Geographical attribution information inquiry method oriented to MapReduce frame

Abstract

The invention discloses a geographical attribution information inquiry method oriented to a MapReduce frame. The method includes: designing an encoding table TIP for converting IP addresses into geographical attribution information, wherein the encoding table TIP is achieved through a one-dimensional array, each array element is an integer G, and the array index x is an integer acquired through IP address conversion; designing geographical attribution information encoding detail tables, wherein the detail tables includes a country encoding detail table TCODE_COUNTRY, a province/region encoding detail table TCODE_REGION, a city encoding detail table TCODE_CITY and an Internet service provider encoding detail table TCODE_ISP; using the encoding table TIP and the four geographical attribution information encoding detail tables to inquire geographical attribution information encoding or details corresponding to IP addresses, and using bit operation and addressing operations to accelerate the inquiry; building an inquiry service based on Web and oriented to the MapReduce frame to provide support for massive data processing of computing environments. The geographical attribution information inquiry method is fast in inquiry and small in storage space occupation.

Description

【Technical field】 [0001] The invention relates to the technical field of the Internet, in particular to a method for querying geographic attribution information oriented to a MapReduce framework. 【Background technique】 [0002] With the development of Internet technology, the data stored in the information system is becoming larger and larger. In order to make full use of the MapReduce framework to analyze these data, the data must be preprocessed, including obtaining the geographical attribution information of the data. For example, in the tax system, it is often necessary to analyze the tax declaration records provided by various units and enterprises in various places, and to find possible problems by comparing and screening the geographic information of the original data. The acquisition of geographic attribution information of the data mainly depends on the query and conversion of the geographic attribution information corresponding to the IP address in the data, which ...
