Abstract

The embodiment of the invention discloses a method and device for processing and querying data. The processing method comprises the following steps of: establishing a first level index for the data, wherein the data is stored in at least one file, the first level index is used for indexing each file, and the corresponding data is stored in the file; and respectively establishing a second level index for each file, wherein the second level index is used for indexing the corresponding data in the corresponding file. The querying method comprises the following steps of: utilizing the first level index to search within each file according to a received data querying request, thereby acquiring a queried file storing the data queried by the querying request; and then utilizing the second level index to search within the queried file according to the data querying request, thereby acquiring the data queried by the querying request. By using the method, the speed for querying a large amount of data is increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data processing and query method and device. Background technique [0002] A telecommunication service CDR (Call Detail Record, call detail record) is data provided in a telecommunication network to record user call event information. For example, a typical call CDR includes a lot of information such as the user's communication number, the other party's number, call time, and service type. With the continuous enrichment of current telecommunication services, here for convenience, we collectively refer to the recorded data of calls, text messages, mobile Internet and other services as CDR data. For example, a typical mobile Internet CDR includes user communication number, URL (Uniform Resource Locator, Uniform Resource Locator), HTTP (HyperText Transfer Protocol, Hypertext Transfer Protocol) status code, session time, uplink and downlink traffic and many other information...
