method. A key word is inputted into a related application; and data fuzzy searching is carried out in a background oracle database simultaneously to search matched information. If searching is matched, prompting is carried out if corresponding data information exists during the background searching process and the related information is displayed, so that the user can select and use the information; and if multiple identical data occurs during the searching process, data with integrated basic data information are selected. If searching is not matched, prompting is carried out if no corresponding data information exists during the background searching process and data are recorded again and are stored. The accuracy and uniqueness of provided data can be realized by examining data, verifying existing data, and inquiring and verifying the necessary data; and a data redundancy situation is avoided.
